Final answer:
In context of alcohol absorption, anger does not increase absorption, while higher alcohol concentration and carbonation do.
Step-by-step explanation:
The subject of this question falls under Health education, and it appears to be targeted at the High School level. The question pertains to factors that affect the absorption rate of alcohol in the human body. Of the options given, anger is the factor that does not increase the absorption of alcohol. Factors such as higher alcohol concentration in the drink do increase absorption because a higher concentration can speed up the rate at which alcohol enters the bloodstream. The presence of carbonation can also increase the absorption rate, as it may speed up the passage of alcohol from the stomach to the small intestine. Nicotine, which is mentioned in the context of nicotinamide adenine dinucleotide (NAD) related to the metabolism of alcohol, is not directly related to the absorption rate of ingested alcohol, but rather its metabolic rate. Therefore, neither nicotine nor anger directly increases alcohol absorption.
