Read the following passage carefully and answer the questions that follow.
The development of nationalism in the third world countries, as is well known, followed a very different trajectory from that in the advanced capitalist countries. In the latter it was a part of the process of the emergence of the bourgeois order in opposition to feudalism, while in the former it was a part of the anti-colonial struggle. The impact of colonialism, though it differed across countries, had on the whole been in the direction of transcending localism and unifying supra-local economic structures through the introduction of market relations. The struggle against colonialism, consequently, took the form of a national struggle in each instance in which people belonging to different tribes or linguistic communities participated.
The colonial power in each instance attempted to break this emerging national unity by splitting people. The modus operandi of this splitting was not just through political manipulation as happened in instances in Angola, South Africa and many other countries; an important part of this modus operandi was through nurturing the historiography that justified the absence of any overarching national consciousness. The national struggle, the national movement were given a tribal or religious character, and were portrayed as being no more than the movement of the dominant tribe or the dominant religious group for the achievement of narrow sectional ends. But the coming into being of a national consciousness at a supra-tribal, supra-local and supra-religious level sought deliberately to subvert this very consciousness by using the same forces which it had objectively undermined.
