Generate a dialogue with ChatGPT that follows a sequential pattern. Begin the conversation by posing a question, wait for the model's response, and then ask a follow-up question based on that response.
For example, you can ask the following questions one by one:

1. Ask ChatGPT to provide a brief overview of what the Crusades were and why they occurred;
2. Based on the response, inquire about the key motivations that drove individuals to participate in the Crusades;
3. Ask ChatGPT to elaborate on a specific Crusade and discuss its major events and outcomes.
