Read the passage given below carefully and answer the questions that follows:
Earlier, Lal Bahadur Shastri had resigned from the position of Railway Minister accepting moral responsibility for a major railway accident. Shastri was the country’s Prime Minister from 1964 to 1966. During Shastri’s brief Prime Ministership, the country faced two major challenges. While India was still recovering from the economic implications of the war with China; failed monsoons, drought and serious food crisis presented a grave challenge. As discussed in the previous chapter, the country also faced a war with Pakistan in 1965. Shastri’s famous slogan ‘Jai Jawan, Jai Kisan’, symbolised the country’s resolve to face both these challenges. Shastri’s Prime Ministership came to an abrupt end on 10 January, 1966, when he suddenly expired in Tashkent, then in USSR and currently the capital of Uzbekistan. He was there to discuss and sign an agreement with Muhammad Ayub Khan, the then President of Pakistan, to end the war.
Q. What was the tenure of Shastri as a PM of India?
