I'm taking a test and have to guess the right answer to the question after the article. Article: WASHINGTON, March 14 (Xinhua) --U.S. President Barack Obama confirmed on Saturday at the White House that China can have confidence in the American economy. "Not just the Chinese government, but every investor can have absolute confidence in the _ of investments in the United States," Obama said.

S. will push for stricter regulation of the financial industry "front and center" at the upcoming Group of 20Summit in London ,ending an argument between the Europe and the United States over whether more focus should be placed on financial regulatory reform. Chinese Premier Wen Jiabao said earlier Friady he is "a little bit worried "about the safety of Chineseassets in the United States ,urging the U. S. government to ensure the security of those assets. China has invested its hugeforeign exchangereserves in low-risk but low-yield assets ,such as U. S.government bonds ,to play it safe . According to the U.S. Treasury, China held 681.9 billion U.S. dollars worth of U.S. government bonds as of November. "China is indeed the largest creditor of the United States, which is the world' s biggest economy .We are extremely interested in developments in the U.

Question: It can most likely be inferred from the passage that _ . Options: A: the U. S. is now having great difficulty improving the economy. B: China will have confidence in Obama forever according to Wen's speech C: China held 681.9 billion U.S. dollars worth of U.S.government bonds as of November D: China will do its best to help the U.S. overcome the global financial crisis.

I'm taking a test and have to guess the right answer to the question after the article. Article: When I was about 12, I had an enemy, a girl who liked to point out my shortcomings. Week by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes. He listened to me quietly, then he asked. "Are the things she says true or not? Janet, didn't you ever wonder what you're really like ? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said." I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could--and suddenly I wanted to change. For the first time I go to fairly clear picture of myself. I brought the list back to Daddy. He refused to take it."That's just for you," he said."You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do." Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice. Question: Why did her father listen to her quietly? Options: A: Because he believed that what her daughter's "enemy" said was mostly true. B: Because he had been so angry with his daughter's shortcomings that he wanted to show this by keeping silent for a while. C: Because he knew that his daughter would not listen to him at that moment. D: Because he wasn't quite sure which girl was telling the truth.

I'm taking a test and have to guess the right answer to the question after the article. Article: With petroleum reserves decreasing,the search is on to replace gas with a cleaner,greener alternative.Though much eco-talk has centered on biofuels from corn and soybeans,the biofuel that looks more likely to replace petroleum comes from a most unlikely source:algae . Algae,like corn,soybeans,and other crops,grow via photosynthesis and can be processed into fuel oil.However,they _ 30 times more energy than land crops such as soybeans,according to the U.S.Department of Energy.Many algae species also can grow in saltwater and polluted water-while corn and soy require arable land and fresh water that will be in short supply as the world's population balloons. "If you replaced all the diesel in the U.S.with soy biodiesel,it would take half the land mass of the U.S.to grow those soybeans,"says Matt Caspari,chief executive of Aurora Biofuels,a Berkeley,Calif.-based private firm that specializes in algae oil technology.On the other hand,the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States,it would require 15,000 square miles,which is a few thousand miles larger that Maryland (12,407 square miles),the 42nd state in land area. Another bonus:Because algae can be grown just about anywhere in a closed space,they 're being tested at several power plants across the nation as a carbon absorber.Smokestack emissions can be pumped directly into the ponds,feeding the algae while keeping greenhouse gases out of the atmosphere. Although processing technology for algae fuel--also known as "oilgae" in some environmentalist circles--is improving,it's still years away from reaching your local gas pump."It's just a question of cost,because no large-scale facilities have been built yet," Caspari says. Question: Compared with corn and soybeans,algae _ . Options: A: may pollute water and soil B: can grow in poor conditions C: provide much less energy D: need more special care
