I did my little brother's science homework and he ended up getting detention because one of the teachers thought my answer was 'wrong'. How can this be right?
Wait, he got detention because he got an answer wrong? I am left with my jaw dropping to the floor, is this for real?
I think that they felt the answer was too good so they assumed he cheated.
You shouldn't have done that. It would have been better if you explained the problem to him and let him fix it in his own words.
I just can't stand the fact that my little brother has the same unintelligent genes as his mother. I wish he was smart enough to do his own homework.
Cheating no matter what is bad, detention is something he doesn't deserve as it was you who helped him cheat. This should be done the right way in the future to avoid such punishment for homework.
