Directiоns: Chооse the аppropriаte letter to indicаte the conclusion that can be drawn from each passage. Most Americans think that sport utility vehicles (SUVs) are much safer than sports cars. And it’s true that a 5,000-pound SUV like the Chevrolet TrailBlazer is better at what the automotive industry calls “passive safety”; in other words, in a head-on collision with a car, a vehicle like a Ford Explorer is not going to be the one that’s crushed. However, many cars are much better than SUVs at what the automotive industry calls “active safety.” Midsize cars like the Toyota Camry and subcompact cars like the Volkswagen Jetta are more nimble, so their drivers have the ability to maneuver them to avoid crashes with the Explorers and the TrailBlazers. Being nimble and maneuverable, therefore, is often better than being big. Take, for example, emergency-stopping tests performed on both the TrailBlazer and the two-seater Porsche Boxster convertible. At 60 miles per hour, bringing the TrailBlazer to a sudden stop took about 150 feet and was not accomplished easily, for 5,000 pounds of rubber and steel does not stop that fast without a lot of screeching and bucking. The Boxster, however, can come to a complete stop in about 124 feet, which is a difference of about two car lengths. Obviously, two car lengths can, in many situations, mean the difference between life and death. Perhaps it should come as no surprise, then, that the accident fatality rate for drivers of even some subcompact cars is half that for drivers of SUVs like the Ford Explorer, and drivers of the midsize imports, cars like the Camry and the Honda Accord, have the lowest accident fatality rates of all.

Directiоns: Chооse the аppropriаte аnswer or answers to identify the pattern or patterns in each reading. Boys and girls tend to respond differently when their parents divorce. Boys often express their hurt and frustration in outward ways, tending to become more aggressive and disobedient while the separation and divorce are occurring. Because divorce usually causes boys to lose regular contact with their fathers, the parent with whom they identify most strongly, problems with their mothers very often intensify. Mothers typically react by using either authoritarian or permissive parenting styles with their sons, suggesting that they are either trying to reassert control or have given up trying altogether. Both styles can further erode the mother/son relationship. Girls, on the other hand, usually become less aggressive when their parents divorce. They also tend to become more worried about their schoolwork and more attentive to their chores, suggesting that they are expressing their hurt and frustration inwardly and trying to help by acting more responsibly. As a result, their relationships with their mothers tend to improve. According to one study, around six years after a divorce, mothers and daughters had usually established close, positive relation-ships. However, divorce also seems to produce one negative consequence for daughters: a preoccupation with their relationships with males. Girls with divorced parents are more likely to date and engage in sexual relations at an early age, and they are more likely to get pregnant and have difficult relationships with males during their teenage years.
