For questions 1 through 4 your complex statement is "Dogs are mammals."

A- Something is a dog
B-Something is a mammal
C-Dog

2-B
2. What is q?
A-Something is a dog
B-Something is a mammal
C-Mammal
D-Dogs are

3.F
3. "If something is not a dog, then it is not a mammal" is the:

A-Contrapositive

4.D

4. ~q => ~p for this statement is:
A-If it is a dog, then it is a mammal.

A-Converse
