The Correct Answer and Explanation is:
Based on the calculations for each beverage, the correct answer is:
A. Las cuatro contienen, aproximadamente, la misma cantidad de alcohol puro.
Explanation
The question asks to compare the amount of pure alcohol in four different standard alcoholic drinks. To determine the correct answer, we must calculate the volume of pure alcohol in each beverage. This is done by multiplying the total volume of the drink by its percentage of alcohol by volume (ABV).
Let’s break down the calculation for each drink listed:
- Cerveza (Beer): The serving is 355 mL with 5% alcohol. The calculation is 355 mL multiplied by 0.05, which equals 17.75 mL of pure alcohol.
- Refresco a base de vino (Wine Cooler): This serving is also 355 mL with 5% alcohol. The calculation is identical to the beer: 355 mL multiplied by 0.05, resulting in 17.75 mL of pure alcohol.
- Licor (Liquor): The serving is 45 mL with 40% alcohol. The calculation is 45 mL multiplied by 0.40, which equals 18.0 mL of pure alcohol.
- Vino (Wine): The serving is 145 mL with 12% alcohol. The calculation is 145 mL multiplied by 0.12, resulting in 17.4 mL of pure alcohol.
When we compare these results (17.75 mL, 17.75 mL, 18.0 mL, and 17.4 mL), it becomes clear that all four amounts are very close to one another. The small variations are minimal. This concept illustrates the principle of a “standard drink,” where different types of alcoholic beverages in their typical serving sizes contain roughly the same quantity of ethanol. Therefore, the statement that all four drinks contain approximately the same amount of pure alcohol is the most accurate description. Options B, C, and D are incorrect because while there are minor differences, they are not significant enough to be the primary takeaway. The key point is their similarity, not their slight variations.
