问题 Which of the following is the best title for the passage?
What can be inferred from the passage?
选项 A、The climate of earth has fluctuated quite a bit over the last 4.6 billion years.
B、An increase in the earth’s temperature will have major consequences for all life on this planet.
C、The information we have got makes us unable to explain the global warming completely.
D、The Pleistocene began about 1.8 million years ago.
答案C
解析 推断题。文章第六段第二句指出，我们(人类)在地球上的短暂历史和对气候更加简短的记载，不足以让我们完全了解地球升温的含义，由此可以推断，C正确。A、B、D项都是原文所述事实，不是推论所得，不符合题目要求。
