Answer:
D) Use key details to find the main idea
Step-by-step explanation:
Using important information in a text like for example: Events, problem, solution, or the setting of the story, can help you find the main idea of a story. Also things like who, what, where in an event. A - Using context clues to find the main idea would be wrong because that is what you should do if you don't know what a word means. B is also wrong because a glossary tells you what a certain word means like an dictionary. C is obviously wrong because looking for the theme of an story is the meaning of a story not the main idea. So your only option left would be D
