Asking for help a CR question

Mereology is the formal theory of part-whole relations that regards any     whole as identical to the sum of its parts. One element of this theory is the belief that any two objects with the same parts must be identical. However, due to the limitations of our observational techniques, we can never determine with certainty whether two objects are composed of identical parts . For example, we are unable to identify differences that could     be present at the sub-automic level. Therefore, mereology is yet another philosophical theory that has been debunked by the limitations of modern socience.


The reasoning above is most vulnerable to criticism on which one of the following grounds?


A. That some characteristics of sub-automic objects cannot be identified does not imply that some characteristics of sub-automic objects can be identified.


B. That it is impossible to determine whether two objects are identical does not imply that it is impossible to determine whether those objects are identical for all practical purposes.


C.That it is impossible to ascertain whether two objects are identical does not imply that two objects cannot be identical.


D.That the qualities of sub-automic objects cannot be determined does nto imply that it is possible to determine some of the qualities of larger objects.


E.That it is impossible to determine with certainty the characteristics of any given sub-automic objects dose not imply that it is impossible to determine with certainty the characteristics of all sub-automic objects.

仔细看看E不对，注意到for example, 这并不是逻辑主线．C对．谢谢bryony, 高手

呵呵，版主过奖了。其实我也只是感觉这个对。这个Elen MM怎么不贴答案的呀？这好像不像GMAT的题，倒是很像LSAT的题型呀。


随便问一句，weiyu版主是要考LSAT还是GMAT？感觉你对LSAT钻研得很深呀。

Thanks a lot!


The question is from Kaplan LSAT test,    unfortunately ,    I don't have anwser.


I choose E, but read you guys'    analysis , I think C is correct one.


Want another shot? I have one more.
