How to answer “I, II and III” questions
- Judge each statement on its own. Write ✓ or ✗ next to it before you look at the options.
- Start with the statement you are surest about, then cross out every option that disagrees with it. Often one sure statement leaves only two options.
- Watch for words such as always, only, never or zero: one counter-example makes the whole statement false.
- Do not choose “I, II and III” just because all three sound familiar. Every statement must be true in this exact situation.
