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.

答案給的是E

One week, the station received 50letters with favorable comments about the stationâ?s news reportingand music selection and 10 letters with unfavorable comments on thestationâ?s new movie review segment of the evening program. Faced withthis information, the programming director assumed that if somelisteners did not like the movie review segment, then there must beother listeners who did like it. Therefore, he decided to continue themovie review segment of the evening program.

对不起好几天没上网。原题不是这道题，是music，不是letter。

以前radio station在节目之间放7首歌。现在要加放3首，所以原来的广告时间会减短，广告收益会变少，问假设。

答案是：原有的7首歌的length不会减短。

激发记忆想起~wow~

vote for B
根据这句话“the programming director assumed that if somelisteners did not like the movie review segment, then there must beother listeners who did like it”
B说的是“他不能正确的从已知信息--某些听众不喜欢movie review segment就推出另外有某些人会喜欢”
