回複：第2題...請邏輯好的高手給解釋一下.

Argument #: there are living communities of microorganisms there that have been cut off from surface life for millions of years.

Supporting Fact#: the discovery of living microorganisms in samples of material that were taken from holes drilled as deep as 1.74 miles.

One may argue that the samples used for supporting the claims by scientists may be from different depths or surface soil during the drilling process, which weakens the claim.

Thus, you need C as an assumption.

option E is irrelavent to the claim.

• 即使答案D是正確的,也隻不過是已陳述事實的補充,而不是另一個假設條件. -ntotl- ♂ (0 bytes) () 01/01/2010 postreply 20:17:15
