Well both of theese dont make sense so i reasearched your question and found theese 3 options :A.Blood alcohol concentration is affected by factors such as body size and gender. B.Drinking coffee and exercising will lower your blood alcohol concentration. <span>C.The higher the blood alcohol concentration, the more severe the hangover will be.
So im guessing C. if this in your question :)
If you need more help in this subject feel free to pm me have a nice evening</span>
It may be either Disagreements or Intractable Situations. I'm not completely sure, sorry. I'd wait for another to come answer your question just to be safe.
