Final answer:
The question seems to contain inaccuracies regarding Dr. K.I. Singh's political history in Nepal. A direct answer cannot be provided due to the lack of relevant information connected to the reference provided about Dr. Manmohan Singh and Amartya Sen.
Step-by-step explanation:
The question seems to be rooted in confusion and potentially some historical inaccuracies regarding Dr. K.I. Singh and the specific details of his brief tenure as Prime Minister of Nepal. Dr. K.I. Singh was a Nepali political figure who, at various points in his career, participated in revolutionary activities against the ruling Rana dynasty. After the fall of the Rana regime and the establishment of a democratic government in 1951, Singh became critical of the new leadership's failure to implement promised reforms and briefly seized power in 1957.
His tenure as prime minister was short-lived, and he was soon exiled. However, the available reference connected to Dr. Manmohan Singh and Amartya Sen does not relate to the question about Dr. K.I. Singh or the political history of Nepal. Therefore, a satisfactory answer is not possible without additional relevant information on Dr. K.I. Singh.
