Name a key characteristic of effective expository writing.

A key characteristic of effective expository writing is clarity and conciseness. This style of writing is intended to inform or explain a topic to the reader in a straightforward manner. It prioritizes delivering information effectively, ensuring that the reader can easily understand the main ideas without unnecessary complexity or ambiguity.

Clarity involves presenting ideas clearly so that the reader can grasp the concepts quickly. Conciseness complements clarity by eliminating extraneous information that might confuse the reader or detract from the core message. As effective expository writing focuses on conveying ideas and information rather than embellishing them with complicated language or emotional appeals, clarity and conciseness become paramount for the success of the writing.

This is why options such as complex language and jargon, emotional appeal, and lengthy descriptions do not align with the primary goal of expository writing, which is to educate or inform efficiently.
