correct answers

There are no answer keys. If you're a student, you have to do the worksheets and then check which are correct and which are not. If you're a teacher, it's good practice to do the worksheet as if you were a student before assigning it, to find out if it's suitable and the answers are correct. We make no comments about answers. There are way too many students looking for shortcuts. I hope you understand. To the REST OF THE COMMUNITY, please don't post any answers here.
