Akira came directly, breaking all tradition. Was that it? Had he followed form-had he asked his mother to speak to his father to approach a go-between-would Chie have been more receptive?He came on a winter's eve. He pounded on the door while a cold rain beat on the shuttered veranda, so at first Chie thought him only the wind. The maid knew better. Chie heard her soft scuttling footsteps, the creak of the door. Then the maid brought acalling card to the drawing room, for Chie.Chie was reluctant to go to her guest; perhaps she was feeling too cozy. She and Naomi were reading at a low table set atop a charcoal brazier. A thick quilt spread over the sides of the table so their legs were tucked inside with the heat."Who is it at this hour, in this weather?" Chie questioned as she picked the name card off the maid's lacquer tray."Shinoda, Akira. Kobe Dental College," she read. Naomi recognized the name. Chie heard a soft intake of air."I think you should go," said Naomi. twenties, slim and serious, wearing the blackmilitary-style uniform of a student. As he bowed-his hands hanging straight down, a black cap in one, a yellow oil-paper umbrella in the other-Chie glanced beyond him. In the glistening surface of the courtyard's rain-drenched paving 30 stones, she saw his reflection like a dark double."Madame," said Akira, "forgive my disruption, but I come with a matter of urgency."His voice was soft, refined. He straightened and stole a deferential peek at her face.35 In the dim light his eyes shone with sincerity. Chie felt herself starting to like him."Come inside, get out of this nasty night. Surely your business can wait for a moment or two.""I don't want to trouble you. Normally I would 40 approach you more properly but I've received word of a position. I've an opportunity to go to America, as dentist for Seattle's Japanese community.""Congratulations," Chie said with amusement. "That is an opportunity, I'm sure. But how am I 45 involved?"Even noting Naomi's breathless reaction to the name card, Chie had no idea. Akira's message, delivered like a formal speech, filled her with maternal amusement. You know how children speak50 so earnestly, so hurriedly, so endearingly about things that have no importance in an adult's mind? That's how she viewed him, as a child. It was how she viewed Naomi. Even though Naomi was eighteen and training endlessly in the arts 55 needed to make a good marriage, Chie had made no effort to find her a husband.Akira blushed."Depending on your response, I may stay in Japan. I've come to ask for Naomi's hand."60 Suddenly Chie felt the dampness of the night."Does Naomi know anything of your... ambitions?""We have an understanding. Please don't judge my candidacy by the unseemliness of this proposal. I65 ask directly because the use of a go-between takes much time. Either method comes down to the same thing: a matter of parental approval. If you give your consent, I become Naomi's yoshi. ${ }^{*}$ We'll live in the House of Fuji. Without your consent, I must go to 70 America, to secure a new home for my bride."Eager to make his point, he'd been looking her full in the face. Abruptly, his voice turned gentle. "I see I've startled you. My humble apologies. I'll take no more of your evening. My address is on my card. If 75 you don't wish to contact me, I'll reapproach you in two weeks' time. Until then, good night."He bowed and left. Taking her ease, with effortless grace, like a cat making off with a fish."Mother?" Chie heard Naomi's low voice and 80 turned from the door. "He has asked you?"The sight of Naomi's clear eyes, her dark brows gave Chie strength. Maybe his hopes were preposterous."Where did you meet such a fellow? Imagine! $\mathrm{He}$ 85 thinks he can marry the Fuji heir and take her to America all in the snap of his fingers!"Chie waited for Naomi's ripe laughter.Naomi was silent. She stood a full half minute looking straight into Chie's eyes.

The chemical formula of deoxyribonucleic acid (DNA) is now well established. The molecule is a very long chain, the backbone of which consists of a regular alternation of sugar and phosphate groups.To each sugar is attached a nitrogenous base, which can be of four different types. Two of the possible bases-adenine and guanine - are purines, and the other two-thymine and cytosine-are pyrimidines. So far as is known, the sequence of bases along the 10 chain is irregular. The monomer unit, consisting of phosphate, sugar and base, is known as a nucleotide.The first feature of our structure which is of biological interest is that it consists not of one chain, but of two. These two chains are both coiled around15 a common fiber axis. It has often been assumed that since there was only one chain in the chemical formula there would only be one in the structural unit. However, the density, taken with the X-ray evidence, suggests very strongly that there are