So if I answered A before you displayed the rest of the question, would that section contain what would be considered a conclusion?

*_If more than three inches of snow accumulate, then classes will be canceled.

3+IS > CC

3+IS ←s→ -CC

If more than three inches of snow accumulate, then some classes will not be canceled_*

Would this also be correct?

Dolphins are "water-breathing mammals", I would say. It depends on how you define "breathe".

How do we know if an answer choice is the best without reading through all the answers? I recognized immediately that A was a great choice, but nonetheless felt compelled to read through the rest of the answers to be safe.

I am also thrown a bit on how to distinguish between which answer "best" supports or refutes an argument, with multiple competing choices.

How can we distinguish between competing answer choices to determine which one MOST strengthens the argument?

That is such an ambiguous last sentence. What does it even mean?

Feeling kind of annoyed that I was sent to the old LSAT schedule and not the new one from the start. I just wasted a day and a half on the old schedule, and it's unclear what I need to do, and what I need to skip on the old one.
