Problem 1: Make an original argument that is valid but unsound. Use premises and conclusions whose falsity is evident to all, and not personal information or a matter of opinion. We've given you some examples of valid forms, and you're free to use these if you wish. If you can imagine other valid forms, you're encouraged to try one as well. Do not, however, use actual arguments from the book, lecture, or posted by another student.
Problem 2: Choose an argument written by another student, and rewrite it as a sound argument--preserve the form, but create premises and a conclusion that are obviously true.
