conditional: if both A + B, then C
contrapositive: if NOT C, then NOT A +/or B

question: Why the heck does this contrapositive contain “or”!?

Thanks

It is much more likely that you will diagram a MBT question as opposed to a ~MBT question. So you do want to ask yourself that question after both types, but there is about a 50% chance on a MBT and only about a 10% chance on a ~MBT.

As you work through the course, you will find that certain question types are much more likely to be diagrammed. It is important to keep a mental note of these.

Good luck-

That’s precisely right. In fact, even as you’re reading the stimulus, you should be asking whether these seem like the sort of conditional claims that would tend to justify a formal deduction.

In many Soft Must Be True questions, the stimulus is simply describing a situation you’re supposed to evaluate and these (as you suggest) are not helpful to diagram.

Anticipating which type of question you’re dealing with is crucial in determining an approach to take.

After reading the question prompt for a Must Be True or a Soft Must Be True, should you be asking yourself after reading the stimulus was this conditional or situational?

Thanks !!

P.S. I’m taking your on-line course and just watch you go over converse and inverse problems
