Suppose in a classroom, the teacher asks a student to analyze an option in a multiple choice question. The student didn't hear it clearly and asks
Sorry, I didn't hear it clearly. Am I supposed to analyze the option B or D?
... Am I expected ...?
When the two are used in the affirmative sense, I'd say they are relatively synonymous.
How about this kind of situation, general questions?
Do they mean the same thing?
