问题 Future space exploration will______. [br] If the land area of the earth is about 55,000,000 square miles, the area that can be explored in space is probably______.
选项 A、55,000,000 square miles
B、70,000,000 square miles
C、13,720,000 square miles
D、550,000,000 square miles
答案 D
解析 本题题干问“如果地球所能探索的面积是55,000,000平方英里，那宇宙可探索的面积是多少”。原文第1段第5句话指出宇宙将留给我们像地球大陆十倍的地域去探索。因此选项D．550,000,000 square miles是正确答案。
