题目：

Twelve years ago and again five years ago, there were extended periods when the Darfir Republic's currency, the pundra, was weak:  its value was unusually low relative to the world's most stable currencies.  Both times a weak pundra made Darfir's manufactured products a bargain on world markets, and Darfir's exports were up substantially.  Now some politicians are saying that, in order to cause another similarly sized increase in exports, the government should allow the pundra to become weak again.
 
Which of the following, if true, provides the government with the strongest grounds to doubt that the politicians' recommendation, if followed, will achieve its aim?

选项:

A、Several of the politicians now recommending that the pundra be allowed to become weak made that same recommendation before each of the last two periods of currency weakness.
B、After several decades of operating well below peak capacity, Darfir's manufacturing sector is now operating at near-peak levels.
C、The economy of a country experiencing a rise in exports will become healthier only if the country's currency is strong or the rise in exports is significant.
D、Those countries whose manufactured products compete with Darfir's on the world market all currently have stable currencies.
E、A sharp improvement in the efficiency of Darfir's manufacturing plants would make Darfir's products a bargain on world markets even without any weakening of the pundra relative to other currencies.

B

题目：

Springfield Fire Commissioner: the vast majority of false fire alarms are prank calls made anonymously from fire alarm boxes on street
corners. Since virtually everyone has access to a private telephone, these alarm boxes have outlived their usefulness. Therefore, we propose to remove the boxes. Removing the boxes will reduce the number of prank calls without hampering people's ability to report a fire.
 
Which of the following, if true, most strongly supports the claim that the proposal, if carried out, will have the announced effect?

选项:

A、The fire department traces all alarm calls made from private tele-phones and records where they came from.
B、Maintaining the fire alarm boxes costs Springfield approximately five million dollars annually.
C、A telephone call can provide the fire department with more informa-tion about the nature and size of a fire than can an alarm placed from an alarm box.
D、Responding to false alarms significantly reduces the fire depart-ment's capacity for responding to fires.
E、On any given day, a significant percentage of the public telephones in Springfield are out of service.

答案:

A

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
