Music critic: Fewer and fewer musicians are studying classical music, decreasing the likelihood that those with real aptitude for such music will be performing it. Audiences who hear these performances will not appreciate classical music’s greatness and will thus decamp to other genres. So to maintain classical music’s current meager popularity, we must encourage more young musicians to enter the field.
Which of the following, if true, most weakens the music critic’s reasoning?
Musicians who choose to study classical music do so because they believe they have an aptitude for the music.
Classical music’s current meager popularity is attributable to the profusion of other genres of music available to listeners.
Most people who appreciate classical music come to do so through old recordings rather than live performances.
It is possible to enjoy the music in a particular genre even when it is performed by musicians who are not ideally suited for that genre.
The continued popularity of a given genre of music depends in part on the audiences being able to understand why that genre attained its original popularity.
错选D，个人分析，供参考。
研究OG的解释，这里应该是有pre-conclusion及mainconclusion 两部分推理线。
前提：学习古典乐的人减少，有资质演奏的人减少。（个人认为逗号前后的关系是题目给出的确定关系，不能作为攻击的地方）
Pre结论：观众听到这种演奏可能无法欣赏到古典乐的优美，从而专项其他类型的音乐。（will not，will都是推论的词语）
main结论：鼓励更多的人进入这种领域，保持古典乐目前不高的人气。（must）
所以可以削弱的关系有两处，前提到pre结论的关系，以及pre结论到main结论
1）有资质演奏的人减少，观众就一定无法欣赏了吗？（选项D）
2）观众无法欣赏现场演奏，通过鼓励年轻人进入这个领域就能保持古典乐的人气吗？（选项C）
而选项D的错误在于，it is possible这部分。存在一些人能欣赏，那么还有一部分不能欣赏的人，通过鼓励年轻人学习古典乐还是可以保持流行。
