Q: I'm taking a test and have to guess the right answer to the question after the article. Article: If you have a watch, don't go to a watchmaker's unless something is wrong with the machinery. Once I had a beautiful watch. And it had kept perfect time. But one night it happened that I forgot to _ it _ . Next morning I went to a watchmaker as I wanted my perfect watch to be set by the exact time. He examined it and said, "The regulator must be pushed up as your watch is four minutes slow. I tried to stop him from doing so, but he didn't listen and pushed the regulator. My beautiful watch began to gain. It gained faster and faster day by day. By the end of the second month it had left all the clocks and watches of the town far behind. I could do nothing but take it to another watchmaker to be regulated. I expected him to regulate the watch at once, but he asked me to come in a week's time. When at last I got my watch back from him, it began to slow down. And I failed to be in time for trains, business affairs, and even missed my dinners. Now I went to a third watchmaker. When I was waiting for him to repair my poor watch, he took it to pieces and said that he would try to finish this work in three or four days. What I could do was to nod my head. After that, my watch went for half a day, and then stopped. So I kept taking my watch from one watchmaker to another. But each watchmaker disappointed me. My watch had cost me two hundred dollars, but I paid for repairs more than two hundred. At last I decided to buy another watch, which I did. Question: The writer took his watch to the first watchmaker in order to _ . Options: A: check it whether it kept good time B: change some parts C: have it set by the exact time D: push up the regulator
A: C

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: WHY do we sometimes struggle with moral dilemmas? Why is it a crime to take certain drugs but it's acceptable to take others? Why is it wrong to create human embryos to cure diseases suffered by millions? Often, we follow rules that bring little benefit and can even be positively harmful. But the rules are not set in stone, so there is nothing to stop us getting rid of those that don't work and putting better ones in their place. Now an experiment suggests that morality isn't entirely about benefits to individuals. We also tend to make and obey arbitrary moral rules, probably as a way of promoting social consolidation . A classic psychology experiment called "trolley experiment" suggests that our minds have two moral systems, and they don't always agree. In the trolley experiment, participants are told that an out-of-control trolley could kill five people on the tracks. They must decide whether to turn it onto a second track with only one person on it. Almost everyone does it, sacrificing one to save five. But if instead you have to push one person off a bridge onto the track to stop the trolley, most people say no. That suggests most of us have a strict rule against killing people directly, even for the greater good. How are such rules formed? Although people with morality appear to _ the act of killing in the bridge experiment, most moral behavior in animals appears focused on outcomes--the death of an individual, say--rather than the death of the majority. When an animal experiences harm to help a , biologists view this as increasing the chances that the animal's genes will survive. Many psychologists think that human moral rules are an extension of this "kin selection". Kurzban of the University of Pennsylvania did the experiment further. Kurzban's team gave volunteers changes of the bridge situation. Volunteers were asked what they would do and whether their actions were morally right. 85% of them said it would be morally wrong to push one person off to save five, whether these people are... Question: According to the passage, the rules of morality are, under some circumstances, _ . Options: A: scientific B: reasonable C: harmful D: flexible
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Plants need green leaves to make food. A plant needs sunlight and carbon dioxide from the air for making food and it also needs water and salts from the soil to make food too. There are certain cells in the leaves which change carbon dioxide and water into sugar. To do this the cells needs energy, which they get from the sunlight. Green leaves make food for the whole plant. A red leaf can make food too because under the red color1ing of the leaf there are food----making cells. There are no leaves which are completely yellow, for they can't make food. The plant makes sugar for its food. In sunlight green leaves make a lot of sugar. The veins can't carry all this sugar away, so the leaves change the sugar into starch , which is kept and so stored in the leaves. At night, the starch changes back to sugar. It is then carried away from the leaves. Some of the sugar is used as food by the plant while the rest is stored as starch. In some plants, food is stored in the roots, in others it is stored in the stem and in leaves, fruits and seeds. Question: To make food, plants need a lot except _ . Options: A: the air B: the soil C: the green leaves D: dead leaves
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: A cobbler passed his time in singing from morning till night; it was wonderful to see, wonderful to hear him; he was more satisfied in making shoes than anyone else. His neighbor, on the contrary, who was rolling in wealth, sang but little, and slept less. He was a banker; when by chance he fell into a sleep at day-break, the cobbler awoke him with his song. The banker complained sadly that God had not made sleep a saleable product, like foods or drinks. Then he visited the cobbler and asked him, "How much a year do you earn, Master Gregory?" "How much a year, sir?" said the merry cobbler laughing, "I never count my income in that way, living as what I like from one day to another; somehow I manage to make the ends meet throughout the year; each day brings its meals." "Well then! How much a day do you earn, my friend?" asked the banker continuously. "Sometimes more, sometimes less; but the worst of it is that a number of days occur in the year on which we are forbidden to work, so we won't earn any money during these days, without which our earnings would be better." The banker, who was laughing at the cobbler's simplicity, said that "In the future, I will satisfy what you want. Take the hundred coins, preserve them carefully, and make use of them in time of need." The cobbler was very delighted and fancied that he possessed all the wealth which the earth had produced in the past century for the use of mankind. Returning home, he buried his money and his happiness at the same time. No more singing; he lost his voice. The banker could now have a sound sleep. However, at that moment, the cobbler realized that what he acquired now was the source of sorrow. Sleep broke up with him; and cares, suspicions, and false alarms took its place. All day, his eye wandered in the direction of the treasure, even at night, if some naughty cats made noises, he would think somebody was robbing him. At last, the poor man ran to the house of his rich neighbor; "Give me back," said he, "sleep and my voice, and take your hundred coins." Question: At last, what happened to the cobbler? Options: A: He worried about his money day and night. B: He buried all the money and was very happy. C: He wondered how to use all the money. D: He realized the source of his sadness and returned the money.
A: D
