Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
During a family vacation, Sarah, David, and their parents visit an amusement park with four roller coasters: Red Rocket, Blue Bolt, Green Goliath, and Yellow Yawper. The family splits up, with Sarah and David going to ride the Red Rocket first. Their parents go to the Blue Bolt. After riding the Red Rocket, Sarah goes to get ice cream while David rides the Green Goliath alone. When Sarah finishes her ice cream, she wants to find David. Which roller coaster will Sarah check first, and where does David think Sarah might be looking for him? Provide a brief response.

### Response:

Sarah will most likely check the Green Goliath first because she knows that is where David went after they split up. Since they have already ridden the Red Rocket together, it would make sense for her to look for him at the last place he said he was going.

As for David, since he rode the Green Goliath alone after Sarah went for ice cream, he might expect Sarah to look for him there. However, if some time has passed and he assumes she saw him riding it or knows he has finished, he might think she will look for him at one of the remaining coasters that they haven't ridden yet - possibly the Blue Bolt where their parents started, or the Yellow Yawper. If David believes Sarah would predict he would continue riding coasters, he might also think she'd head to the Yellow Yawper, the last one left untried by them.
