Question: Scientists would like to place a huge mirror in space above the earth. It might be sixty miles wide. It would be used to catch the rays   of the sun. It would direct the sun's rays upon the earth as a child might do to make sunlight dance on the wall with a hand mirror. Why do they want to do this? The sun's rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts   which might come at night and hurt fruit crops. They could melt   dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed. The mirror would be used to   _  . A) reflect   sunlight B) absorb   sunlight C) see what the earth looks like D) see how clouds move
Answer: A

Question: She's not afraid of anything. Snakes? No problem. Walking alone in the dark? Easy. We're not talking about a superhero here -- SM is a 44-year-old mother.  And she's fearless because she happens to be missing part of her brain: the amygdala . Shaped like a pair of almonds sitting in the middle of your brain, the amygdala helps control fear and anxiety. A rare condition called Urbach-Wiethe disease left SM without her amygdala, and seems to have completely erased her sense of fear. To try to understand how the amygdala works, a team of researchers made their efforts to scare SM. They showed her horror movies and took her to the Waverly Hills Sanatorium Haunted House in Kentucky. She pushed out one of the monsters  and laughed. SM said she didn't like snakes, but at a pet store full of poisonous creatures, she kept asking to touch them. When asked to rate her feelings, SM reported feeling surprised or disgusted, but never fearful. "She tends to approach everything she should be avoiding," says Justin Feinstein of the  University of Iowa. This means the amygdala could control deeper urges to approach or avoid danger. Other scientists have a different opinion, though.  "I don't believe you can make a general statement about what the amygdala does by a single case study," Elizabeth Phelps said. In 2002, Phelps published a study on a similar patient with amygdala damage who still showed fear. It may sound like fun to be totally fearless, but we get scared for a good reason. "The nature of fear is survival and the amygdala helps us stay alive by avoiding situations, people, or objects that put our life in danger," Feinstein said. SM was once followed in a park after dark by a man with a knife, and she simply walked away. "It is quite remarkable that she is still alive," said Feinstein. What is Elizabeth Phelps' attitude toward the function of the amygdala based on the research on SM? A) Indifferent B) Supportive C) Disapproving D) Interested
Answer: C

Question: With an overwhelming variety of educational toys and learning tools in the market, you really wonder if these educational products are really beneficial to children. There have been many educational DVDs in the market that promise to stimulate a child's learning and enhance his or her cognitive skills. Parents feel good about buying these products for their children. After all, these educational tools try to do a parent's job of participating in the child's education, especially when the parent can't be present due to his or her busy schedule. Moreover, children seem to love these DVDs that contain pictures, words, and loads of stories. Some DVDs contain fun, sing-along songs or read-aloud words to help the children learn different concepts and words. Although these are fun for the parents and the children, the question that needs to be asked is whether these DVDs are actually beneficial to the child, as they claim to be. Although parents expected "educational" products to give their child some educational advantage, research has shown otherwise. Researchers in a recent study concluded that there was indeed no difference between the language and cognitive ability of the infants who were repeatedly exposed to educational DVDs and those who were not exposed to the DVDs. In fact, contrary to expectations, it was found that babies who were exposed to the DVDs at an earlier age had lower overall language scores at a later age. This suggested a damaging effect of such DVDs on younger children. For several years the American Academy of Pediatrics has recommended that toddlers under age of 24 months or 2 years should not watch videos or television. However, there are many parents who believe these DVDs really help in stimulating the child and keep him or her entertained. While it may work as a great babysitter, it is important to limit activities like video games, computer games, DVDs or TV programs. To promote their children's development and cognitive skills, parents are advised to spend time with their children... Which of the following might be the best title for the passage? A) Do educational DVDs Really Work? B) Are You Prepared for Educational Tools? C) Are You Leading Your Child to the Right path? D) What Should You Do for Your Child's Education?

A
