标题: [求助]急问gwd31-9-32

Q32:

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

The argument above is open to the objection that it makes the questionable assumption that

A. whoever first observed something inconsistent with the truth of the Ptolemaic theory should be credited with having proved that theory false

B. there are some possible observations that would be inconsistent with the account given by the Copernican theory but consistent 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 in order to show the Ptolemaic theory to be false

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

答案是E，哪位好心人可以给我解释一下吗？谢谢！

奋勇下，

Ptolemaic theory 中讲的是　celestial bodies 而Copernican theory 中讲的是 the planetar；P theory 中　C bodies错，如果和C theory矛盾，是C theory的C bodies对，并未证明the planetar 对。是不是犯了偏盖全的错误。

题干:G的观察显示P理论是错的,而C理论和P理论不一样,那G的观察证明C理论正确

题目:上述论述因做了啥假设而易被反对

答案:C理论和P理论不一样,不可能同时都错；
