Parallel structure means items in a series share the same grammatical form. Option B presents three parallel noun phrases: “campus safety,” “advisor meetings,” and “course registration.” Each item is a concise noun-based unit, creating balanced rhythm and clarity. Option A mixes a noun phrase (“campus safety”), a gerund phrase that begins with a participle (“meeting advisors”), and an infinitive-like “how to register,” producing uneven structure. Option C combines a prepositional phrase (“safety on campus”), an infinitive with “to meet,” and a gerund “registering”—again nonparallel. Option D starts with an infinitive clause (“to be safe on campus”) and then shifts to mixed forms. On the PERT, quickly test parallelism by placing the verb in front of each item: “covered campus safety,” “covered advisor meetings,” “covered course registration.” The symmetry in B reads naturally. Parallelism isn’t just a stylistic nicety; it aids comprehension by signaling equivalence among items, which is essential in academic lists (methods, outcomes, requirements) and reduces processing load on readers.
