3.2 GWD
Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream. However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur. These results provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria.
Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?
A: After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.
B: Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
C: Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.
D: The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine.
E: Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice.
选B
22. GWD25-Q22.
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?
A. The fire department traces all alarm calls made from private telephones 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 information 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 department’s capacity for responding to fires.
E. On any given day, a significant percentage of the public telephones in Springfield are out of service.
