A theory is either true or false, G's observations...showed that the P theory of ....is false. Therefor, since the C theroy isinconsistent with the P account, G's observations ...proved the truth of the C theory. (具体的一些解释省略了) The argument above is open to the objection that it makes the questionable assimption that A whoever first observed something inconsistent with the truth of the P theory should be credited with having peoved that theory false. B there are some possible observations that would be inconsistent with the account given by the C theory but consistent with the account given by the P theory. C the P and C theoris,being inconsistent, cannot both be based on exactly the same evidence D numerous counterexample were necessaty in order to show the P theory to be false. E the P and C theories, be inconsistent, cannot both be false. 请路过的NN能告知一些这题的思路,我有点晕了^^^^^ 正确答案是E |
