premise: Russell James Liberman (September 12, 1945 - September 9, 1977) was a United States drag racer from Pennsylvania, known as "Jungle Jim". He was named #17 on the list of the Top 50 NHRA drivers. Liberman was known for driving backwards at 100 mph (160 km/h) after doing his burnout.
hypothesis: Russell James Liberman is currently alive.
reason: It's definitely incorrect because he died in 1977. This type of question is difficult for the system because it is not good at understanding death dates and the real world implications of what it means for someone to be dead.
