问题 It can be inferred from the first paragraph that
As to global warming in the next century, climate scientists’ answer is

选项 A、ambivalent.
B、inexplicit.
C、negative.
D、affirmative.

答案B

解析 本题是推断题。根据题目顺序定位至第四段。末句指出:there’s no way of telling whether warnings of catastrophe are overblown or if things are even more dire than we thought.结合第三段首句的“If the public is more aware, though, experts are more confused.”可以推断科学家们对于下个世纪的气候变暖情况没有给出确定答案,故[B]为答案。
