1. GWD-25-Q30//////////////////////////////////////

Museums that house Renaissance oil paintings typically store them in environments that are carefully kept within narrow margins of temperature and humidity to inhibit any deterioration. Laboratory tests have shown that the kind of oil paint used in these paintings actually adjusts to climatic changes quite well. If, as some museum directors believe, paint is the most sensitive substance in these works, then by relaxing the standards for temperature and humidity control, museums can reduce energy costs without risking damage to these paintings. Museums would be rash to relax those standards, however, since results of preliminary tests indicate that gesso, a compound routinely used by Renaissance artists to help paint adhere to the canvas, is unable to

withstand significant variations in humidity.

In the argument above, the two portions in boldface play which of the following roles?

A. The first is an objection that has been raised against the position taken by the argument; the second is the position taken by the argument.

B. The first is the position taken by the argument; the second is the position that the

argument calls into question.

C. The first is a judgment that has been offered in support of the position that the argument calls into question; the second is a circumstance on which that judgment is, in part based.

D. The first is a judgment that has been offered in support of the position that the argument calls into question; the second is that position.

E. The first is a claim that the argument calls into question; the second is the position

taken by the argument.

答案为什么是 D啊第二个怎么是the second is that position.

1. GWD-17-Q30////////////////////////////

In a study conducted in Pennsylvania, servers in various restaurants wrote “Thank you” on randomly selected bills before presenting the bills to their customers. Tips on these bills were an average of three percentage points higher than tips on bills without the message. Therefore, if servers in Pennsylvania regularly wrote “Thank you” on restaurant bills, their average income from tips would be significantly higher than it otherwise would have been.

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

The “Thank you” messages would have the same impact on regular patrons of a restaurant as they would on occasional patrons of the same restaurant.
Regularly seeing “Thank you” written on their bills would not lead restaurant patrons to revert to their earlier tipping habits.
The written “Thank you” reminds restaurant patrons that tips constitute a significant part of the income of many food servers.
The rate at which people tip food servers in Pennsylvania does not vary with how expensive a restaurant is.
Virtually all patrons of the Pennsylvania restaurants in the study who were given a bill with “Thank you” written on it left a larger tip than they otherwise would have.

答案是B 但为什么E不对
