参考答案:A解析: 根据题意,绳子长度比桥高的2倍还多8×2=16m。 绳子的长度比桥高的3倍还多2×3=6m。 所以桥的高度为16-6=10m,绳子的长度为2×10+16=36m。

Questions 10—11 are based on the following:
Antinuclear activist: The closing of the nuclear power plant is a victory for the antinuclear cause. It also represents a belated acknowledgment by the power industry that they cannot operate such plants safely.
Nuclear power plant manager: It represents no such thing. The availability of cheap power from nonnuclear sources, together with the cost of mandated safety inspections and safety repairs, made continued operation uneconomic. Thus it was not safety considerations but economic considerations that dictated the plant’s closing.

The reasoning in the manger’s argument is flawed because the argument

A.fails to acknowledge that the power industry might now believe nuclear power plants to be unsafe even though this plant was not closed for safety reasons

B.overlooks the possibility that the sources from which cheap power is available might themselves be subject to safety concerns

C.mistakes the issue of what the closure of the plant represents to the public for the issue of what the managers’ reasons for the closure were

D.takes as one of its premises a view about the power industry’s attitude toward nuclear safety that contradicts the activist’s view

E.(E) counts as purely economic considerations some expenses that arise as a result of the need to take safety precautions
