Answer:
Two sentences from the article that include central ideas are:
1. While each utopian community had differences, they shared a common vision of living together.
2. They survived by modifying their system into two distinct organizations, one secular and one religious.
Explanation:
A central idea is the main point or theme that the author is making in the writing or presentation. It is also called the main or key idea. This implies that the central idea is the focus of an article or a presentation. The sentence that contains the central idea is called a thesis statement. This captures the claim being presented in an article. However, a text or presentation could contain more than one central idea.
