The correct answer to this open question is the following.
Though the revolt of 1857 was suppressed by the British within a year of its outbreak, it had a far-reaching consequence. It represented the first major organized movement to demand freedom for the Indian people against the government of Great Britain. It marked the foundation of future independent movements against the British presence in India.
The British East India Company had been ruling the Indian territory and the native people were tired of it, trying to get rid of the White English and what they considered their injustices. It was not easy for the British Army to stop the revolt, but their modern weaponry and the military organization was too much for the rebels.
