This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Let me give you an example: Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.
The answer to this example can be: When was the French and Indian War?
Here is why: This question is based on the following sentence in the passage- The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. You can ask questions like this one about dates, years, other numerals, persons, locations, noun phrases, verb phrases, adjectives, clauses etc. which exist in the paragraph.

OK. solve this:
Confederates held East Tennessee despite the strength of Unionist sentiment there, with the exception of extremely pro-Confederate Sullivan County. The Confederates, led by General James Longstreet, did attack General Burnside's Fort Sanders at Knoxville and lost. It was a big blow to East Tennessee Confederate momentum, but Longstreet won the Battle of Bean's Station a few weeks later. The Confederates besieged Chattanooga during the Chattanooga Campaign in early fall 1863, but were driven off by Grant in November. Many of the Confederate defeats can be attributed to the poor strategic vision of General Braxton Bragg, who led the Army of Tennessee from Perryville, Kentucky to another Confederate defeat at Chattanooga.
Answer:
Which county in East Tennessee was more supportive of the Confederacy than its neighbors?
