Question

which of the following sentences does not contain faulty parallelism?
kelly enjoys exercising daily, cooking, and to travel.
to prepare for off - roading, kasey must find a location, load the equipment, and securing safety gear.
successful exercise revolves around increasing heart rate, burning calories, and varying muscle focus.
when composing music, nikki considers tempo, tone, and to communicate emotion to her audience.

Explanation:

Parallelism requires the same grammatical structure. In the first option, "composing music" (gerund phrase) is not parallel to "to communicate" (infinitive). In the third option, "find a location" (verb - noun) and "load the equipment" (verb - noun) are parallel, but "securing safety gear" (gerund - noun) breaks the parallelism. In the fourth option, "exercising daily" (gerund - adverb) and "cooking" (gerund) are not parallel to "to travel" (infinitive). The second option has all gerund phrases: "increasing heart rate", "burning calories", "varying muscle focus".

Answer:

The sentence "Successful exercise revolves around increasing heart rate, burning calories, and varying muscle focus" does not contain faulty parallelism.
