*Please help me! I was given this 75 question packet earlier this week and all throughout the past few days I have been looking for the answers. This is a major part of my grade and its counted as a test grade, and if I fail this it will bring my grade down by a lot. These are the questions I can't find and if someone could help me get just one or two, that would greatly help me.*
