第8题:

If the ratio of brown cars to blue cars in a certain parking lot is 2:3, how many brown cars are in the lot?

(1) There are 15 blue cars in the lot.

(2) There are 25 cars total in the lot.


正确答案:D
D 解析:When we evaluate statement (1), we can tell that there are 10 brown cars in the lot, because that's the only number that would give us a ratio of 2:3 if there are 15 blue cars. So we can eliminate B, C, and E.
Taking statement (2) alone, we can tell that we have 15 blue and 10 brown cars in the lot, because those are the only numbers that would add up to 25 and give a ratio of 2:3. So either statement is sufficient on its own, which means D is the correct answer.

第9题:

Motor vehicles powered by the internal combustion engines are responsible for over 80 percent of the deadly carbon monoxide as well as the cancer-causing substances in the air. Eighty-nine percent of the vehicles on the road in Massachusetts are privately owned and are often operated with only one person in the car. If people would use public transportation instead of their cars, air pollution levels could be significantly lowered. Thirty percent of the land in downtown Boston is devoted to cars. Where there are garages, there could be gardens. Where there are highways, there should be homes and places to work and play. Studies show that people today show a greater hearing loss with age than ever before. Much of this is due to car-horns, loud engines and general traffic noise.

The cost of a personal car is high to the individual. The average person pays about $2,000 per car per year in gasoline, insurance, taxes, and maintenance. But for society as a whole, personal cars are a luxury we cannot afford. We pay in death from auto accidents, in poor health from air pollution, in loss of hearing from noise pollution, and in the destruction of our cities by the ever-increasing number of highways.
