Question

1. which of the following best describes a main event in a story? an explicit expression of the author’s philosophical leanings dialogue between characters irrelevant or tangential background information an occurrence that contributes to developing the primary theme

Explanation:

A main event in a story is an occurrence that helps develop the primary theme. It is not about the author's philosophical leanings (which are more about the author's worldview outside of the story - events themselves), not just dialogue between characters (which can be part of a main - event but not the best description of a main event), and not irrelevant or tangential background information.

Answer:

an occurrence that contributes to developing the primary theme
