Question: Article: Fish have ears. Really. They're quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths. As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate . By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish's age, just like the growth rings of a tree. Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They're examining the chemical elements of each otolith ring. The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring. Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history. In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles. This is important to managers in the fish industry, who know nearly nothing about the track of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears. Question: What can we learn about fish ears from the text? Yes or no, is the answer "They are not seen from the outside."?
Answer: No

Question: Article: "China is expected to complete its first exploration of the moon in 2010 and will found a moon base just as we did on the North and South Poles," Ouyang Ziyuan, head of China's moon exploration program, promised during national science and technology week. After its first man in space, China plans a space laboratory, a lunar orbiter to look for valuable elements and minerals, robot landings on the moon and then the human touchdown. The price of space exploration is enormous. Russia and the US, the only two countries to have achieved manned flight, are struggling to keep their new investment, the international space station. But China, which has a long tradition in physics, mathematics and engineering, finds its doctoral graduates welcomed in the US and Europe for decades. And it has been able to learn from 40 years of pioneering successes and mistakes by the USSR and the USA. Space flight is a gamble and the stakes are high. If successful, China could become a member of the world's most exclusive club, set up a second home on the moon and get a powerful hand at the strategic bargaining table. Two designers from the Shenzhou III project said that 12 astronauts now are undergoing intensive training. One more unmanned space flight is planned before the first manned launch. Experts say that the Shenzhou spacecraft already provides China with a space vehicle capable of mounting a lunar program. Chinese scientists have also predicted that Mars will be the next target after the moon. Question: Which one of the following is NOT right according to this passage? Yes or no, is the answer "China's first man has landed the moon in space."?
Answer: No

Question: Article: ohn Cruitt, 62, spent decades tracking down his third- grade teacher. He wanted to talk with Cecile Doyle about 1958--- the year his mother, who was seriously ill, passed away. Her death came just days before Christmas. Cruitt had been expecting to go home from school and decorate the Christmas tree. "When I found out she died, I could certainly relate to that, because when I was 11, my own father died," Doyle tells Cruitt at StoryCorps in Monroe, N.Y. "And you just don't know how you're going to go on without that person." When Cruitt returned to school, Doyle waited until all of the other children left the room at the end of the day, and told him that she was there if he needed her. "Then you kissed me on the head," Cruitt says. "And I felt that things really would be OK." "Well, Cruitt, I'm so glad that I could be there with you for that time," says Doyle, 82. Decades after his mother's death, Cruitt began to think more and more of Doyle. He finally wrote a letter: Dear Mrs. Doyle, If you are not the Cecile Doyle who taught English at Emerson School in Kearny, N.J., then I'm embarrassed, and you can disregard the letter. My name is John Cruitt, and I was in your third- grade class during the 1958-1959 school year. Two days before Christmas, my mother passed away, and you told me that you were there if I needed you. I hope life has been as kind to you as you were to me. God bless you. John Cruitt Doyle says his letter, which arrived in February, could not have come at a better time. Her husband, who passed away this August, was struggling with Parkinson's disease. "And I had just come home from the hospital, and I read this beautiful letter, and I just was overwhelmed," she says. "Well the funny thing is, when I finally wrote to you again after 54 years, I typed the letter--- I was afraid my penmanship wasn't going to meet your standards," Cruitt says as Doyle laughs. "John, what can I say--- I'm just glad that we made a difference in each other's life." Question: Before Cruitt wrote the letter, he _ . Yes or no, is the answer "was unsure whether Doyle could receive the letter"?
Answer:
No
