At a family wedding, Vikas, who is usually shy and quiet, has two drinks. Soon he is chatting freely with strangers and feels confident and happy. Which of the following best explains this change?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Ethyl alcohol depresses the brain areas that control judgment and inhibition.
Option (1) Ethyl alcohol depresses the brain areas that control judgment and inhibition. — Correct. Alcohol first holds back the brain areas that keep judgment and inhibition in check. With these held back, a shy person like Vikas becomes talkative, friendly, confident and happy.
Option (2) Ethyl alcohol first acts on the brain areas that control movement and balance. — Incorrect. Motor difficulties, such as walking unsteadily and clumsiness, come later as more alcohol is absorbed. They make a drinker less able.
Option (3) Ethyl alcohol slows down the respiratory centres in the brain. — Incorrect. Slowing of the respiratory centres is the most direct danger of a heroin overdose. It nearly paralyses breathing and does not explain a shy person turning chatty.
Option (4) Ethyl alcohol stimulates the brain areas that control mood and confidence. — Incorrect. The direction is wrong. Ethyl alcohol is a depressant: it slows down the working of the brain and spinal cord. The new confidence comes from lowered inhibition.
