Whenever possible try to repurpose a term from the sentence as a prediction for the term in the blank before looking at the choices.
In this case it is known that people are "often extremely critical of the medical profession", but rarely willing to do the same to their personal doctors, so simply predict a phrase such as "extreme criticism" for the blank.
Now, look to the choices for a term that matches "extreme criticism" in context.
(A) impetuosity - does not match "extreme criticism" - eliminate Choice A
(B) sarcasm - does not match "extreme criticism" - eliminate Choice B
(C) mockery - does not match "extreme criticism" - eliminate Choice C
(D) contempt - does broadly match "extreme criticism" - keep choice D
(E) condescension - does not match "extreme criticism" - eliminate Choice E
Read contempt in the sentence to confirm that it imparts the intended meaning, before selecting Choice D.
