1) I think it is A as it explains more about the story "to build a fire" the man really did have foolish decisions.
D - it wasn't your dog that barked. This one is correct as it uses the possessive form of you (your dog - the dog belongs to you)
The others are incorrect. A (should be Aunt Carment and ME) - B (should be MY brother David), C (should be Jack and HER)
Answer:
i think its A. (I might be wrong)
