Compound Condition? Yes or No?

How is it that for the second principle you do not write the S condition as Mail Correctly Addressed & Not Arrive in 2 Days or Less? How did you know to combine and make one condition? If feel with the practice problems from S&N and these for Quantifiers it is not clear or consistent as to when you need or don't need a compound condition.

@Meredith,

Happy to help. You could technically diagram that second sentence as a
having a compound sufficient condition f you wanted to. It's like
diagramming all red dogs are nice as

Red dogs - >nice

vs.

Dogs + red - >nice

These basically mean the same thing. It can be helpful to make
multiple sufficient conditions when you have two or more large clauses
in the sufficient condition. When you just have adjectives or short
phrases that are modifying one thing (as is the case with correctly
addressed mail that takes longer than two days), it's generally
easiest to write that as a single sufficient condition.

CA 2+ - >Damaged

You could also write this as

CA and 2+ - >Damaged

Regardless of which way you choose to write it, you will arrive at the
same correct answer choice because those statements are essentially
telling us the same thing.

Does this make sense? Let us know if you have any other questions!
