Read the following article and select the best answer. Article: From James Dean to Growing Pains, Hollywood has long had a love affair with the relationship between teens and their parents. As the fascination with this relationship attests, parents play a crucial role in the development of their children's personalities. Teenagers learn by closely observing what people around them do. Parents are literally their first teachers and serve as role models. From hygiene to habits, from time management to personal manner, parents form the foundation of their children's characteristics. These tiny individual factors on our everyday behavior collectively constitute who we are. A second influence occurs at the spiritual level. Parental treatment of children is reflected in children's relationship with others. For example, my dad was quite angry with my study habits a few years back and lost his temper.I clearly remember that I too would easily lose my cool and shout at people, often saying things I later regretted, in those difficult days. Parents of my fellow classmates often tend to be anxious about the studies of their children, which can lead to a lack of confidence in their children. If we are boats weathering a storm as we navigate toward maturity, then parents should be our captains. It is as easy to lead us to shipwreck as is to take us ashore safely. To be fair, the guidance and influence of our parents are not the sole factors in molding us. There are numerous examples of teens forging their own paths and becoming something of which their parents never dreamed. Even so, parents must be a fundamental force that positively influences their children. At their best, they can help to solve teenage problems with a respect for their children's thoughts. Question: We can conclude from the passage that _ . - teens will always be what their parents expect them to - parents' behavior influences their children both physically and mentally - the guidance and influence of parents are the only factor in molding teens - parents should be our captains when we teens are on boats in a storm
(Answer)
parents' behavior influences their children both physically and mentally

Read the following article and select the best answer. Article: Albert Einstein died long ago. However, a group of researchers have created a robot which looks like the great scientist. The robotic Einstein is very special because the researchers at the University of California, San Diego (UCSD) have taught their realistic robot to smile, frown and make other complex facial expressions. Scientists believe that babies learn to control their bodies through movements, including learning to speak. "We use the same idea to work out the problem of how a robot could learn to make realistic facial expressions," said Javier Movellan, director of UCSD's machine Feeling Lab. ks5u The San Diego researchers directed the Einstein robot's head to turn in all directions. The robot could see its expressions in a mirror and then use the software to provide data for machine-learning to match facial expressions to the movements of its small motors. Once the robot learned the relationship between facial expressions and the muscle movements, it learned to make facial expressions. Its head has about 30 facial feelings, and each is moved by a tiny motor connected to ht e skin by s sting. Although we've never met Albert Einstein, we have a feeling that the new robot isn't exactly a fair representation of now of the best minds of the 20th century. The figure does not have the grace of the great man, but it can recognize human expressions and react to them in the right way. In fact, if you smile at it, it will smile right back to you. "As far as we know, no other research group has used a robot to make realistic facial expressions," said computer scientist Tingfan Wu, a computer science PhD student who worked on a more exact facial expression robot. Question: How does the robotic Einstein make the muscle movements?. - Some software directs tiny motors to do it. - It begins to do that after learning how to smile. - The researchers move its muscles up and down. - It learns to do that only with a mirror.
(Answer)
Some software directs tiny motors to do it.

Read the following article and select the best answer. Article: At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim immediately when it's sunny and brighten when a passing cloud blocks the sun. A wall of windows at a University of Pennsylvania engineering building has built-in blinds controlled by a computer program that follows the sun's path. Buildings are getting smarter and the next generation of building materials is expected to do even more. Windows could catch the sun's energy to heat water. Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up. Many new materials and technology have been designed in the last 15 years. They are now being used in a wave of buildings designed to save as much energy as possible. They include old ideas, like "green roofs", where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out. As technologies such as sensors become cheaper, their uses spread. The elevators at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floors into the same elevator, thus saving elevator stops. People who work in the building will enter it by swiping ID cards that will tell the elevators their floor, readouts will then tell them which elevator to use. The building also has windows with a coating that blocks heat while letting in light. More new building materials and technology are in development. A Philadelphia building firm is now working on "smart wrap" that uses tiny solar collectors to catch the sun's energy and transmitters as wide as a human hair to move it. They are expected to change the face of the construction industry in the next ten years or so. Question: _ will be developed and used in the construction industry. - "Green roofs" that cool or heat buildings - "Smart wrap" that catches the sun's energy - Sunlight-measuring sensors that control lights - Window coating that lets light in, but keeps heat out
(Answer)
"Smart wrap" that catches the sun's energy
