Question

7th grade settings help please

Answer 1

Nick stepped off the bus and walked into the bus station. He had never seen a building so enormous, with so many buses arriving and departing from dozens of gates. Everywhere he looked there were lines of people and piles of luggage, and he wondered what the weird smells could be. He had to get out of here fast, or he thought he might be sick to his stomach.
Nick spotted an escalator across the floor and hurried over, climbing on carefully as he looked up toward the next floor. There were even more people walking fast through the terminal, and more smells competing with each other—donuts, he thought, and buttered popcorn, and maybe pizza, too. He had to get out of here fast, but it was all so confusing and crowded.
At last, Nick spotted a sign that said EXIT. He adjusted his backpack and wove through the crowd to get to the last staircase. Nick clambered up the stairs and blinked as he finally emerged into the bright sunlight. Was it possible the sun was actually brighter here in New York City than at home in his small Pennsylvania town, or was it just the light bouncing off the skyscrapers that made it seem so intense?

The city light seems brighter compared to the light in the bus station.
The city streets seem dirtier than the hallways of the bus station.
