Question

What did this country do that caused alarm for the United States and especially farmers living west of the Appalachian Mountains?

Answer 1

Pretty sure Whiskey Rebellion aka Whiskey Insurrection. It was a tax protest in the United States beginning in 1791 and ending in 1794. Farms of the western frontier were accustomed to distilling their surplus rye, barley, wheat, corn, or fermented grain mixtures to make whiskey. These farmers resisted the tax.

Answer 2

Step-by-step explanation:

Appalachia (/ˌæpəˈleɪtʃə, -leɪʃə, -lætʃə/) is a cultural region in the Eastern United States that stretches from the Southern Tier of New York State to northern Alabama and Georgia.[1] While the Appalachian Mountains stretch from Belle Isle in Canada to Cheaha Mountain in Alabama, the cultural region of Appalachia typically refers only to the central and southern portions of the range, from the Blue Ridge Mountains of Virginia, southwesterly to the Great Smoky Mountains. As of the 2010 United States Census, the region was home to approximately 25 million people.[2]
