Life, as we know it, most likely would exist on Mars near its ______.
"Speculation is science’s very life-blood" means that scientists ______.
选项
A、are gamblers on science
B、must form opinions about the data they gather
C、must concern themselves with provable facts
D、must understand all sciences
答案
B
解析
“speculation”在本文中的意思是“推测”,并非“投机”,所以科学家们不是科学方面的赌徒。原文第二段说明,仅仅积累事实只是科学的原始形式,我们还必须从这些事实中总结出自己的观点。
