Colin's Answers

I am looking at a quiz taken by Colin.  He got an F.  The quiz was to see how well they had listened to a presenter who came to talk about drug use and stranger danger.  I don't know what the questions were.  I only have his answers.  Even without the questions, I can see why he got an F.
This is what it says:

1) Police
2) Football Player
3) Engineer?  I'm just guessing.
4) I don't know
5) Education is most important.

Only answer number 1 is a correct answer.
