I want to know the answer to the following question:
Approximately how long did Napoleon take to prepare another Danube crossing after his defeat at Aspern-Essling?
All the background I'm provided with is that "The French were too exhausted to pursue the Austrians immediately, but Napoleon eventually caught up with Charles at Znaim and the latter signed an armistice on 12 July.". Is that enough to answer the question?
Answer: no
