What problem faced President George Washington during the Whiskey Rebellion of 1791–1794?

a how to avoid paying unpopular duties to England for foreign whiskey
b how to prevent western farmers from drinking too much whiskey
c how to encourage western farmers to send their whiskey to Eastern cities
d how to collect an unpopular federal tax from unwilling farmers

The problem faced by President George Washington during the Whiskey Rebellion of 1791-1794 was option D: how to collect an unpopular federal tax from unwilling farmers.

To understand this and arrive at the correct answer, we can break down the process of elimination.

Option A: "How to avoid paying unpopular duties to England for foreign whiskey" refers to a different issue, unrelated to the Whiskey Rebellion. The Whiskey Rebellion was a domestic conflict within the United States, not an issue of international trade.

Option B: "How to prevent western farmers from drinking too much whiskey" is not the problem that President George Washington faced during this rebellion. The Whiskey Rebellion was not driven by concerns over excessive alcohol consumption but rather by opposition to the federal tax on whiskey production.

Option C: "How to encourage western farmers to send their whiskey to Eastern cities" is also not the problem faced by President George Washington. The rebellion was not about promoting the distribution of whiskey; it was a response to the taxation of whiskey production.

Therefore, the correct answer is option D: "How to collect an unpopular federal tax from unwilling farmers."
