premise: John Thomas Harris (May 8, 1823 – October 14, 1899) was a nineteenth-century politician, lawyer and judge from Virginia. He often referred to after the American Civil War as "Judge Harris", even after his election to Congress. He was the first cousin of John Hill.
hypothesis: John Thomas Harris's last job was Congressman. 
reason: It doesn't specify that Congressman was his last job. It may have been difficult because Congress was the last thing mentioned.
