A thunderstorm on the beach.<br>While staying at their beach hotel, Ben and Dani witnessed a storm. One night just after the sun went down, it became very windy. They sat on the balcony and watched as lightning began to flash. The sky turned a beautiful shade of purple as thunder crashed. It was exciting and scary for them to watch the storm quickly pass.
The storm stayed in the area for several hours
It is incorrect because it says the storm quickly passed. A several hour storm is not "quickly". I don't think the system has a certain number of minutes/hours associated with something being quickly over
