Which act may be linked to fatigue or boredom and can be addictive when others do it?

• A. Yawning
• B. Sneezing
• C. Laughing
• D. Stretching

Answer: (A)

Yawning is commonly tied to tiredness or boredom, and it has a contagious quality—watching someone yawn or even thinking about yawning can trigger yawns in you. This contagious effect comes from how our brains mirror others’ actions, so yawning can spread in a group like a whisper chain, which can feel like you’re “addicted” to it when others are doing it. The other acts don’t fit as neatly: sneezing isn’t about fatigue or boredom and isn’t typically contagious in the same social way; laughing stems from amusement rather than fatigue; stretching is a neutral movement that doesn’t specifically signal tiredness or spread from person to person.
