  • The argument believes that more people simply have to know about the Dvorak keyboard and they will begin using it.
Question 1:
The argument believes that more people simply have to know about the Dvorak keyboard and they will begin using it. (D) casts the most doubt on the conclusion. If businesses have tried educating employees, but the latter have been reluctant, then simply making the Dvorak more widely known is not going to result in converts, the way the argument assumes it will. (B) does not directly weaken the argument the way (D) does. Sure, people claim they will take a few weeks to learn how to use the keyboard. That is not the same as saying they are unlikely to shift.

While the average American reads only two books per year, researchers have recently concluded that by reading two books per month, people can expect their memorizing capacity to double. The most effective way for Americans to begin to read two books per month—thus increasing their memory capacity—is to support Proposition 75, which will require students to read at least two books per month beginning in 2nd grade and through their senior year of high school.
Which of the following can be most properly drawn, if the statements above are true, about future reading habits and memorization capacity?
A. If Proposition 75 passes, all teen-agers will see a significant increase in their ability to memorize for tests
B. Individuals who read 4 books per month are going to be twice as likely to remember long lists of information as those who only read 2 books per month
C. The kids with the best memories in high school are those who read the most books
D. If Proposition 75 passes, responsible high school students can expect their memories to increase
