Hint
This question uses what is referred to as the Roman numeral answer format. This format is used in both math and reading passage questions. The way to approach these is to work on each Roman numeral as a separate true/false question. Once you have decided (and marked) each Roman numeral as true or false, it’s easy to find the correct answer.

To test Roman numeral I, try out – as a value for x. Testing Roman numerals II and III means trying out 0 as a value of x and then as a value of x.
