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，The argument above is open to the objection that it makes the questionable assumption that怎么理解呢？
还有，这个有相关的讨论吗？
谢谢。

问题的解释为：以上的论述是受到反对的，这个反对是由于论述基于可质疑的假设，这个假设是一下的哪一条呢？ objection后面的that是做它的同位语

问题问你以上argument存在一个怎么样错误的假设。
题目中P错，因为C和P不致，所以C对。假设就是：他们两个不可能都错----------E

谁能解释下A?

個人愚見是
A在說 第一個發現和sth.和P理論不合的人就是被認為已經證明了P理論錯了(的人)
那題目中並沒有提到加利略是第一個發現木星群的人
如果這題把first拿掉的話
那A可能還會比E有說服力
