Final answer:
We cannot determine the equivalent number of standard alcoholic drinks without knowing the alcohol content of the beer and wine.
Step-by-step explanation:
To determine the equivalent number of standard alcoholic drinks, we need to know the alcohol content of each type of beverage. A standard alcoholic drink is typically defined as containing 14 grams (0.6 ounces) of pure alcohol. However, since we don't have the alcohol content of the beer and wine Jenna consumed, we cannot accurately determine the number of standard drinks. Different types and brands of beers and wines can vary in alcohol content, so we need that information to make an accurate calculation. Without this information, it is not possible to determine the correct answer from the given options.
