Which qualities are negatively affected by alcohol consumption?

  1. Judgment
  2. Ability to reason
  3. Vision
  4. All of the above ✓

Answer: D. All of the above

All of the above — alcohol harms judgment, the ability to reason, and vision.

Why this is the answer

The handbook says that when a person drinks alcohol, one of the first effects is losing judgment and having sight impaired. It adds that a person's ability to reason can all but disappear, and describes alcohol as a depressant that affects coordination, judgment, and perception. Since judgment, reasoning and vision all appear in the text as things alcohol damages, the choice covering all three is the right one.

Why the other answers are wrong

Remember it

Remember the handbook's short list: drinking costs you a clear head, a steady hand and an observant eye, so pick the answer that keeps all three in view.
