Your taking a test. First directions say to read all the questions before you begin. You decide that is a waste of time and go ahead and start answering the questions. You get to the last question, and that question reads this “If you followed directions then only answer questions numbered 3 and 5 only.” Well you just answered 18 questions (if it was a 20 question test) for no reason. And failed the test if it is a test on following directions. Now had you read all the questions as directed you would of have known to answer only numbers 3 and 5….and passed..

Point made I hope.

makes it clear

doesn’t confuse you
