Question

make a logical inference about why yawns are contagious. In 3–5 sentences

Answer 1

Yawns are thought to be contagious largely due to social and neurological factors. When we see someone yawn, it may trigger mirror neurons in our brain, prompting us to mimic the behavior as a form of social bonding or empathy. This response could have evolved as a way to synchronize group behaviors, promoting alertness or readiness in social animals. Additionally, yawning might signal a change in alertness or state of fatigue, encouraging others to respond similarly, thereby enhancing group vigilance. Overall, the contagious nature of yawns may reflect both biological and social mechanisms that enhance group cohesion and communication.
