Input: Consider Input: Article: Bob Butler lost his legs in a 1965 landmine explosion in Vietnam. He returned home as a war hero. Twenty years later,he proved once again that heroism comes from the heart. Butler was working in his garage in a small town in Arizona on a hot summer day when he heard a woman's screams coming from a nearby house. He rolled his wheelchair toward the house,but the dense bush wouldn't allow him to approach the back door. So he got out of his chair and crawled through the dirt and bushes. "I had to get there,"he says. "It didn't matter how much it hurt." When Butler arrived at the house,he traced the screams to the pool,where a three year old girl,Stephanie,was lying at the bottom. She had been born without arms and had fallen in the water and couldn't swim. Her mother stood over her baby screaming loudly. Butler dove to the bottom of the pool and brought little Stephanie up to the deck. Her face was blue,she had no pulse and she was not breathing. Butler immediately went to work performing CPR to revive her while Stephanie's mother telephoned the fire department. She was told the rescue team was already out on a call .Helplessly,she sobbed and hugged Butler's shoulders. As Butler continued with his CPR,he calmly reassured Stephanie's mother. "Don't worry,"he said. "I was her arms to get out of the pool. It'll be okay. I'm now her lungs. Together we can make it." Seconds later the little girl coughed,regained consciousness and began to cry. As they hugged and rejoiced together,the mother asked Butler how he knew it would be okay. "When my legs were blown off in the war,I was all alone in a field,"he told her." No one was there to help except a little Vietnamese girl. As she struggled to drag me into her village,she whispered in broken English,'It okay. You can live. I be your legs. Together we make it.'" "This was my chance,"he told Stephanie's mom,"to return the favor."
Answer: believed that everything will be OK and he would make it.

Input: Consider Input: Article: Have you ever imagined what the world will be in the near future? A recent study shows that the world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in now. Visible ahead is serious stress involving population, resource and environment. Despite greater food output, people in the world will be poorer in many ways than they are today. For hundred of millions of the extremely poor, the outlook for food and other necessities of life will be no better, for many it will be worse. While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nation, the total national product per head in most less developed countries remains low. The existing gap between the rich and poor nations will further widen. World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase goes to the countries that already have higher per-head food consumption. Meanwhile, per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level. What is worse is that prices for food are expected to double. As a result, many less developed countries will have increasing difficulties meeting energy needs. For the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful. Regional water shortage will become more sever. In the 1970-2100 period population growth will require twice as much water as it does today in nearly half the world. Still greater increases would be needed to improve standards of living. Development of new water supply will become more costly.
Answer: the living standard of the world's population will improve greatly

Output: According to the passage, in 2100 while output of food will be greater, _ .

Input: Consider Input: Article: Mark Twain was a great writer. He was from the USA. He was born in 1835. He was also a famous speaker. He was famous for his sense of humour.

Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he'd better not go there.

After he arrived at the town, Mark Twain stayed in a small hotel near the station. He went into his room, but when he was just about to have a rest, quite a few mosquitoes flew about him. The waiters felt very sorry about that. "I'm very sorry, Mr. Mark Twain. There are too many mosquitoes in our town." One of them said to him.
