标题: GWD 11 Q32

A theory is either true or false. Galileo’sobservations of Jupiter’s satellites showed that the Ptolemaic theory of themotion of celestial bodies is false. Therefore, since the Copernican theory ofplanetary motion is inconsistent with the Ptolemaic account, Galileo’s observationsof Jupiter’s satellites proved the truth of the Copernican theory.

The argument above is open to the objection that itmakes the questionable assumption that

A. Whoever first observed somethinginconsistent with the truth of the Ptolemaic theory should be credited withhaving proved that theory false.

B. There are some possible observations thatwould be inconsistent with the account given by the Copernican theory butconsistent with the account given by the Ptolemaic theory.

C. The Ptolemaic and Copernican theories,being inconsistent, cannot both be based on exactly the same evidence

D. Numerous counterexamples were necessary inorder to show the Ptolemaic theory to be false

E. The Ptolemaic and Copernican theories,being inconsistent, cannot both be false.

E是什么意思呢。。明明不是最后说伽利略说哥白尼的是正确的么= =为什么我就是看不明白呢

题目是说伽利略的观察发现P原理是错的。因此，因为C原理与P原理相矛盾，所以伽利略的观察证明了C原理是正确的。
这里明显有一个Gap，要是C原理和P原理都错呢？——E说的就是这个

可是C原理和P原理不是相矛盾么- -为什么会说两个都错呢。。

两个相互矛盾的理论真的必须有一个对么？
比如说，伽利略说：地球围着星星转
哥白尼说：星星围着地球转
他们相互矛盾但都不对呀~~
