Alcohol causes:
- Loss of concentration.
- Poor coordination.
- Slower judgment.
- All of the above. ✓
Answer: D. All of the above.
Alcohol causes all of the above: loss of concentration, poor coordination, and slower judgment.
Why this is the answer
The handbook says alcohol reduces the skills you need to drive safely, naming judgment, reaction, vision, and concentration. It also says judgment is the first thing affected, that reflexes and reaction time slow down, and that a drinker has trouble judging distance, speed, and movement and trouble controlling the vehicle. Loss of concentration, poor coordination, and slower judgment each appear in that list, so every one of the listed effects is real and the choice covering all of them is correct.
Why the other answers are wrong
- A. Loss of concentration. — Loss of concentration is a real effect of alcohol, but the handbook lists other effects too, so this choice is only part of the answer.
- B. Poor coordination. — Poor coordination is a real effect of alcohol, but it is not the only one the handbook names, so picking it alone is incomplete.
- C. Slower judgment. — Slower judgment is a real effect of alcohol, yet the handbook shows drinking also harms concentration and vehicle control, so this choice leaves things out.
Remember it
When a question lists several effects that all show up in the handbook's alcohol paragraph, look for the choice that covers the whole list.
