Final answer:
The argument is valid because the conclusion logically follows from the given premises.
Step-by-step explanation:
The argument is valid. To determine the validity of the argument, we can examine the premises and conclusion. The first premise states that if you give me a cheeseburger today, I will pay you tomorrow. The second premise states that if you are a sensitive person, you will give me a cheeseburger today. The third premise states that you are not a sensitive person. From these premises, we can conclude that I will not pay you tomorrow. This conclusion logically follows from the premises, making this argument valid.
