10. Consider the following argument. Without building a truth table, decide whether or not you think it is valid. Write down your answer, and explain in your own words why you think the argument is valid or invalid. Remember, do not build a truth table! This problem is just to get you thinking. You will not be graded on whether you are correct, but you may lose points if you don't really try to come up with an answer and an explanation, or if we can't understand what you're talking about.
