When faced with a Roman numeral-style question, use the structure of the question to your advantage. Look over each statement (I, II, and III). Consider each carefully and try to eliminate any that are inconsistent with the truth or falsehood of the stimulus.
If you can disprove one of the Roman numeral statements, you can quickly eliminate any answer choice that includes that particular statement, saving you time and increasing your chances for a correct answer if you have to guess between the remaining answer choices.
