Saying, "I'll wake up with a headache if I drink tonight," is an example of using an excuse to remain alcohol-free .because the person is trying to avoid alcohol so he is making an excuse so that if someone asks him to drink alcohol he refuses by saying that if I drink I'll wake up with a headache
The answer would be true because first of all u can wake up with a headache if u drink alcohol but that is a good excuse to stay drug alcohol free if someone asks u to drink
The answer would not be a or b so lets cross those out relaxing puts less strain and gives the body the extra push that it needs breathing through your nose isn't really going to do much so I would say the answer will be C)
