Thomas E. O'Donnell (1841 – c. 1875) was one of the driving forces in the New York City draft riots, when he was 22 years old. He was a public opponent of the draft, so he was promptly arrested. Though his jail time is unknown, it is known that he died at age 34 due to heart problems.
Thomas E. O'Donnell spent 5 years in prison.
This neither definitely correct nor definitely incorrect because in the context the amount of jail time is unknown so it could be true. I think it was difficult for the system because the context says it is unknown which makes it false.