two.The other biologically important feature is the manner in which the two chains are held together. This is done by hydrogen bonds between the bases. The bases are joined together in pairs, a single base from one chain being hydrogen-bonded to a single25 base from the other. The important point is that only certain pairs of bases will fit into the structure.One member of a pair must be a purine and the other a pyrimidine in order to bridge between the two chains. If a pair consisted of two purines, for 30 example, there would not be room for it.We believe that the bases will be present almost entirely in their most probable forms. If this is true, the conditions for forming hydrogen bonds are more restrictive, and the only pairs of bases possible are: 35 adenine with thymine, and guanine with cytosine. Adenine, for example, can occur on either chain; but when it does, its partner on the other chain must always be thymine.The phosphate-sugar backbone of our model is 40 completely regular, but any sequence of the pairs of bases can fit into the structure. It follows that in a long molecule many different permutations are possible, and it therefore seems likely that the precise sequence of bases is the code which carries the45 genetical information. If the actual order of the bases on one of the pair of chains were given, one could write down the exact order of the bases on the other one, because of the specific pairing. Thus one chain is, as it were, the complement of the other, and it is50 this feature which suggests how the deoxyribonucleic acid molecule might duplicate itself.The table shows, for various organisms, the percentage of each of the four types of nitrogenous bases in that organism's DNA.\begin{center}\begin{tabular}{|l|c|c|c|c|}\hline\multicolumn{5}{|c|}{Base Composition of DNA} \\\hline\multirow{3}{*}{Organism} & \multicolumn{4}{|c|}{$\begin{array}{c}\text { Percentage of base } \\\text { in organism's DNA }\end{array}$} \\\cline { 2 - 5 }& $\begin{array}{c}\text { adenine } \\ (\%)\end{array}$ & $\begin{array}{c}\text { guanine } \\ (\%)\end{array}$ & $\begin{array}{c}\text { cytosine } \\ (\%)\end{array}$ & $\begin{array}{c}\text { thymine } \\ (\%)\end{array}$ \\\hline& 26.8 & 22.8 & 23.2 & 27.2 \\\hlineOctopus & 33.2 & 17.6 & 17.6 & 31.6 \\\hlineChicken & 28.0 & 22.0 & 21.6 & 28.4 \\\hlineRat & 28.6 & 21.4 & 20.5 & 28.4 \\\hlineHuman & 29.3 & 20.7 & 20.0 & 30.0 \\\hlineGrasshopper & 29.3 & 20.5 & 20.7 & 29.3 \\\hlineSea urchin & 32.8 & 17.7 & 17.3 & 32.1 \\\hlineWheat & 27.3 & 22.7 & 22.8 & 27.1 \\\hlineYeast & 31.3 & 18.7 & 17.1 & 32.9 \\\hlineE. coli & 24.7 & 26.0 & 25.7 & 23.6 \\\hline\end{tabular}\end{center}Q: The authors' main purpose of including the information about $\mathrm{X}$-ray evidence and density is to Answer Choices: (A)establish that DNA is the molecule that carries the genetic information.

The chemical formula of deoxyribonucleic acid (DNA) is now well established. The molecule is a very long chain, the backbone of which consists of a regular alternation of sugar and phosphate groups.To each sugar is attached a nitrogenous base, which can be of four different types. Two of the possible bases-adenine and guanine - are purines, and the other two-thymine and cytosine-are pyrimidines. So far as is known, the sequence of bases along the 10 chain is irregular. The monomer unit, consisting of phosphate, sugar and base, is known as a nucleotide.The first feature of our structure which is of biological interest is that it consists not of one chain, but of two. These two chains are both coiled around15 a common fiber axis. It has often been assumed that since there was only one chain in the chemical formula there would only be one in the structural unit. However, the density, taken with the X-ray evidence, suggests very strongly that there are two.The other biologically important feature is the manner in which the two chains are held together. This is done by hydrogen bonds between the bases. The bases are joined together in pairs, a single base from one chain being hydrogen-bonded to a single25 base from the other. The important point is that only certain pairs of bases will fit into the structure.One member of a pair must be a purine and the other a pyrimidine in order to bridge between the two chains. If a pair consisted of two purines, for 30 example, there would not be room for it.We believe that the bases will be present almost entirely in their most probable forms. If this is true, the conditions for forming hydrogen bonds are more restrictive, and the only pairs of bases possible are: 35 adenine with thymine, and guanine with cytosine. Adenine, for example, can occur on either chain; but when it does, its partner on the other chain must always be thymine.The phosphate-sugar backbone of our model is 40 completely regular, but any sequence of the pairs of bases can fit into the structure.

