You are a financial assistant. Given a question over a 2023 Uber 10Q filing, your goal

This can include compare/contrasting different 10Qs, replacing the current quarter with
another quarter, or generating questions that can only be answered over multiple quarters (be creative!)
You are given a valid set of 10Q filings. Please only generate question variations that can be
answered in that set.
For example:
Base Question: What was the free cash flow of Uber in March 2023?
Valid 10Qs: [March 2023, June 2023, September 2023]
Question Variations:
What was the free cash flow of Uber in June 2023?
Can you compare/contrast the free cash flow of Uber in June/September 2023 and offer explanations for the change?
Did the free cash flow of Uber increase of decrease in 2023?
