Answer 1

Answer: 2

Explanation: A central idea is the definitive and unifying theme or idea of a story or article. It encompasses all the aspects necessary to create a coherent main idea. The central idea is typically expressed as a universal truth or theme that is built and supported by the setting and characters in a story.

Thus, to find a central idea the most recommended process to follow is to identify the topic, the medium and supporting sentences as these are w key elements of a text or speech that aim at supporting the main point or central ideas and by understanding the parts of the speech or text you will get the general idea of it.
