<span>Antibiotics are of no benefit in trying to treat the common cold or influenza (or any other virus infection). Nothing will happen because antibiotics aren't effective on viruses, which are the microorganisms responsible for the common cold. Antibiotics can kill only bacteria and are used for infections caused by bacteria

The answer to the question is D
I think the first one should be 107-125 because I found the average maximum hart rate for 47 year old male is 173-176bbp.
I think the second one is heart health zone. I found that this zone is when your hart rate is 50-60 percent of its maximum hart rate and the maximum hart rate for a 42 year old male is about 178.
the third one seems to be right
I think the fourth one should be glycogen depletion since it can't easily be replaced.
I would go with C. Because it's a study printed by the American Health Association...Pretty sure they know about health..lol
