Answer (1)
Answer:a. We will become more alert.Yawning helps bring more oxygen into our brain and body. This oxygen helps us become more awake or alert, especially when we’re tired or bored. Scientists say that yawning helps cool down the brain so it can work better. That’s why after yawning, we often feel a little more awake or focused.
