The rest can be figured from simple deduction.

Far, far too many multiple-choice tests, even those not aimed at small children, fall into the trap of wanting to have several nearly-right answers to trap people. So there will be one right answer, and four more that differ from the right answer in one way only. So you can use that pattern to find the correct answer -- for a start, any two answers that differ in two respects are usually both wrong.

From the age of about seven, when I first worked this out, to the end of secondary school, I only encountered one test (the National Maths Contest) where this method didn't get me at least some free answers.
