Consider the following two Modern History questions: (1) The Montague-Chelmsford Reforms of 1919 (Government of India Act 1919) introduced which dual system of governance in provinces? (2) The Indo-Pakistani War of 1971 which led to the creation of Bangladesh was fought on which fronts? Which option gives the correct answers in the same order?

This paired question tests two independent historical relationships and requires both to be correct in the stated order. Under Diarchy provincial subjects were divided into 'transferred' subjects (education public health) administered by Indian ministers responsible to legislatures and 'reserved' subjects (law order land revenue) administered by the Governor. This system lasted until 1935. Reading the stem closely separates Diarchy (dual rule) from other names in the period: the question tests one defined act, location or institutional decision, not overall prominence. This development forms part of the changing national movement, in which constitutional negotiation, mass mobilisation, boycott, civil disobedience and revolutionary action followed different strategies; Exact dates and organisational decisions matter because related sessions For statement two, the supported answer is Both Eastern (East Pakistan/Bangladesh) and Western fronts. The Indo-Pakistani War of 1971 was fought on both the Eastern front (East Pakistan/Bangladesh) and the Western front (Pakistan). India recognized Bangladesh on 6 December 1971. About 93000 Pakistani soldiers became prisoners of war. The wording of “The Indo-Pakistani War of 1971 which led to the creation of Bangladesh was fought on which fronts?” makes Both Eastern (East Pakistan/Bangladesh) and Western fronts decisive because the stem combines a particular date, place and political consequence rather than asking for a loose association. This development forms part of the changing national movement, in which constitutional negotiation, mass Therefore the correct ordered pair is Diarchy (dual rule) followed by Both Eastern (East Pakistan/Bangladesh) and Western fronts. An option containing only one correct component must be rejected because the stem asks for a complete two-part match. This format strengthens chronology, role discrimination and careful option comparison rather than rewarding recognition of a single familiar name.
