Which of the following factors affect an individual's absorption of alcohol?
- Weight ✓
- Height
- Intelligence
Answer: A. Weight
Body weight is the factor among these that affects how alcohol is absorbed and how high your blood alcohol concentration (BAC) reaches.
Why this is the answer
The handbook explains that alcohol enters your bloodstream and that BAC measures how much alcohol is in it. It then presents a table of BAC estimates built on three things: how many drinks you have had, your gender, and your body weight. Because body weight is one of the inputs the handbook uses to estimate BAC, it is the listed factor that makes a difference from person to person.
Why the other answers are wrong
- B. Height — Height is not one of the things the handbook uses to estimate BAC, so it plays no part in how alcohol affects you.
- C. Intelligence — Intelligence has nothing to do with how alcohol gets into your bloodstream, and the handbook never lists it among the factors behind the BAC table.
Remember it
When you picture the BAC chart, picture three columns: drinks, gender, weight. If a factor is not one of those three, it does not belong in the answer.
