Question

what is a good central idea for this speech?
how does reading labels improve diet and health decisions?
experts are the only people who can adequately read food labels.
reading nutrition labels improves diet and health with informed choices.
topic: nutrition labels
general purpose: to inform
specific purpose: to inform the audience about how reading nutrition labels promotes healthy choices
central idea: ?

Explanation:

The central idea should directly state the main point. The first option is a question, not a statement. The second option is too narrow (only experts) and not in line with the purpose (to inform about how reading labels helps everyone). The third option aligns with the topic (nutrition labels), general purpose (to inform), and specific purpose (how it promotes healthy choices) as it is a clear statement of the benefit of reading nutrition labels.

Answer:

Reading nutrition labels improves diet and health with informed choices.
