Sufficient and Necessary Question Set #4

[cmorris32]

Hello!

I have a question regarding problem #4 on the Sufficient and Necessary Question Problem Set in Chapter 6 of the Logical Reasoning Bible (p. 246). I understood from the question that the chain of statements was:
inspired musical performances --> good show --> sophisticated listeners --> understand musical roots

How do I develop a contrapositive of this chain of statements? Would it be:
understand musical roots (NOT) --> sophisticated listeners (NOT) --> good show (NOT) --> inspired musical performances (NOT) ?

Thank you!

Hi C,

Yes, that is exactly right—well done! You take two basic steps to to create a contrapositive:

1. You reverse all the terms.
2. Then you negate all the terms (sometimes harder than it looks, but easy here).

You did both of those, and so you are right on the money. Good job!
