The psychologist told him to ................. on the part of the problem that troubled him.
پاسخ صحیح: گزینهٔ A — focus
پاسخ تشریحی
The blank is followed by the preposition on, and the sentence needs a verb meaning to concentrate attention on something. "focus on the part of the problem" is the standard collocation — to direct one's attention to a particular thing. "solve" takes a direct object (solve the problem, not "solve on"), "blame" is illogical here, and "base ... on" would mean to found/ground something on, which does not fit "told him to base on the part of the problem." So focus is correct.
