Teacher put all of the answers to the homework in white font? We have Science homework due tomorrow and it's basically a "fill in the boxes" homework about energy in Microsoft Word. Well, my friends and I quickly realised that the teacher had put all of the answers in white font in the boxes. So, all we need to do is change the font to black and there's our homework.

I really don't know if this was an accident, intentional or a trap to test which of us are honest or not. So what do I do?

Do I just turn the font to black, read it over and laugh at how easy it was, or do I delete the boxes and actually try? I know which one I should do, of course, but if all the people in my class have done that and the answers are the same, what do I do?
There are several reasons you should do the work yourself, ignoring the filled in answers:


It is the honest thing to do.
You will learn far more from the homework that way.
The filled-in answers may not be the right answers. For example, the teacher could have used a file from someone who had done the homework for calibration, and made some mistakes.
If the teacher sees a lot of 100% correct answers, with exactly the same wording and formatting, they may become suspicious and realize what was going on. In that case, it may be very important to be able to honestly say you did the work yourself.
