Read the following article and select the best answer. Article: What do astronauts eat in space, and why? How did astronaut food come into being? How do astronauts preserve food for long periods of time in space? NASA(the National Aeronautics and Space Administration) has been researching food for space travel since the 1960's to find the best way of keeping astronauts from going hungry. The research could date from an accident that took place on the first manned Gemini mission in 1965. astronaut John Young managed to sneak a corned beef sandwich onto the Geminni III capsule to eat during its orbit around Earth. To Young's surprise, the sandwich plan did not go as expected; instead the sandwich began to break apart and scatter through the Geminni IIIcapsule. This could have resulted in disaster, since a small piece of food could have stuck in the air vents and other equipment. The sandwich was stuffed into a pocket to avoid the further mess inside the small space capsule This incident caused NASA to enforce strict rules on what types of food can be taken into space. Space food has come a long way since then. During the Gemini period, the astronauts mostly ate cubed, compressed foods high in calories and lightweight. NASA expects a long shelf life for space food. The majority of food taken into space has been dried out or heat-treated. These process and use of sodium , make the food taken into space last longer. Research is ongoing into space food to seek out healthier ways to preserve it. Too much sodium is unhealthy, and can badly change the taste of some foods. Question: What happened to John Young in the Geminni III capsule? - His sandwich went bad as expected - He couldn't eat the sandwich he had bought - His sandwich caused trouble to some equipment - He filled his pocket with the sandwich.
He couldn't eat the sandwich he had bought

Read the following article and select the best answer. Article: A 16-year-old boy finds himself on a boat in the Pacific Ocean after escaping a shipwreck . Even worse, he is left with a huge tiger for company. But he manages to survive after 227 days of fighting against all the hardships of the sea. Pi, the lead character in Oscar-winning Ang Lee's new movie Life of Pi, went through an inspiring journey of growth and self-discovery. So did 19-year-old Suraj Sharma, the Indian actor who plays him. But it was a lucky chance that opened up the opportunity for the new star. Sharma was a regular student who lived with his mathematician parents in Delhi, India. As the director traveled to Mumbai to find his Pi, the teenager went along with his younger brother, who had acted in a couple of movies, to audition . But little did Sharma know that he would end up winning the role from 3, 000 hopefuls. Lee said he saw Pi in Sharma: "Not only does he have a compelling and wise look. He has this rare talent." The director said that in the final round, Sharma gave one of the "most compelling readings we had. In the end, he was in tears." Understandably, Sharma didn't want to _ . "He (Lee) had given me this opportunity. I had to give it my best," Sharma told the Philippine Daily Inquirer. Sharma swam for four or five hours a day until he was completely comfortable with the water. He also worked on his body because he had to first gain weight and then quickly lose weight as the story developed. He even had rats run all over him to prepare for his role. Lee was impressed by the teenager, especially his endurance and patience in staying in a water tank for many hours each day. Sharma was only 16 when Lee signed him. After three years of shooting, Sharma said he had matured with Pi's journey. Question: The passage is intended to introduce _ . - the thrilling escape from a shipwreck - how an Oscar-winning movie attracts audience - a young actor became matured when acting in a movie - the difficulty in winning a role in a movie
(Answer)
a young actor became matured when acting in a movie

Question: Read the following article and select the best answer. Article: Today just as technology changed the face of industry, farmers have undergone an "agricultural revolution". On the farm of today, machines provide all the power. One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power. Another technological advance which is still in the experimental stage is the robot, a real "mechanized hired hand" that will be able to move and, in some ways, think like a human being. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the special barn , then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete... Question: Which of the following statements is true? - Farmers in the future will depend totally on computers. - Both computers and robots have been in use on today's farms. - Farmers mainly use machines on their farms at present. - Farmers can do nothing without the help of computers on today's farms.
Answer:
Farmers mainly use machines on their farms at present.
