Answer:
D. Those that are simple and direct
Step-by-step explanation:
When authors want to speed up the pacing of their story, they tend to use sentences in the active voice rather than the passive voice (Active voices sentences are shorter), they do not burden the text with overly-specific details about what is happening, therefore, the use of adjectives and adverbs is limited, and they almost never quote since it would imply to make the pace slower. Thus, sentences that are simple and direct in a story are the best choice for such purpose because they help the reader to understand what is happening in the story without thinking it through much.