Close at hand is a bridge over the River Thames, an admirable vantage ground for us to make a survey. The river flows beneath; barges pass, laden with timber, bursting with corn; there on one side are 5 the domes and spires of the city; on the other, Westminster and the Houses of Parliament. It is a place to stand on by the hour, dreaming. But not now. Now we are pressed for time. Now we are here to consider facts; now we must fix our eyes upon the10 procession-the procession of the sons of educated men.There they go, our brothers who have been educated at public schools and universities, mounting those steps, passing in and out of those15 doors, ascending those pulpits, preaching, teaching, administering justice, practising medicine, transacting business, making money. It is a solemn sight always - a procession, like a caravanserai crossing a desert. ... But now, for the past twenty20 years or so, it is no longer a sight merely, a photograph, or fresco scrawled upon the walls of time, at which we can look with merely an esthetic appreciation. For there, trapesing along at the tail end of the procession, we go ourselves. And that25 makes a difference. We who have looked so long at the pageant in books, or from a curtained window watched educated men leaving the house at about nine-thirty to go to an office, returning to the house at about six-thirty from an office, need look passively30 no longer. We too can leave the house, can mount those steps, pass in and out of those doors, ... make money, administer justice. ... We who now agitate these humble pens may in another century or two speak from a pulpit. Nobody will dare contradict us35 then; we shall be the mouthpieces of the divine spirit-a solemn thought, is it not? Who can say whether, as time goes on, we may not dress in military uniform, with gold lace on our breasts, swords at our sides, and something like the old40 family coal-scuttle on our heads, save that that venerable object was never decorated with plumes of white horsehair. You laugh-indeed the shadow of the private house still makes those dresses look a little queer. We have worn private clothes so 45 long. ... But we have not come here to laugh, or to talk of fashions-men's and women's. We are here, on the bridge, to ask ourselves certain questions. And they are very important questions; and we have very little time in which to answer them. The0 questions that we have to ask and to answer about that procession during this moment of transition are so important that they may well change the lives of all men and women for ever. For we have to ask ourselves, here and now, do we wish to join that55 procession, or don't we? On what terms shall we join that procession? Above all, where is it leading us, the procession of educated men? The moment is short; it may last five years; ten years, or perhaps only a matter of a few months longer. ... But, you will60 object, you have no time to think; you have your battles to fight, your rent to pay, your bazaars to organize. That excuse shall not serve you, Madam. As you know from your own experience, and there are facts that prove it, the daughters of educated men65 have always done their thinking from hand to mouth; not under green lamps at study tables in the cloisters of secluded colleges. They have thought while they stirred the pot, while they rocked the cradle. It was thus that they won us the right to our70 brand-new sixpence. It falls to us now to go on thinking; how are we to spend that sixpence? Think we must. Let us think in offices; in omnibuses; while we are standing in the crowd watching Coronations and Lord Mayor's Shows; let us think ... in the75 gallery of the House of Commons; in the Law Courts; let us think at baptisms and marriages and funerals. Let us never cease from thinking-what is this "civilization" in which we find ourselves? What are these ceremonies and why should we take part in80 them? What are these professions and why should we make money out of them? Where in short is it leading us, the procession of the sons of educated men?Q: The main purpose of the passage is to Answer Choices: (A)emphasize the value of a tradition.

That's the message from a first-of-its-kind forum on mining beyond Earth.Convened in Sydney by the Australian Centre for 5 Space Engineering Research, the event brought together mining companies, robotics experts, lunar scientists, and government agencies that are all working to make space mining a reality.The forum comes hot on the heels of the 102012 unveiling of two private asteroid-mining firms. Planetary Resources of Washington says it will launch its first prospecting telescopes in two years, while Deep Space Industries of Virginia hopes to be harvesting metals from asteroids by 2020 . Another15 commercial venture that sprung up in 2012, Golden Spike of Colorado, will be offering trips to the moon, including to potential lunar miners.Within a few decades, these firms may be meeting earthly demands for precious metals, such as20 platinum and gold, and the rare earth elements vital for personal electronics, such as yttrium and lanthanum. But like the gold rush pioneers who transformed the western United States, the first space miners won't just enrich themselves. They also hope25 to build an off-planet economy free of any bonds with Earth, in which the materials extracted and processed from the moon and asteroids are delivered for space-based projects.In this scenario, water mined from other 30 worlds could become the most desired commodity. "In the desert, what's worth more: a kilogram of gold or a kilogram of water?" asks Kris Zacny of HoneyBee Robotics in New York. "Gold is useless. Water will let you live."35 Water ice from the moon's poles could be sent to astronauts on the International Space Station for drinking or as a radiation shield. Splitting water into oxygen and hydrogen makes spacecraft fuel, so ice-rich asteroids could become interplanetary 40 refuelling stations. Companies are eyeing the iron, silicon, and aluminium in lunar soil and asteroids, which could be used in 3D printers to make spare parts or machinery. Others want to turn space dirt into 45 concrete for landing pads, shelters, and roads.\section{Passage 2}The motivation for deep-space travel is shifting from discovery to economics. The past year has seen a flurry of proposals aimed at bringing celestial riches down to Earth. No doubt this will make a few0 billionaires even wealthier, but we all stand to gain: the mineral bounty and spin-off technologies could enrich us all.But before the miners start firing up their rockets, we should pause for thought. At first glance, space55 mining seems to sidestep most environmental concerns: there is (probably!) no life on asteroids, and thus no habitats to trash. But its consequences -both here on Earth and in space -merit careful consideration.60 Part of this is about principles. Some will argue that space's "magnificent desolation" is not ours to despoil, just as they argue that our own planet's poles should remain pristine. Others will suggest that glutting ourselves on space's riches is not an65 acceptable alternative to developing more sustainable ways of earthly life.History suggests that those will be hard lines to hold, and it may be difficult to persuade the public that such barren environments are worth preserving.70 After all, they exist in vast abundance, and even fewer people will experience them than have walked through Antarctica's icy landscapes.There's also the emerging off-world economy to consider. The resources that are valuable in orbit and 75 beyond may be very different to those we prize on Earth. Questions of their stewardship have barely been broached-and the relevant legal and regulatory framework is fragmentary, to put it mildly.Space miners, like their earthly counterparts, are 80 often reluctant to engage with such questions.One speaker at last week's space-mining forum in Sydney, Australia, concluded with a plea that regulation should be avoided. But miners have much to gain from a broad agreement on the for-profit 85 exploitation of space. Without consensus, claims will be disputed, investments risky, and the gains made insecure. It is in all of our long-term interests to seek one outQ: The author of Passage 1 indicates that space mining could have which positive effect? Answer Choices: (A)It could yield materials important to Earth's economy. (B)It could raise the value of some precious metals on Earth. (C)It could create unanticipated technological innovations. (D)It could change scientists' understanding of space resources.

Miss Grace Spivey arrived in Threestep, Georgia, in August 1938. She stepped off the train wearing a pair of thick-soled boots suitable for hiking, a navyblue dress, and a little white tam that rode the wavesof her red hair at a gravity-defying angle. August was a hellish month to step off the train in Georgia, although it was nothing, she said, compared to the 119 degrees that greeted her when she arrived one time in Timbuktu, which, she assured us, was a real 10 place in Africa. I believe her remark irritated some of the people gathered to welcome her on the burned grass alongside the tracks. When folks are sweating through their shorts, they don't like to hear that this is nothing compared to someplace else. Irritated or15 not, the majority of those present were inclined to see the arrival of the new schoolteacher in a positive light. Hard times were still upon us in 1938, but, like my momma said, "We weren't no poorer than we'd ever been," and the citizens of Threestep were in the 20 mood for a little excitement.Miss Spivey looked like just the right person to give it to them. She was, by almost anyone's standards, a woman of the world. She'd gone to boarding schools since she was six years old; she'd 25 studied French in Paris and drama in London; and during what she called a "fruitful intermission" in her formal education, she had traveled extensively in the Near East and Africa with a friend of her grandmother's, one Janet Miller, who was a medical30 doctor from Nashville, Tennessee. After her travels with Dr. Miller, Miss Spivey continued her education by attending Barnard College in New York City. She told us all that at school the first day. When my little brother Ralphord asked what did she study at35 Barnyard College, Miss Spivey explained that Barnard, which she wrote on the blackboard, was the sister school of Columbia University, of which, she expected, we all had heard.It was there, she told us, in the midst of trying to 40 find her true mission in life, that she wandered one afternoon into a lecture by the famous John Dewey, who was talking about his famous book, Democracy and Education. Professor Dewey was in his seventies by then, Miss Spivey said, but he still liked to chat45 with students after a lecture-especially female students, she added-sometimes over coffee, and see in their eyes the fire his words could kindle. It was after this lecture and subsequent coffee that Miss Spivey had marched to the Teacher's College and 50 signed up, all aflame. Two years later, she told a cheery blue-suited woman from the $\mathrm{WPA}^{1}$ that she wanted to bring democracy and education to the poorest, darkest, most remote and forgotten corner of America.55 They sent her to Threestep, Georgia.Miss Spivey paused there for questions, avoiding my brother Ralphord's eye.What we really wanted to know about-all twenty-six of us across seven grade levels in the one 60 room-was the pearly white button hanging on a string in front of the blackboard behind the teacher's desk up front. That button on a string was something new. When Mavis Davis (the only bona fide seventh grader, at age thirteen) asked what it was for, Miss65 Spivey gave the string a tug, and to our astonishment, the whole world-or at least a wrinkled map of it-unfolded before our eyes. Her predecessor, Miss Chandler, had never once made use of that map, which was older than our fathers, and until that70 moment, not a one of us knew it was there.Miss Spivey showed us on the map how she and Dr. Janet Miller had sailed across the Atlantic Ocean and past the Rock of Gibraltar into theMediterranean Sea. Using the end of a ruler, she75 gently tapped such places as Morocco and Tunis and Algiers to mark their route along the top of Africa. They spent twenty hours on the train to Baghdad, she said, swathed in veils against the sand that crept in every crack and crevice.80 "And can you guess what we saw from the train?" Miss Spivey asked. We could not. "Camels!" she said. "We saw a whole caravan of camels." She looked around the room, waiting for us to be amazed and delighted at the thought.85 We all hung there for a minute, thinking hard, until Mavis Davis spoke up."She means like the three kings rode to Bethlehem," Mavis said, and she folded her hands smugly on her seventh-grade desk in the back of the 90 room.Miss Spivey made a mistake right then. Instead of beaming upon Mavis the kind of congratulatory smile that old Miss Chandler would have bestowed on her for having enlightened the rest of us, Miss95 Spivey simply said, "That's right."1 The Works Progress Administration (WPA) was a government agency that hired people for public and cultural development projects and services.Q: The narrator of the passage can best be described as Answer Choices: (A)one of Miss Spivey's former students. (B)Miss Spivey's predecessor. (C)an anonymous member of the community. (D)Miss Spivey herself. 2

