Sorry I only have answers starting at unit 9 but will be putting up earlier units asap. If you know some of the other answers, you can email me at 13nman@gmail.com for permission to edit. I will be updating this as frequently as possible but it is a painstaking process that could take a while. I am in no way related to Sadlier-Oxford or Jerome Shostak and am just a high school student trying to help others out. I do not guarantee that these answers are correct and therefore hold no blame if you get a bad grade. However, if you find an error in my answers, feel free to send me an email and I will fix it.
