how many central ideas can a text have? more than one only one none

Answer:

B. only one

Brief Explanations:

A text typically has one central idea. This idea serves as the core or main theme that the text revolves around. While a text may have multiple supporting ideas or sub - themes, there is usually a single overarching central idea that ties everything together. For example, in an essay about the benefits of exercise, the central idea is the positive impact of exercise on health, and supporting ideas could be improved cardiovascular function, better mental health, etc. If there were more than one central idea, the text would likely lack focus and coherence. And a text cannot have no central idea as it would be a collection of random thoughts without a purpose or direction.
