I was wondering if someone could help me with problems on my
test my teacher allows me to correct the wrong ones then give them
back for half credit. Along with the correct answer for each I’d
like to know why the answer I chose is wrong what is the correct
answer and why it is the correct answer. The marked red problems
are the incorrect problems.
