Answer:
Coherence in a nonfiction writing means that it is related in truth and accuracy about people, events and places.
Step-by-step explanation:
Coherent nonfiction writing can be of two types:
Historical nonfiction and creative nonfiction.
There are diferences such as the methodology / technique used to present the narrative and the language (formal or informal tone).
However, both intend to educate and inform. This important objective makes it paramount that whatever is presented is accurate, truthful and coherent, i.e has a logical chronological flow to its narrative.
