Read the following article and select the best answer. Article: Lisa was running late. Lisa, 25, had a lot to do at work,plus visitors on the way: her parents were coming in for Thanksgiving from her hometown. But as she hurried down the subway stairs, she started to feel uncomfortably warm. By the time she got to the platform, Lisa felt weak and tired-maybe it hadn't been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks. Several yards away, Frank, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying. But when he heard the scream, followed by someone yelling, "Oh, my God, she fell in!" Frank didn't hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. "No! Not you! " his girlfriend screamed after him. She was right to be alarmed. By the time Frank reached Lisa, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station. It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the arms and drag her away from the edge. That was where Lisa briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse. Lisa thought she'd been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn't, and that was when she realized how much pain she was in. Police and fire officials soon arrived, and Frank told the story to an officer. Jennifer said her boyfriend was calm on their 40-minute train ride downtown-just as he had been seconds after the rescue, which made her think about her reaction at the time. "I saw the train coming and I was thinking he was going to die." she explained. Question: What was the most probable cause for Lisa's weakness? - She had run a long way. - She felt hot in the subway. - She had done a lot of work. - She had donated blood the night before.
She had donated blood the night before.

Read the following article and select the best answer. Article: Climbing Mount Everest, the world's highest mountain, just became more challenging. The government of Nepal is telling climbers they cannot leave rubbish on the trails . Each climber will have to come down the mountain with at least 18 pounds of garbage. That's the average amount of rubbish a climber leaves behind on Everest. Officials say climbers are responsible for their own rubbish. "We are not asking climbers to pick up rubbish left by someone else," said Maddhu Sudan Burlakoti, who works for the Nepal Tourism Ministry. "We just want them to bring back what they took up." More than 4,000 people have reached the 29,035-foot mountain top in the past 60 years. Leaving rubbish along the way helps climbers keep their bags light so they have energy to reach the top. "The rubbish problem in Mount Everest is not new," Burlakoti says. "When the people started to climb the mountain, they started to leave their garbage there." They have left behind cans, tents, food wrappers, and equipment. Last year, climbers carried down a total of four tons of rubbish. The new rule came into effect in April of 2014. To make sure it is followed, climbers will have to deposit money before the climb. Once they climb back down the mountain, officials will check climbers at a return camp to make sure they have the required 18 pounds of rubbish. If they do, their money will be returned to them. If they do not, climbers will not receive their deposit and they will not be given a permit the next time they want to climb Everest. The goal is to make sure no more litter will be left on Everest, which has earned the nickname the World's Highest Dustbin. "As we offer Mount Everest to all the people of the world they should take responsibility to clean it," Burlakoti says, "After seeing the results from this, we will extend this rule to other mountains also." Question: Why was a new rule made? - The rubbish problem there suddenly became serious. - Mount Everest was considered to be a big dustbin. - Climbers produced four tons of rubbish last year. - The number of climbers there was beyond control.
(Answer)
Mount Everest was considered to be a big dustbin.

Ques: Read the following article and select the best answer. Article: Three Yale University professors agreed in a discussion that the automobile was what one of them called "Public Health Enemy No. 1 in this century". Besides polluting the air and overcrowding the cities, cars are involved in more than half the disastrous accidents, and they contribute to heart disease "because we won't walk anywhere any more," said Richard Weeinaman, professor of medicine and public health. Speaking of many of those man-made dangers of the automobile, Arthur W. Galson, professor of biology, said it was possible to make a kerosene-burning turbine car that would "lessensmog by a very large factor". But he expressed doubt whether Americans were willing to give up moving about the countryside at 90 miles per hour in a large vehicle. "America seems wedded to the motor car--every family has to have at least two, and one has to be a convertible with 300 horsepower," professor Galson continued. "Is this the way of life that we choose because we treasure these values?" For professor Sears, part of the blame lies with "a society that regards profit as a supreme value, under the illusion that anything that's technically possible is, therefore, morally justified". Professor Sears also called the country's dependence on its modern automobiles "terrible economics" because of the large horsepower used simply "moving one individual to work". But he admitted that Americans have painted themselves into a corner by allowing the national economy to become so dependent on the automobile industry. "The solution," Dr Weeinerman said, "is not finding a less dangerous fuel but a different system of inner city transportation. Because of the increasing use of cars, public transportation has been allowed to wither and grow worse, so that if you can't walk to where you want to go, you have to have a car in most cities," he declared. This, in turn, Dr Weeinerman contended, is responsible for the "arteriosclerosis " of public roads, for the pollution of the inner city and for the middle-class movement to the suburbs. Question: The main idea of the passage is that _ . - Americans are used to travelling by cars - American public transportation is growing worse - American car industry caused disastrous road accidents - American people's health is threatened by automobiles
Ans:
American people's health is threatened by automobiles
