I chose the argument

“I’m on my way to school. I left five minutes late. Traffic is heavy. Therefore, I’ll be late to class. So I might as well stop and get breakfast.”

Yes it is an argument.

1. I’m on my way to school

2. I left five minutes late.

3. Traffic is heavy

4. I will be late to class.

Conclusion: I might as well get breakfast

Additional premises needed: Since I left late and traffic is heavy I will be late for class

Identify the sub argument: The sub argument is statements 1 and 4 because they contribute to the conclusion.

Good Argument: No it is not a good argument because you are late to class and this is the arguments concern and therefore you stopping for breakfast will make you more late which is what you are trying to avoid in the first place.

I think this exercise was useful because it made us break apart the argument and analyze it. It makes you think about how the different parts of the argument relate to the conclusion.
