问题 According to the passage, the chief purpose of explorers in going to unknown places in the past was______. [br] The passage tells us that proof of life on Mars would______.

选项 A、make clear the complex chemistry in the development of life
B、confirm the suggestion that bacterial fossils traveled to Earth on a meteorite
C、reveal the kind of conditions under which life originates
D、provide an explanation why life is common in the universe

答案 C

解析 细节题。最后一段倒数第二句话说:对火星上过去或现在是否存在生命给出一个更确凿的、令人信服的回答,会给研究者提供产生生命条件的宝贵数据。这与C项的表述一致。而只有进一步证明生命在火星上不仅仅存在而且是独立产生的,才能进一步解释“生命在宇宙中是否普遍存在”这个谜,所以不能选D项。
