Final answer:
Borrowing a lot of money to pay for the war will cause a massive debt for England.
Step-by-step explanation:
The financial problem that borrowing a lot of money to pay for the war is going to cause for England is a massive debt. The war generated a significant amount of debt for Great Britain, which proved to be the most serious issue facing the country. This debt would need to be paid off, and various measures, such as enforcing trade laws and raising revenue through taxation, would be implemented to address the financial burden.
