Nina [5.8K]
<h2>Hello!</h2>

The answer is:

The man did consume two standard drinks in two hours.

<h2>Why?</h2>

According to the standard drink conversion, we know that each 12 ounce beer we have one (1) standard drink, and each 1.5 ounce shot of liquor, we have another standar drink.

Calculating we have:

DrinksConsumed=12Oz(Beer)+1.5Oz(Liquor)=1StandardDrink+1StandardDrink\\\\DrinksConsumed=1StandardDrink+1StandardDrink=2StandardDrinks

We have that the man did consume two standard drinks in two hours.

Have a nice day!
