Answer:
OA. Exploring a history museum inspired my dream of a career as an archaeologist.
Step-by-step explanation:
The controlling idea of a paragraph is the main topic or reason of the paragraph. This means that the controlling idea is the main idea or the direction the passage will take.
In the given passage, the speaker tells us about how he/she came to be an archaeologist. Talking about how teens aren't normally attracted to museums, the speaker then moves on to tell us about the experience that changed or became the deciding point for his/her life. So, the controlling idea of the whole passage seems to be that the narrator's visit to the history museum inspired him/ her to become an archaeologist.
Thus, the correct answer is option A.
