In any "neither . . . nor" phrase, the two elements mentioned in the phrase must be the same kind of word, but they are not the same kind of word in the above sentence. "Professional sports" is a simple noun, while "acting" is a gerund, or a verb form that functions as a noun. "Neither playing professional sports nor acting in film," featuring two gerunds, features a correct parallel structure in the "neither . . . nor" phrase.

The two items in the "Neither . . . nor" phrase describe different things: a noun, "football," and a gerund phrase, "playing tag." Any such phrase needs to have the same kinds of items described in its parts. "Neither football nor tag were allowed at recess" is the only answer choice that features a correct parallel structure.

The list featured at the end of the sentence contains unlike items, with two nouns ("pay" and "benefits") and a participle verb ("searching"). Any such list needs to have three similar items in order to appropriately complete the phrase in which it is the object. The only answer choice with a correct parallel structure is "and mostly had to do with severance pay, unemployment benefits, and employment searches."

Any list like the one in the underlined portion of the sentence needs to feature three similar items, which the list in the sentence does not have. The three items need to have a parallel structure so that they can appropriately be linked together. The only answer choice that features a correct parallel structure is "students' passions for painting, acting, and playing a musical instrument."

The compound object of the sentence features two unlike elements, "with skills" and "have awareness." The phrase needs to feature a parallel structure with like elements that describe a similar process. The only answer choice with an appropriate parallel structure is "The coach always wanted athletes with skills and awareness on the field."

The list that ends this sentence contains three unlike items, two gerunds ("shading" and "coloring") and an infinitive ("to frame"). Any such list needs to feature a parallel structure, with all items being the same kind of word. The only answer choice that features a correct parallel structure is "but also excels at shading, coloring, and framing."

The list of requirements of the committe contains two infinitive phrases ("to read documents" and "to argue contentious points") and one gerund phrase ("making judgment calls"). Any such list needs every one of its items to be the same kind of item, so they can be properly grouped together. The only answer choice to feature a correct parallel structure is "who were required to read documents, to argue contentious points, and to make judgement calls."

The phrase at the end of the sentence has two very different constructions for its objects, one simple description involving an object that is a noun ("it had a faulty battery"), and the other a verbal phrase ("the brakes were not working"). In a dependent clause with two objects, both need to have the same structure. The only answer choice with a correct parallel structure is "after which it had a faulty battery and non-working brakes."

The list that finishes this sentence must feature three similar items, so they can be properly grouped together. The list is written with two simple nouns ("art classes" and "language lessons") and one gerund phrase ("participating in sports"), meaning they need to be changed to matching items. The only answer choice that features a correct parallel structure is "between art classes, language lessons, and sports."

The list that finishes this sentence features unlike word forms in its items: it includes two gerunds ("breathing" and "balancing") and one infinitive ("to focus"). Any such list needs to feature words in the same form so that they can be properly grouped together, so the infinitive is not grammatically correct in this sentence. The only answer choice with an appropriate parallel structure is "as she deemphasized running and emphasized breathing, balancing, and focusing."
