问题 Which of the following questions does the passage supply information for answering?
The passage suggests that if there were a slight global warming at the present time, it would be______.
选项 A、difficult to measure the increase of carbon dioxide in the atmosphere because of local variations in amounts
B、easy to demonstrate the effects of the warming on the water vapor in the atmosphere
C、difficult to prove that the warming was mused by the burning of fossil fuels
D、easy to prove that the warming was caused by an increase of cloud cover
答案C
解析 推断题。题意为："文中暗示如果目前全球稍微变暖，那么______"。根据第四段第二句 (但是假设实际上全球气温上涨1℃，可能仅仅意味着几个有许多气象站的地区因气流循环模式的变化导致的气温的升高)，可知"很难证明气候变暖是燃烧化石燃料造成的"为正确答案。
