Article: While I was on a trip to Papua New Guinea to take underwater photographs, I asked a local dive guide to help me find a pygmy sea horse . I wanted to take a picture of it. These sea horses can be red or yellow-and-orange. The red pygmy sea horse lives on only one type of coral, a red sea fan that grows at depths below ninety feet. This depth made the job even tougher. As the pressure on my body increased, I had to breathe harder, which used my air supply faster. So the deeper I dived, the shorter my time underwater. I had a lot to do. First, I had to find the pygmy sea horse's special type of fan .Then I had to look over the whole fan with my magnifying glass to see if a sea horse lived on it. If not, I had to find another fan--all the while keeping an eye on my oxygen supply. The second fan rewarded me with a find. The dive guide held the magnifying glass so I could have my first look at the tiny fish. My next challenge was to focus my camera on such a small subject. The dive guide pointed at the tiny creature. I looked through the viewfinder on my large underwater camera housing , found the guide's finger, and followed it to the sea horse. It was hard to hold ourselves steady because both of us were floating in mid-water, but our system worked. I could hardly contain my excitement as I focused on the eyes of the cutest sea horse imaginable. Question: Why did the author write the passage? Yes or no, is the answer "To show us how she took pictures of a sea horse."?
No

Article: Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age. People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind. Many experts are so convinced of the benefits of challenging in the brain that they are putting the theory to work in their own lives. "The idea is not necessarily to learn to memorize large amounts of information," says James Fozard, associate director of the National Institute of Ageing. "Most of us don't need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness." Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work. Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. "The point is, you need to do both," Cohen says. Intellectual activity actually influences brain-cell health and size. Question: What is the passage mainly about? Yes or no, is the answer "The importance of mental activities in the efficiency of the brain."?
No

Q: Article: It is really a happy thing to look back on the days I spent with Jennie. We met in night school. After Jennie and I had completed the required courses, we started teaching in the same school. For a time we were just casual friends, but one day, when I was telling Jennie about my problem son, we discovered we were kindred spirits. "He's a difficult little character," I explained. Jennie looked thoughtful. "Maybe you're only seeing him with your eyes." She was silent for a moment and then added softly, "It is only with the heart that one sees rightly." I stared at her. "You're quoting that! It's from The Little Prince, Saint-Exupery's book for children, one of my favorites. You know it, too?" Jennie nodded. "I love it. I've read it so often. I've practically memorized it." Now, when I think of Jennie, I recall that book because Jennie --more than anyone I know --possessed the gift of seeing with the heart. From that moment of a treasured book shared, our friendship grew steadily. It wasn't that I didn't have an excellent relationship with my husband and son, but my mother had died shortly after my marriage, and I had neither sisters nor daughters. I realize, now, how I needed someone to share those little, seemingly unimportant things that add so much to life --things that must be shared to be fully appreciated. And it was Jennie who helped me with my fourth-grade problem child. One day I was at my wit's end. "What he needs is a good beating!" I exploded. "He's probably had plenty of those," Jennie said. "Maybe he just needs sincere praise for anything he does right, and a hug or two each day." I followed this suggestion, and eventually, because of Jennie, I discovered a lovable little boy. Looking back, I have to admit that she taught me so much. The days I spent with her has become one of my happiest memories. Question: We learn from the text that _ . Yes or no, is the answer "the author seldom praised her son in the past"?
A: No

Article: These days, it's easy to fly across oceans for vacation. Centuries ago, however, crossing the open seas required thorough and accurate planning, handmade boats, and courage. Scientists and historians have long been looking for clues to explain who crossed which oceans first. When it comes to the trip between Polynesia and South America, chickens may have been among the first ocean voyagers, according to new evidence. After studying an ancient chicken bone, anthropologists from the University of Auckland in New Zealand now say that people and chickens traveled from Polynesia to what is now Chile by about 620 years ago. By then, the Inca people were already living in South America, but the Polynesians would have been the first to get there by sea. Previous theories claimed that European explorers and their chickens sailed to South America first -- but those voyagers didn't arrive until about a century later. In 2002, archaeologists dug up 50 chicken bones from a site in Chile called El Arenal. The team from New Zealand analyzed one to these bones. According to their calculations, the bone is about 650 years old. The researchers also compared the genetic material, or DNA, from the South American chicken bone with DNA from 11 chicken bones that had been found on the Polynesian islands of Tonga and American Samoa. These islands are 6,000 miles west of Chile. The bones found on the Polynesian islands are been 600 and 2,000 years old. Results of the comparisons showed that the chicken bones from both the Polynesian and South American sites had part of DNA in common. The researchers found the same part of DNA in feathers of two living chickens in Chile that belong to a modem breed that lays blue eggs. That DNA evidence suggests a close relationship among the chickens. "However, the weight of scientific evidence is now behind the hypothesis that it was seafaring ( ) Polynesians who sailed from the islands to South America and returned," says archaeologist Patrick V. Kirch of the University of... Question: What do we learn from the passage? Yes or no, is the answer "Before the Polynesians arrived in South America, the Inca people had lived there."?
