What is the first thing affected by alcohol consumption?
- Reaction time.
- Judgment. ✓
- Slurred speech.
- Vision.
Answer: B. Judgment.
The first thing affected by alcohol is judgment.
Why this is the answer
The handbook says alcohol harms several driving skills, including judgment, reaction, vision, and concentration, and then states plainly that a person’s judgment is the first thing affected after drinking. That is why judgment is the correct choice. The same passage says alcohol slows reflexes and reaction time and reduces clear vision, but it does not put those ahead of judgment. So even though drinking also changes how quickly you react and how well you see, the first change the handbook names is your ability to judge.
Why the other answers are wrong
- A. Reaction time. — Alcohol does slow reaction time, but the handbook identifies judgment as the first skill affected, not reaction time.
- C. Slurred speech. — Slurred speech is not named in these passages as the first effect; the handbook points to judgment.
- D. Vision. — Alcohol reduces clear vision, but the handbook says judgment is affected before vision.
Remember it
Remember: the first thing alcohol takes away is the clear-headed call, not the quick reflex.
