I'm not quite sure about why C is the correct answer. It seems that we have to refer to the beginning of the second paragragh to answer this question.
Is this answer correct because the writers of literature use the law loosely to convey a particular idea, so the legal training might be useful/helpful to deal with literature which involves the answer to a legal question?
Furthermore, I'm also quite confused that why Posner uses line 22-25 as reasons to criticize the assumption that lawyers can offer special insights into literature that deals with legal matters ?
Could anyone explain it ?
Thanks.
