to bear or hold up; serve as a foundation for
the topic of the text - usually one or two words at most
a term that means the same thing as main idea
the reader has to figure out the main idea of a text

Explanation:

To determine the central idea's definition, we analyze each option:

• The purple - red option defines a "topic" (short, 1 - 2 words), not central idea.
• The dark purple option defines a verb related to "support", not central idea.
• The blue option describes the reader's task of finding the main idea, not the definition of central idea.
• The green option states it's a term synonymous with "main idea", which matches the concept of central idea.
