Martin began drinking alcohol during college. he now consumes 6 to 12 bottles of beer each evening. when asked why he drinks so much, martin replied, "it takes at least a six-pack to feel anything." martin's increased need for alcohol to achieve the same effects is an example of:

tolerance

Explanation:

Alcohol tolerance increases when there´s steady chronic alcohol consumption. The drinker may develop tolerance to some alcohol's effects, meaning alcohol produces a lesser effect than before.

Decreased sensitivity may lead to increasing the amount of alcohol to produce the same outcome. Therefore, alcohol tolerance could lead to, or be a symptom of, alcoholism.

this doesn't support enough information to answer the question.