Miss Grace Spivey arrived in Threestep, Georgia, in August 1938. She stepped off the train wearing a pair of thick-soled boots suitable for hiking, a navyblue dress, and a little white tam that rode the wavesof her red hair at a gravity-defying angle. August was a hellish month to step off the train in Georgia, although it was nothing, she said, compared to the 119 degrees that greeted her when she arrived one time in Timbuktu, which, she assured us, was a real 10 place in Africa. I believe her remark irritated some of the people gathered to welcome her on the burned grass alongside the tracks. When folks are sweating through their shorts, they don't like to hear that this is nothing compared to someplace else. Irritated or15 not, the majority of those present were inclined to see the arrival of the new schoolteacher in a positive light. Hard times were still upon us in 1938, but, like my momma said, "We weren't no poorer than we'd ever been," and the citizens of Threestep were in the 20 mood for a little excitement.Miss Spivey looked like just the right person to give it to them. She was, by almost anyone's standards, a woman of the world. She'd gone to boarding schools since she was six years old; she'd 25 studied French in Paris and drama in London; and during what she called a "fruitful intermission" in her formal education, she had traveled extensively in the Near East and Africa with a friend of her grandmother's, one Janet Miller, who was a medical30 doctor from Nashville, Tennessee. After her travels with Dr. Miller, Miss Spivey continued her education by attending Barnard College in New York City. She told us all that at school the first day. When my little brother Ralphord asked what did she study at35 Barnyard College, Miss Spivey explained that Barnard, which she wrote on the blackboard, was the sister school of Columbia University, of which, she expected, we all had heard.It was there, she told us, in the midst of trying to 40 find her true mission in life, that she wandered one afternoon into a lecture by the famous John Dewey, who was talking about his famous book, Democracy and Education. Professor Dewey was in his seventies by then, Miss Spivey said, but he still liked to chat45 with students after a lecture-especially female students, she added-sometimes over coffee, and see in their eyes the fire his words could kindle. It was after this lecture and subsequent coffee that Miss Spivey had marched to the Teacher's College and 50 signed up, all aflame. Two years later, she told a cheery blue-suited woman from the $\mathrm{WPA}^{1}$ that she wanted to bring democracy and education to the poorest, darkest, most remote and forgotten corner of America.55 They sent her to Threestep, Georgia.Miss Spivey paused there for questions, avoiding my brother Ralphord's eye.What we really wanted to know about-all twenty-six of us across seven grade levels in the one 60 room-was the pearly white button hanging on a string in front of the blackboard behind the teacher's desk up front. That button on a string was something new. When Mavis Davis (the only bona fide seventh grader, at age thirteen) asked what it was for, Miss65 Spivey gave the string a tug, and to our astonishment, the whole world-or at least a wrinkled map of it-unfolded before our eyes. Her predecessor, Miss Chandler, had never once made use of that map, which was older than our fathers, and until that70 moment, not a one of us knew it was there.Miss Spivey showed us on the map how she and Dr. Janet Miller had sailed across the Atlantic Ocean and past the Rock of Gibraltar into theMediterranean Sea. Using the end of a ruler, she75 gently tapped such places as Morocco and Tunis and Algiers to mark their route along the top of Africa. They spent twenty hours on the train to Baghdad, she said, swathed in veils against the sand that crept in every crack and crevice.80 "And can you guess what we saw from the train?" Miss Spivey asked. We could not. "Camels!" she said. "We saw a whole caravan of camels." She looked around the room, waiting for us to be amazed and delighted at the thought.85 We all hung there for a minute, thinking hard, until Mavis Davis spoke up."She means like the three kings rode to Bethlehem," Mavis said, and she folded her hands smugly on her seventh-grade desk in the back of the 90 room.Miss Spivey made a mistake right then.

(B)establish a friendly dynamic between the charming schoolchildren and their indulgent and doting new instructor. (C)introduce Ralphord as a precocious young student and Miss Spivey as a dismissive and disinterested teacher. (D)demonstrate that the children want to amuse Miss Spivey with their questions.

