you are driving on a long straight road. your friend sitting next to you is sleeping soundly. he wakes up as soon as you exit the highway to stop for gas. explain what it was that caused your friend to wake up.
There are a few possible reasons that could have caused your friend to wake up as soon as you exited the highway to stop for gas. Here are a couple of explanations:
1. Change in motion: When traveling on a long straight road, the consistent motion and vibrations might have contributed to your friend falling asleep. However, as soon as you exited the highway, the change in direction, speed, and road conditions likely caused a noticeable change in the sensation. This abrupt change could have disrupted your friend's sleep and caused them to wake up.
2. Pavement quality: Highways generally have smoother pavements compared to regular roads. The smoothness of the highway, along with the monotonous scenery, may have created a more soothing and comfortable environment conducive to sleep. However, once you exited the highway, the pavement quality might have changed, leading to a rougher ride. Bumpy or uneven roads can result in additional vibrations and jolts, which could have startled your friend awake.
In summary, the combination of the change in motion and potential pavement quality when you exited the highway likely caused your friend to wake up from their deep sleep.
