Question 9.

Option C is the correct answer. 

The first paragraph describes how Becker projected economics into non-market domains like crime and domesticity, analyzing them with economic tools. It also states that he did not borrow ideas or perspectives from fields such as anthropology or history. Option C aligns with this.

Option A: The passage mentions that Becker applied economic principles to non-market phenomena like crime and domesticity, but it does not state or imply that he benefitted from this.

Option B: The passage explicitly contradicts this idea, stating: “At the same time, he did not let other ways of thinking enter his own economic realm: for example, he did not borrow from anthropology or history.” Becker did not borrow from other disciplines, so this option is incorrect.

Option D: The passage does not state that Becker actively guarded economics against outside influence. Instead, it focuses on Becker’s one-sided application of economics to other areas, without accepting external perspectives.