In the early 1990s, textbooks acknowledged that humans had slow-conducting nerves, but asserted that those nerves only responded to two types of stimuli: pain and temperature. Sensations of pressureand vibration were believed to travel only along myelinated, fast-signaling nerve fibers, which also give information about location. Experiments blocking nerve fibers supported this notion. Preventing fast fibers from firing (either by clamping 10 the relevant nerve or by injecting the local anesthetic lidocaine) seemed to eliminate the sensation of pressure altogether, but blocking slow fibers only seemed to reduce sensitivity to warmth or a small painful shock.15 Håkan Olausson and his Gothenburg University colleagues Åke Vallbo and Johan Wessberg wondered if slow fibers responsive to gentle pressure might be active in humans as well as in other mammals. In 1993, they corralled 28 young20 volunteers and recorded nerve signals while gently brushing the subjects' arms with their fingertips. Using a technique called microneurography, in which a fine filament is inserted into a single nerve to capture its electrical impulses, the scientists were able25 to measure how quickly-or slowly-the nerves fired. They showed that soft stroking prompted two different signals, one immediate and one delayed. The delay, Olausson explains, means that the signal from a gentle touch on the forearm will30 reach the brain about a half second later. This delay identified nerve impulses traveling at speeds characteristic of slow, unmyelinated fibers-about 1 meter/second-confirming the presence of these fibers in human hairy skin. (In contrast, fast-35 conducting fibers, already known to respond to touch, signal at a rate between 35 and $75 \mathrm{~m} / \mathrm{s}$.)Then, in 1999, the group looked more closely at the characteristics of the slow fibers. They named these "low-threshold" nerves "C-tactile," or CT,40 fibers, said Olausson, because of their "exquisite sensitivity" to slow, gentle tactile stimulation, but unresponsiveness to noxious stimuli like pinpricks.But why exactly humans might have such fibers, which respond only to a narrow range of rather45 subtle stimuli, was initially mystifying. Unlike other types of sensory nerves, CT fibers could be found only in hairy human skin-such as the forearm and thigh. No amount of gentle stroking of hairless skin, such as the palms and soles of the feet, prompted50 similar activity signatures. Olausson and his colleagues decided that these fibers must be conveying a different dimension of sensory information than fast-conducting fibers.Although microneurography can give55 information about how a single nerve responds to gentle brushing and pressure, it cannot tease out what aspect of sensation that fiber relays, says Olausson. He wanted to know if that same slow nerve can distinguish where the brush touches the$60 \mathrm{arm}$, and whether it can discern the difference between a goat-hair brush and a feather. Most importantly, could that same fiber convey a pleasant sensation?To address the question, Olausson's group sought65 out a patient known as G.L. who had an unusual nerve defect. More than 2 decades earlier, she had developed numbness across many parts of her body after taking penicillin to treat a cough and fever. Testing showed that she had lost responsiveness to 70 pressure, and a nerve biopsy confirmed that G.L.'s quick-conducting fibers were gone, resulting in an inability to sense any pokes, prods, or pinpricks below her nose. But she could still sense warmth, suggesting that her slow-conducting unmyelinated 75 fibers were intact.Upon recruiting G.L., Olausson tested her by brushing her arm gently at the speed of between 2-10 centimeters per second. She had more trouble distinguishing the direction or pressure of the brush80 strokes than most subjects, but reported feeling a pleasant sensation. When the researchers tried brushing her palm, where CT fibers are not found, she felt nothing.Olausson used functional MRI studies to examine 85 which areas of the brain lit up when G.L.'s arm was gently brushed to activate CT fibers. In normal subjects, both the somatosensory and insular cortices were activated, but only the insular cortex [which processes emotion] was active when researchers90 brushed G.L.'s arm. This solidified the notion that CT fibers convey a more emotional quality of touch, rather than the conscious aspect that helps us describe what we are sensing. CT fibers, it seemed, specifically provide pleasurable sensationsQ: Based on the passage, textbook authors in the early 1990s would most likely have expected which condition to result from the blocking of fast fibers? Answer Choices: (A)The rate at which other nerve fibers fired would increase. (B)The test subject would perceive gentle stimuli as painful. (C)The body would compensate by using slow fibers to sense pressure. (D)The ability to perceive vibrations would be impaired.

The delay, Olausson explains, means that the signal from a gentle touch on the forearm will30 reach the brain about a half second later. This delay identified nerve impulses traveling at speeds characteristic of slow, unmyelinated fibers-about 1 meter/second-confirming the presence of these fibers in human hairy skin. (In contrast, fast-35 conducting fibers, already known to respond to touch, signal at a rate between 35 and $75 \mathrm{~m} / \mathrm{s}$.)Then, in 1999, the group looked more closely at the characteristics of the slow fibers. They named these "low-threshold" nerves "C-tactile," or CT,40 fibers, said Olausson, because of their "exquisite sensitivity" to slow, gentle tactile stimulation, but unresponsiveness to noxious stimuli like pinpricks.But why exactly humans might have such fibers, which respond only to a narrow range of rather45 subtle stimuli, was initially mystifying. Unlike other types of sensory nerves, CT fibers could be found only in hairy human skin-such as the forearm and thigh. No amount of gentle stroking of hairless skin, such as the palms and soles of the feet, prompted50 similar activity signatures. Olausson and his colleagues decided that these fibers must be conveying a different dimension of sensory information than fast-conducting fibers.Although microneurography can give55 information about how a single nerve responds to gentle brushing and pressure, it cannot tease out what aspect of sensation that fiber relays, says Olausson. He wanted to know if that same slow nerve can distinguish where the brush touches the$60 \mathrm{arm}$, and whether it can discern the difference between a goat-hair brush and a feather. Most importantly, could that same fiber convey a pleasant sensation?To address the question, Olausson's group sought65 out a patient known as G.L. who had an unusual nerve defect. More than 2 decades earlier, she had developed numbness across many parts of her body after taking penicillin to treat a cough and fever. Testing showed that she had lost responsiveness to 70 pressure, and a nerve biopsy confirmed that G.L.'s quick-conducting fibers were gone, resulting in an inability to sense any pokes, prods, or pinpricks below her nose. But she could still sense warmth, suggesting that her slow-conducting unmyelinated 75 fibers were intact.Upon recruiting G.L., Olausson tested her by brushing her arm gently at the speed of between 2-10 centimeters per second. She had more trouble distinguishing the direction or pressure of the brush80 strokes than most subjects, but reported feeling a pleasant sensation. When the researchers tried brushing her palm, where CT fibers are not found, she felt nothing.Olausson used functional MRI studies to examine 85 which areas of the brain lit up when G.L.'s arm was gently brushed to activate CT fibers. In normal subjects, both the somatosensory and insular cortices were activated, but only the insular cortex [which processes emotion] was active when researchers90 brushed G.L.'s arm. This solidified the notion that CT fibers convey a more emotional quality of touch, rather than the conscious aspect that helps us describe what we are sensing. CT fibers, it seemed, specifically provide pleasurable sensationsQ: According to the passage, G.L. differed from Olausson's other test subjects in terms of the Answer Choices: (A)number of cortices activated in the brain during gentle brushing. (B)physical dimensions of the somatosensory cortex. (C)intensity of nerve signals required to activate the insular cortex. (D)effect of MRI scanning on the basic function of brain cortices.

