Question

Why is verisimilitude important?

Answer 1

The reader must be drawn into a fiction's reality for the story to make any impact. A work of art should convince the audience by imitating and representing nature and having basis in reality.

Explanation:

A completely unbelievable story, or one in which the believability is
jarred by inconsistencies is not enjoyable to the reader.

In a literary work, verisimilitude is likeness to the truth i.e. resemblance of a fictitious work to a real event even if it is a far-fetched one. A work of art should convince the audience by imitating and representing nature and having basis in reality.
