刚刚翻了一下难题库给的答案,答案上面说,原文说的是galaxy里面找不到这样的世界,A选项说的是整个宇宙里面有大量的行星,两个的范围不对等。
解释具体如下:
This may look like it weakens the justification. After all, if the total number of planets were significantly smaller than millions, then the sample size of over 200 planets would allow us to make the inference with more confidence. Nevertheless, particularly when accounting for the vagueness of the conclusion, the size of the sample is large enough to give us a reasonable degree of certainty. More importantly, though, note that the conclusion is restricted to planets orbiting stars in our galaxy. There is nothing in this answer choice to suggest that the planets it refers to are actually in our galaxy. |