In the early 1990s, textbooks acknowledged that humans had slow-conducting nerves, but asserted that those nerves only responded to two types of stimuli: pain and temperature. Sensations of pressureand vibration were believed to travel only along myelinated, fast-signaling nerve fibers, which also give information about location. Experiments blocking nerve fibers supported this notion. Preventing fast fibers from firing (either by clamping 10 the relevant nerve or by injecting the local anesthetic lidocaine) seemed to eliminate the sensation of pressure altogether, but blocking slow fibers only seemed to reduce sensitivity to warmth or a small painful shock.15 Håkan Olausson and his Gothenburg University colleagues Åke Vallbo and Johan Wessberg wondered if slow fibers responsive to gentle pressure might be active in humans as well as in other mammals. In 1993, they corralled 28 young20 volunteers and recorded nerve signals while gently brushing the subjects' arms with their fingertips. Using a technique called microneurography, in which a fine filament is inserted into a single nerve to capture its electrical impulses, the scientists were able25 to measure how quickly-or slowly-the nerves fired. They showed that soft stroking prompted two different signals, one immediate and one delayed.

Many millennia before the invention of herbicides, farmers simply plowed their fields to control weeds. Even today, plowing can constitute a valuable part of an integrated weed-management 5 program. Although plowing kills standing weeds, farmers have long known that it often leads to the emergence of new weed seedlings in a few weeks.Ecologists have shown that a farmer's field can have 50,000 or more weed seeds per square meter 10 buried beneath the soil surface. Plant physiologists have shown that seeds buried more than about one centimeter below the soil surface do not receive enough light to germinate. Do the blades of a plow, which can reach more than a foot beneath the soil15 surface, bring some of these buried seeds to the surface where their germination is induced by exposure to sunlight?Two ecologists, Jonathan Sauer and Gwendolyn Struik, began to study this question in the 1960s. In a 20 relatively simple experiment, they went to ten different habitats in Wisconsin during the night and collected pairs of soil samples. They stirred up the soil in one sample of each pair in the light and stirred up the other sample of each pair in the dark. They then25 exposed all ten pairs to natural sunlight in a greenhouse. For nine of the ten pairs of soil samples, weed growth was greater in the samples stirred up in light. They concluded that soil disturbance gives weed seeds a "light break," and this stimulates their 30 germination.More recently, Karl Hartmann of Erlangen University in Germany reasoned that when farmers plowed their fields during the day, the buried weed seeds are briefly exposed to sunlight as the soil is35 turned over, and that this stimulates their germination. Although the light exposures from plowing may be less than one millisecond, that can be enough to induce seed germination. Thus the germination of weed seeds would be minimized if40 farmers simply plowed their fields during the night, when the photon fluence rate [the rate at which photons hit the surface] is below $10^{15}$ photons per square meter per second. Although even under these conditions hundreds of millions of photons strike 45 each square millimeter of ground each second, this illumination is below the threshold needed to stimulate the germination of most seeds.Hartmann says that he was very skeptical when he first came up with this idea because he assumed 50 that such a simple method of weed control as plowing at nighttime must be ineffective or it would have been discovered long ago. But the subsequent experiments, first presented at a 1989 scientific meeting in Freiburg, Germany, clearly demonstrated 55 that the method can be effective.Hartmann tested his idea by plowing two agricultural strips near Altershausen, Germany.

No crops were planted in these pilot experiments, to avoid possible competition with the emerging weeds. The results were dramatic. More than 80 percent of the surface of the field plowed in daylight was covered by weeds, whereas 65 only about 2 percent of the field plowed at night was covered by weeds.This method of weed control is currently being used by several farmers in Germany.

