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 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

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

  2. 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.

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

  4. Numerous counterexamples were necessary in order to show the Ptolemaic theory to be false

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

"The argument above is open to the objection that it makes the questionable assumption that " 是啥意思? 答案是E.

这道题说:一个理论要么对,要么错

伽利略证明了p的理论是错的,而因为C的理论和p的理论不一致,所以伽利略证明C的理论是对的

假设就是:p和c不一致的,不都是错的

The argument above is open to the objection that it makes the questionable assumption that (上面的argument是遭到反对的,因为它做出了什么有问题的假设)
