Q2:

Guidebook writer:  I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward.  Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

 

Which of the following, if true, most seriously weakens the guidebook writer’s argument?

 

A.   The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.

B.    Hotels built since 1930 can generally accommodate more guests than those built before 1930.

C.   The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.

D.   The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.

The average length of apprenticeship(学徒) for carpenters has declined significantly since 1930.

Q8:

When a new restaurant, Martin’s Cafe, opened in Riverville last year, many people predicted that business at the Wildflower Inn, Riverville’s only other restaurant, would suffer from the competition.  Surprisingly, however, in the year since Martin’s Cafe opened, the average number of meals per night served at the Wildflower Inn has increased significantly.

 

Which of the following, if true, most helps to explain the increase?

 

A.   Unlike the Wildflower Inn, Martin’s Cafe serves considerably more meals on weekends than it does on weekdays.

B.    Most of the customers of Martin’s Cafe had never dined in Riverville before this restaurant opened, and on most days Martin’s Cafe attracts more customers than it can seat.

C.   The profit per meal is higher, on average, for meals served at Martin’s Cafe than for those served at the Wildflower Inn.

D.   The Wildflower Inn is not open on Sundays, and therefore Riverville residents who choose to dine out on that day must either eat at Martin’s Cafe or go to neighboring towns to eat.

E.    A significant proportion of the staff at Martin’s Cafe are people who formerly worked at the Wildflower Inn and were hired away by the owner of Martin’s Cafe.

Q32:

Which of the following most logically completes the argument?

 

Although the pesticide TDX has been widely used by fruit growers since the early 1960’s, a regulation in force since 1960 has prohibited sale of fruit on which any TDX residue can be detected.  That regulation is about to be replaced by one that allows sale of fruit on which trace amounts of TDX residue are detected.  In fact, however, the change will not allow more TDX on fruit than was allowed in the 1960’s, because ______.

 

A.   pre-1970 techniques for detecting TDX residue could detect it only when it was present on fruit in more than the trace amounts allowed by the new regulations

B.    many more people today than in the 1960’s habitually purchase and eat fruit without making an effort to clean residues off the fruit

C.   people today do not individually consume any more pieces of fruit, on average, than did the people in the 1960’s

D.   at least a small fraction of the fruit sold each year since the early 1960’s has had on it greater levels of TDX than the regulation allows

E.    the presence of TDX on fruit in greater than trace amounts has not been shown to cause any harm even to children who eat large amounts of fruit
