Yes, it is clear that 3 and 5 are complex arguments but the answers don't reflect that. I wish the answers included differentiation between all the sub-premises and whatnot, as the lesson had described. #feedback

All of the sentences in drill 2 are just statements. Sure, they are likely true statements and have a relationship with each other, but there is no aim of persuasion present in the text. There is no argument.

I believe this is meant to mimic the often convoluted and difficult to understand language of the LSAT. In a world where you have no outside knowledge and lived experience, the grammar of the statement doesn't make that much of a difference to whether or not this is an argument with premises and a conclusion.

Does Mr. Fat Cat even like salmon? My cat doesn't! ;)

You could even push this further to clarify the assumption that rainy weather leads to a weakened immune system and sickness:

"I am going outside where it is raining. Rainy weather can weaken my immune system, exposing me to illness. Wearing a jacket in the rain will protect my immune system from getting sick. I don’t want to get sick so I am going to wear a jacket."

Hmm...Fat Cat/Trash argument was the weakest! I think maybe Fat Cat/Trash argument becomes the defacto weakest because Tiger argument, although vague, is more true than assuming that Mr. Fat Cat is the culprit, which relies largely on hypothetical evidence.

Commenting before answer reveal:

I believe that the Disney Vacation Club argument is strongest because it is tied to contractual obligations and limits associated with being a Vacation Club member. These terms are binding, making the argument that Walt sacrificed the required amount of goats more compelling.

The Tiger argument is the weakest because it is too vague. Yes, the premise and conclusion support each other, but counter-evidence could be demonstrated to weaken the argument very easily.

The Fat Cat argument is the middle ground in terms of strength.
