Scientists believe it is possible that the universe is _ , but if it isn't, it would have to then have defined boundaries.
A. informative
B. cognitive
C. infinite
D. numerous
题目解答
答案
C. infinite
解析
本题考查形容词辨析,核心在于理解题干中逻辑关系。关键点在于“if it isn't, it would have to then have defined boundaries”,即“如果不是某种状态,就必须存在边界”。因此需要选择一个与“无边界”相关的形容词,其反面即为“有边界”。
-
选项分析:
- A. informative(信息丰富的):与“边界”无关。
- B. cognitive(认知的):与“边界”无关。
- C. infinite(无限的):表示“无边界”,其反面“有限”对应“有边界”,符合逻辑。
- D. numerous(大量的):描述数量,与“边界”无关。
-
逻辑匹配:
题干中“if it isn't”对应“如果宇宙不是无限的”,则必然存在边界。infinite(无限的)与“有边界”构成直接反义关系,是唯一合理选项。
