premise: Kota Ramakrishna Karanth (born May 1, 1894) was an Indian lawyer and politician who served as the Minister of Land Revenue for the Madras Presidency from March 1, 1946 to March 23, 1947. He was the elder brother of noted Kannada novelist K. Shivarama Karanth.
hypothesis: Kota Ramakrishna Karanth served as the Minister of Land Revenue for two years.
reason: He only served for one year, not two years. I think the system found it difficult because it had the actual dates, not the length of time he served.
