Article: We have always been interested in the moon. 2000 years ago people already knew it moved around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky. When scientists could use telescopes  to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on Earth. This was because they believed the moon had once been a planet that had been caught in the earth's gravity millions of years earlier. In 1969 moon rocks were finally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information. After years of study, most scientists now think that the moon was once part of Earth. They believe very early in its history, maybe 4 million years ago, something about the size of Mars hit Earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon. In the future, even though our ideas about the moon may change again, we will still be interested in it. Question: Before 1969 most scientists thought the moon was   _  . Yes or no, is the answer "a planet caught by the earth's gravity"?
(A).
No

Article: A little stream   ran down from a high mountain through many villages and forests. Then it reached a desert,"I went through so many difficulties. I should have no problem crossing the desert,"she thought. As she started, she found herself slowly disappearing into the sand. After many tries, she still failed. At this time, a deep voice said,"if a breeze   can cross the desert, so can a river."It was the voice of the desert. But the little stream answered,"that's because a breeze can fly, but I can't." "That's because you can't give up what you are. Let yourself evaporate   into the breeze, and _ can take you across,"said the desert. "Give up what I am now? No! No!"The little stream could not accept this idea. "The breeze can carry the vapor   across the desert and let it leave as rain. The rain will form a river again,"said the desert."And whether you're a river or vapor, your nature   never changes." Hearing this, the little stream went into the open arms of the breeze. It carried her to the next stage   of her life. Question: What is the main idea of the story? Yes or no, is the answer "To succeed, we should change the way we used to be."?
(A).
No

Article: "Who did this?" asked my teacher. Thirty children tried to think about not only what they had done, but also what our teacher might have found out. "Who did this?" she asked again. She never became angry, but she was this time. She held up a piece of broken glass and asked, "Who broke this window?" "Oh, oh," I thought. I was the one who broke the window. I did not do it on purpose  . It was caused by a bad throw of a baseball. Why did it have to be me? If I admitted   it, I would be in a lot of trouble. How would I be able to pay for a big window like that? "My father is going to get angry at me," I thought. I didn't want to raise   my hand, but something much stronger than me pulled it up. "I did it," I said. Then I was silent. It was hard enough saying what I had. My teacher went to one of our bookshelves and took down a book. She then began walking towards my desk. I had never known my teacher to strike   a student, but I feared she was going to start with me. "I know how you like birds," she said as she stood looking down at my face. "Here is the field guide about birds   that you always _ from our school library. It is yours now. We have got a new one for the school. You will not be punished  . But remember, it's only for your honesty." I couldn't believe it! I wasn't being punished and I was getting my own bird field guide, the one that I had been saving up all my money to buy. Question: The writer mainly wants to tell us that   _  . Yes or no, is the answer "he who is honest is wise"?
(A).
