I need to know how to write an opinionated question?

Answer 1

Classic opinionated questions make an assumption in the question.

Examples:

When did you stop beating your wife? (assumes he has been beating her)

Why did you skip school so often? (assumes the student wasn't excused)

Or -- are you asking about opinion questions?

Examples:
Why do you want McCain to be president?
Should we abolish the death penalty?

Answer 2

The assignment is to make the question opinionated as well as make it argumentative for class discussion.

One topic is the treatment of prisoners during war time. Can you give me an example of that?

Answer 3

How does torturing prisoners keep America safer?
