Alcohol causes:
- Loss of concentration.
- Poor coordination.
- Slower judgment.
- All of the above. ✓
Answer: D. All of the above.
Alcohol causes all of the listed effects: loss of concentration, poor coordination, and slower judgment.
Why this is the answer
The handbook describes alcohol as a depressant that affects coordination, judgment, perception, and emotional state. It also says alcohol impairs judgement and sight, slows reactions, and can make a person's ability to reason nearly disappear. The chapter's broader point is that alcohol affects the mental and physical skills needed to drive and react safely. Because these effects show up together rather than one at a time, the choice that includes loss of concentration, poor coordination, and slower judgment fits better than picking just one effect.
Why the other answers are wrong
- A. Loss of concentration. — Loss of concentration is only one part of the picture; the handbook also says alcohol affects coordination and judgment.
- B. Poor coordination. — Poor coordination is real, but it is not the only effect; alcohol also impairs judgment and other driving skills.
- C. Slower judgment. — Slower judgment is real, but the handbook describes alcohol as affecting coordination and other driving skills as well, so this choice is incomplete.
Remember it
Picture alcohol dimming several dials at once—coordination, judgment, and focus—rather than just one.
