Shays's Rebellion in 1787 was primarily in response to increased taxes and the seizure of farms. The rebellion was driven by farmers in Massachusetts who were facing economic hardship, high taxes, and the threat of losing their farms due to debt. The other options, such as the expansion of territories and the Northwest Ordinance, were not direct causes of Shays's Rebellion.
So, the correct responses are:
- Seizure of farms
- Increased taxes
