So if this argument was given it would be wrong:

*If I go to the store then I buy milk.

I bought milk

I went to the store*

because I could have bought milk elsewhere besides the store?

ON 13.2 the subject-predicate was: people (subject) are planning a trip(predicate). On 14.2 the S/P was: the puppies (subject) were (predicate.

My question is, why is planning a trip included in the predicate for 13.2 and why is rescued (which comes after were) not in the predicate for 14.2?
