Although video game sales have increased steadily over the past 3 years, we can expect a reversal of this trendin the very near future. Historically, over three quartersof video games sold have been purchased by peoplefrom 13 to 16 years of age, and the number of people in this age group is expected to decline steadily overthe next 10 years. Which one of the following, if true, would most seriously weaken the argument?

• Most people 17 years old or older have never purchased a video game
• Video game rentals have declined over the past 3 years
• Most of the people who have purchased video games over the past 3 years are over the age of 16
• New technology will undoubtedly make entirely new entertainment options available over the next 10 years

Driver: My friends say I will one day have an accident because I drive my sports car recklessly. But I have done some research, and apparentlyminivans and larger sedans have very low accident rates compared to sports cars. So trading my sports car in for a minivan would lower my risk of having an accident. The reasoning in the driver’s argument is mostvulnerable to criticism on the grounds that this argument:

• infers a cause from a mere correlation
• relies on a sample that is too narrow
• misinterprets evidence that a result is likely as evidence that the result is certain
• relies on a source that is probably not accurate

Brie, who owns a car dealership, has donated cars to driver education programs at area schools for over five years. She found the statistics on car accidents to be disturbing, and she wanted to do something to encourage better driving in young drivers. Some members of the community have shown their support for this action by purchasing cars from Brie's dealership. Which one of the following propositions is best illustrated by the passage?

• The only way to reduce traffic accidents is through driver education programs
• Altruistic actions sometimes have positive consequences for those who perform them
• Young drivers are the group most likely to benefit from driver education programs.
• It is usually in one’s best interest to perform actions that benefit others

Feathers recently taken from seabirds stuffed and preserved in the 1880s have been found to contain only half as much mercury as feathers recently taken from living birds of the same species. Since mercury that accumulates in a seabird’s feathers as the feathers grow is derived from fish eaten by the bird, these results indicate that mercury levels in saltwater fish are higher now than they were 100 years ago. The argument depends on assuming that

• the amount of mercury in a saltwater fish depends on the amount of pollution in the ocean habitat of the fish
• mercury derived from fish is essential for the normal growth of a seabird’s feathers
• the stuffed seabirds whose feathers were tested for mercury were not fully grown
• the process used to preserve birds in the 1880s did not substantially decrease the amount of mercury in the birds’ feathers
