Answer:
Big business demands superior forecasting, reporting, and analyzing.
Explanation:
Parallel structure (parallelism) is the repetition of a chosen grammatical form within a sentence. This structure is used to add clarity to the writing and to make it easier to understand.
<u>From the given sentences, only the sentence - </u><u>Big business demands superior forecasting, reporting, and analyzing</u><u> - has a parallel structure. It creates a parallel structure with words that end in -ing: forecasting, reporting, and analyzing.</u>
Other sentences don't have parallel structures:
