Correct answer: C
Concept: When two or more actions are joined by a coordinating word such as “and” or “or” and share the same governing verb or phrase, all of the joined actions must take the same grammatical form — this is the rule of parallel structure. If one action is expressed as a simple infinitive (“to” + base verb), every other action tied to it by “and”/“or” must also be a simple infinitive, not a different tense, aspect, or verb form.
Application: The full sentence reads: “The method suggested in the lecture enables a student to learn more quickly and to have remembered for a longer period of time.” Both “to learn” and “to have remembered” are joined by “and” and depend on the same verb “enables.” Since “to learn” is a simple infinitive, the second action must also be a simple infinitive — “to remember” — not the perfect infinitive “to have remembered.” The phrase “and to have remembered for a longer period of time” therefore breaks the parallel structure and is the grammatical error in the sentence.
Cross-check: Rewriting the phrase as “and to remember for a longer period of time” restores the parallel form (“to learn … and to remember …”), and the sentence otherwise reads correctly: the subject phrase, the verb agreement, and the overall sense show no further fault.
