Article: Mail was usually carried west on ships that sailed around the bottom of South America and then north to California.That could take several months. So, in eighteen fifty-seven, D.C.Lawmakers in Congress in Washington wanted to make it possible to send mail all the way across the United States by land.Congress offered to help any company that would try to deliver mail overland to the West Coast. A man named John Butterfield accepted this offer. He developed plans for a company that would carry the mail--and passengers, too. Congress gave John Butterfield six hundred thousand dollars to start his company. In return, he had to promise that the mail would travel from Saint Louis, Missouri, to San Francisco, California, in twenty-five days or less. It was not possible to travel straight through because of the Rocky Mountains and the deep snow that fell in winter. So the stagecoach would travel south from Saint Louis to El Paso, Texas, then over to southern California, then north to San Francisco. The distance was about four thousand five hundred kilometers. Two hundred of these stations were built, each about thirty-two kilometers apart. The workers were to quickly change the horses or mules whenever a stagecoach reached the station. There could be no delay. Each stagecoach was to travel nearly two hundred kilometers a day. One hundred stagecoaches were built and painted red or dark green. They were the most modern coaches that money could buy. They were designed to hold as many as nine passengers and twelve thousand pieces of mail. The seats inside could be folded down to make beds. Passengers either slept on them or on the bags of mail. The cost would be one hundred fifty dollars to travel from Saint Louis to San Francisco. If a passenger was not going all the way, the cost was about ten cents a kilometer. The passengers had to buy their own food at the stations. The stagecoach would stop for forty minutes, two times a day. The company warned passengers about the possible dangers. A poster said: "You will... Question: As is described in the passage, the stagecoach _ . Yes or no, is the answer "had different horses or mules pulled all the way"?
No

Article: "Eat local." It's one way to reduce human effect on the planet.Eating local means to try to buy and consume foods that are grown in places close to home.However, most of the food sold at supermarkets is not locally grown or produced.Trucks and planes deliver these foods from hundreds or thousands of miles away.During the transportation, greenhouse gases are produced, causing global warming.So the shorter the distance your foods must travel, the less the harm is done to the environment. But how do you get local food if you live in a large city, hundreds of miles away from farms?Environmental health scientist Dickson Despommier and his students came up with the idea of a "vertical farm". A vertical farm is a glass-walled structure that could be built as tall as a skyscraper.Since the garden is built upwards, rather than outwards, it requires much less space than an ordinary farm.The world is quickly running out of room for ordinary farming.Vertical farms could be a key to this situation.Despommier imagines a 30-story building with a greenhouse on every floor.The walls of the building would be clear, to allow crops to get as much sunlight as possible.Depending on a city's water resources, Despommier thinks hydroponic farming is another method for the vertical farm which needs no soil to grow plants. Despommier says the hydroponic greenhouses would use a system that would use a city's waste water and fill it with nutrition to make the crops grow.If this method works, it would provide food to a city and save millions of tons of water. The idea of a vertical farm has attracted the attention of government officials around the world.Scott Stringer, a government official from New York City, thinks the city is suitable for the vertical farming."Obviously we don't have much land left for us," Stringer said, "But the sky is the limit in Manhattan." Despommier admits that there is still a lot of work to do to make vertical farms a reality."But I think vertical farming is an idea that can work in a big way." he says. Question: By saying "the sky is the limit in Manhattan", Stringer means _ . Yes or no, is the answer "people can make full use of vertical space of Manhattan"?
No

Q: Article: Mr. Harris used to work in Dover, but then he changed his work, and he and his wife moved to another town. They did not have many friends there, but they soon met a lot of interesting people, and after a few weeks, they often went to dinner or to parties at other people's houses. Then Mrs. Harris said to her husband, "We've been to a lot of other people's houses, and now we must invite them to our house, mustn't we?" "Yes, certainly," answered her husband, "A big party will be the easiest thing, won't it? Then we can start to invite people to dinner in small numbers next month." So Mrs. Harris said, "Yes, I'll invite all our friends here to a big party on 5th December." "How many will that be?" Mr. Harris asked. "Don't invite too many." Mrs. Harris was beginning to write the invitations when her husband saw that she was writing, "Party. 6.30 to 8.30 p.m." "That isn't very nice, is it?" he said. "You're telling our guests that they must go at 8.30." So Mrs. Harris just wrote "Party. 6.30 p.m." A lot of guests came, and they all had a good time, so they did not go home at 8.30. In fact they were still there at mid-night when the door bell rang and a policeman arrived. He said, "You must stop making a noise, because someone has complained." Mr. Harris said he did not want to quarrel with the policeman, so everyone went home. They were sorry to have to go. When Mr. and Mrs. Harris were alone again, she said to him. "That was a surprise, wasn't it? Who complained about the noise?" "I did," Mr Harris answered in a tired voice. Question: Why did Mr. Harris telephone the policeman about the noise? Yes or no, is the answer "He did not want his friends to stay late that night."?
A: No

Article: For many of us, printed books are satisfying in ways beyond the words they contain. Billions of printed books have been published, read and saved in the 600 years since movable type was invented, so why mess with a good things? Sony Electronics is doing just that, betting that readers will be won over by the convenience of readability of its new electronic book devices. Sony's reader, the PRS-505, can hold 160 books in its fixed memory, enough to line the shelves on a good-sized wall in the average American home. The $299 device is about the size of a paperback book, but a half-inch thick and weighs less than a pound. The Sony book reader is revolutionary not only in its storage capacity. The font is highly readable and adjustable by size. Unlike laptop computers, you can put the Sony in your purse, read it in direct sunlight and even bookmark the pages. And you can connect it to your PC to download books. Surprisingly, though the reader has liberated the book from paper, electronic books aren't always a bargain. For example, David Baldacci's "Stone Cold" download retails for $15.19 at the Sony site, while Amazon will deliver a hard copy to your mailbox for $16.19. The Sony reader also lets you store and play or display music. So what's not to like about the Sony? Well, for many _ , a lot. Book lovers like to have, hold and keep their volumes, which don't need charging. You can write notes in the margin1s, and enjoy the ambience they provide on your book shelves. The need for electronic reading devices is likely to grow as more people worried about the billions of tons of paper used for printed material. Many believe the time will come when devices like the Sony reader are as common as printed newspapers and magazines today. Question: What would be the best title for the passage? Yes or no, is the answer "The age of the electronic book reader is coming"?
