Compund & Contradictory Claims

Two things that I enjoyed learning about from chapter 6 are "Compound Claims and "or" claims" and the "Contradictory of a claim". Through compound claims, the author suggests that these types of claims can be composed of different claims but is only viewed as one. An example of that would be:

Either I pass in this writing class or fail

This is an example of a compound claim because it combines two claims  "Either I pass in this writing class" and "Either I fail in this writing class" into one claim. 

In other words, a contradictory of a claim is generally the opposite of a claim, like above, an example would be:

Claim: I passed my writing class because I got an A on my final.
Contradictory claim:  I failed my writing class because I got a F on my final. 

The second is a contradictory claim because it claims the opposite message from the first claim.
