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 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.

                     我觉得因该选A，答案怎么是C？A说可以追踪电话从哪里打的，所以可以减少匿名的恶作剧的火警电话，肯定应该是A啊，c和恶作剧无关啊

Q11:

Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species.  Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates.  Clearly, dropping this restriction would allow the other species to recover.

Which of the following, if true, most seriously undermines the argument?

1. Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
2. It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
3. The number of snow geese taken by hunters each year has grown every year for several years.
4. As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
5. In the snow goose’s winter habitats, the goose faces no significant natural predation.

   Answer: 到底是哪个啊？
