Writers should use juxtaposition to build narrative tension within chapters.

Evidence

You can see, I hope, the implication for writing narrative nonfiction: one way to think about chapters is to think about them as the narrative blocks in a panel and to think about the gap between panels as a chapter break. … However, you can also think about building narrative or character within a chapter using this technique of juxtaposition. Essentially, you offer one moment of, say, character, perhaps using a fish-eye technique to create subjective intensity. You write a gap, and then you follow up with the (unspoken but implied) narrative consequence. — Tilar J Mazzeo, How to Write a Bestseller, 532