Many millennia before the invention of herbicides, farmers simply plowed their fields to control weeds. Even today, plowing can constitute a valuable part of an integrated weed-management 5 program. Although plowing kills standing weeds, farmers have long known that it often leads to the emergence of new weed seedlings in a few weeks.Ecologists have shown that a farmer's field can have 50,000 or more weed seeds per square meter 10 buried beneath the soil surface. Plant physiologists have shown that seeds buried more than about one centimeter below the soil surface do not receive enough light to germinate. Do the blades of a plow, which can reach more than a foot beneath the soil15 surface, bring some of these buried seeds to the surface where their germination is induced by exposure to sunlight?Two ecologists, Jonathan Sauer and Gwendolyn Struik, began to study this question in the 1960s. In a 20 relatively simple experiment, they went to ten different habitats in Wisconsin during the night and collected pairs of soil samples. They stirred up the soil in one sample of each pair in the light and stirred up the other sample of each pair in the dark. They then25 exposed all ten pairs to natural sunlight in a greenhouse. For nine of the ten pairs of soil samples, weed growth was greater in the samples stirred up in light. They concluded that soil disturbance gives weed seeds a "light break," and this stimulates their 30 germination.More recently, Karl Hartmann of Erlangen University in Germany reasoned that when farmers plowed their fields during the day, the buried weed seeds are briefly exposed to sunlight as the soil is35 turned over, and that this stimulates their germination. Although the light exposures from plowing may be less than one millisecond, that can be enough to induce seed germination. Thus the germination of weed seeds would be minimized if40 farmers simply plowed their fields during the night, when the photon fluence rate [the rate at which photons hit the surface] is below $10^{15}$ photons per square meter per second.

Lady Carlotta stepped out on to the platform of the small wayside station and took a turn or two up and down its uninteresting length, to kill time till the train should be pleased to proceed on its way. Then,in the roadway beyond, she saw a horse struggling with a more than ample load, and a carter of the sort that seems to bear a sullen hatred against the animal that helps him to earn a living. Lady Carlotta promptly betook her to the roadway, and put rather a 10 different complexion on the struggle. Certain of her acquaintances were wont to give her plentiful admonition as to the undesirability of interfering on behalf of a distressed animal, such interference being "none of her business." Only once had she put the 1 doctrine of non-interference into practice, when one of its most eloquent exponents had been besieged for nearly three hours in a small and extremely uncomfortable may-tree by an angry boar-pig, while Lady Carlotta, on the other side of the fence, had20 proceeded with the water-colour sketch she was engaged on, and refused to interfere between the boar and his prisoner. It is to be feared that she lost the friendship of the ultimately rescued lady. On this occasion she merely lost the train, which gave way to 25 the first sign of impatience it had shown throughout the journey, and steamed off without her. She bore the desertion with philosophical indifference; her friends and relations were thoroughly well used to the fact of her luggage arriving without her.30 She wired a vague non-committal message to her destination to say that she was coming on "by another train." Before she had time to think what her next move might be she was confronted by an imposingly attired lady, who seemed to be taking a 35 prolonged mental inventory of her clothes and looks."You must be Miss Hope, the governess I've come to meet," said the apparition, in a tone that admitted of very little argument."Very well, if I must I must," said Lady Carlotta to 40 herself with dangerous meekness."I am Mrs. Quabarl," continued the lady; "and where, pray, is your luggage?""It's gone astray," said the alleged governess, falling in with the excellent rule of life that the absent 45 are always to blame; the luggage had, in point of fact, behaved with perfect correctitude. "I've just telegraphed about it," she added, with a nearer approach to truth."How provoking," said Mrs. Quabarl; "these 50 railway companies are so careless. However, my maid can lend you things for the night," and she led the way to her car.During the drive to the Quabarl mansion Lady Carlotta was impressively introduced to the 55 nature of the charge that had been thrust upon her; she learned that Claude and Wilfrid were delicate, sensitive young people, that Irene had the artistic temperament highly developed, and that Viola was something or other else of a mould equally60 commonplace among children of that class and type in the twentieth century."I wish them not only to be TAUGHT," said Mrs. Quabarl, "but INTERESTED in what they learn. In their history lessons, for instance, you must try to65 make them feel that they are being introduced to the life-stories of men and women who really lived, not merely committing a mass of names and dates to memory. French, of course, I shall expect you to talk at meal-times several days in the week."70 "I shall talk French four days of the week and Russian in the remaining three.""Russian? My dear Miss Hope, no one in the house speaks or understands Russian.""That will not embarrass me in the least," said 75 Lady Carlotta coldly.Mrs. Quabarl, to use a colloquial expression, was knocked off her perch. She was one of those imperfectly self-assured individuals who are magnificent and autocratic as long as they are not80 seriously opposed. The least show of unexpected resistance goes a long way towards rendering them cowed and apologetic. When the new governess failed to express wondering admiration of the large newly-purchased and expensive car, and lightly85 alluded to the superior advantages of one or two makes which had just been put on the market, the discomfiture of her patroness became almost abject. Her feelings were those which might have animated a general of ancient warfaring days, on beholding his 90 heaviest battle-elephant ignominiously driven off the field by slingers and javelin throwers.Q: Which choice best summarizes the passage? Answer Choices: (A)A woman weighs the positive and negative aspects of accepting a new job. (B)A woman does not correct a stranger who mistakes her for someone else. (C)A woman impersonates someone else to seek revenge on an acquaintance. (D)A woman takes an immediate dislike to her new employer.
