Read the following article and select the best answer. Article: In any family with more than one child, chidren seem to naturally compete for their parents' love and attention. Parents say they love every child equally. But is that true? Susan, founder of a consulting firm in Chicago, interviewed 216 women and found that even though none of her questions asked directly about a parent favoring one child over another, about two-thirds of the women said there was a favored child. And they also remembered their experience when they were young. One of the women said, "My mother always liked my brother better, and he got to go to summer camp in 1968 and I didn't." Plumez, who interviewed parents with both biological children and adoptive children for an adoption book in 2008, found that what matters most is whether your temperaments are pleasing. "In some cases, parents would say they felt closer to their adopted children," she says, "Some parents like the children with characters similar to theirs. Two people who are shy and withdrawn might get along well, unless the shy parent doesn't like that aspect of themselves and they try to push the naturally withdrawn child to be more ." It could be a result of gender, birth order or how easy or difficult a child's temperament may be, but a parent's different treatment has far-reaching effects. Students have found that less-favored children may suffer emotionally, with decreased self-esteem and behavioral problems in childhood. Favoritism is a reason for the next generation not to like each other. Experts say it is not realistic to say everyone should be treated equally, because no two people are the same and they relate differently to others. "It does not mean that parent loves or likes one child more. It has to do with which one of them is independent," says psychologist Laurie Kramer of the University of Illinois. Question: What is the best title for the passage? - Parents' favoritism can affect children deeply - Why do parents show favoritism to children? - Parents should give attention to all their children - Building a harmonious family is important to children
Parents' favoritism can affect children deeply

Read the following article and select the best answer. Article: We all enjoy the beautiful show of color1s as leaves change each autumn. But did you ever wonder how and why this happens? To answer the question, first you have to understand what leaves are and what they do. Leaves are nature's food factories. Plants take water from the ground through their roots. And they take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose . Glucose is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis . That means, "putting together with light". A chemical called chlorophyll helps photosynthesis. Chlorophyll is what gives plants their green color1. As summer ends and autumn comes, the days get shorter and shorter. This is how trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange leaves. Small amounts of these color1s have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll. The bright reds and yellows we see in leaves are made mostly in autumn. In some trees, like maples, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color1. The brown color1 of trees like oaks is made from waste left in the leaves. It is the mixture of all these things that makes the beautiful color1s we enjoy during autumn. Question: Which of the following about chlorophyll is NOT true? - Without it photosynthesis couldn't happen. - It is the reason why leaves have their green color1. - It turns the leaves red during autumn. - It is a chemical that's important for trees' food making.
It turns the leaves red during autumn.

Read the following article and select the best answer. Article: The robot moved into the fighting ring with confidence.Then it turned around quickly and knocked itself over. The team of Scouts that built the 8-inch -tall machine immediately realized one arm was too long.They would have to work fast---practice time was over , and the real robot matches were about to begin . "We tried to fix it , but by that time , the other teams had more advanced technology ," says Eagle Scout Matthew Patchen , 16. "They were a couple of steps ahead of us ." In the end , Matthew's team didn't win the robot competition . But they had a great time working on their Robotics merit badges at the 2011 Advance Camp in Antioch , Calif . Advance Camp is held the last Saturday in September at the Contra Costa County Fairgrounds in Antioch, Calif.Nearly 1,500 Scouts attended in 2011 and worked on different merit badges .Scouts choose from more than 50 merit -badge classes taught by counselors .They can earn merit badges from Fingerprinting to Nuclear Science to Swimming .Robotics is the most popular class . First , one of the counselors talked to Matthew and the other Scouts in his Robotic class about the many different uses for robots . "I learned how advanced it really is ," Matthew says . "Robots are used in medicine and industry ." After the talk , the Scouts were divided into five-person teams . Each team was required to build a basic robot . The next step was programming the tiny computer in the robot so it would make the right moves once it was in the ring . "We programmed our robot so its arm was moving all the time ," Matthew says . "That way , it would knock the other robot over." . That's when they discovered the arm on their robot was too long . As a result , their robot knocked itself over before it could fight with any other robots . "It was a learning experience ," Matthew says . "You have to think ahead."
