Q5:

Exposure to certain chemicals commonly used in elementary schools as cleaners or pesticides causes allergic reactions in some children. Elementary school nurses in Renston report that the proportion of schoolchildren sent to them for treatment of allergic reactions to those chemicals has increased significantly over the past ten years. Therefore, either Renston’s schoolchildren have been exposed to greater quantities of the chemicals, or they are more sensitive to them than schoolchildren were ten years ago.

Which of the following is an assumption on which the argument depends?

The number of school nurses employed by Renston’s elementary schools has not decreased over the past ten years.

Children who are allergic to the chemicals are no more likely than other children to have allergies to other substances.

Children who have allergic reactions to the chemicals are not more likely to be sent to a school nurse now than they were ten years ago.

The chemicals are not commonly used as cleaners or pesticides in houses and apartment buildings in Renston.

Children attending elementary school do not make up a larger proportion of Renston’s population now than they did ten years ago.

Q14:

Certain politicians in the country of Birangi argue that a 50 percent tax on new automobiles would halt the rapid increase of automobiles on Birangi’s roads and thereby slow the deterioration of Birangi’s air quality. Although most experts agree that such a tax would result in fewer Birangians buying new vehicles and gradually reduce the number of automobiles on Birangi’s roads, they contend that it would have little impact on Birangi’s air-quality problem.

Which of the following, if true in Birangi, would most strongly support the experts’ contention about the effect of the proposed automobile tax on Birangi’s air-quality problem?
1. Automobile emissions are the largest single source of air pollution.
2. Some of the proceeds from the new tax would go toward expanding the nonpolluting commuter rail system.
3. Currently, the sales tax on new automobiles is considerably lower than 50 percent.
4. Automobiles become less fuel efficient and therefore contribute more to air pollution as they age.
5. The scrapping of automobiles causes insignificant amounts of air pollution.
