Concentrated ownership of land by minority elite
It's interesting that you posted your question in the history section of Brainly. It qualifies in the category of "Big History," as some have termed it. That term was coined by the scholar David Christian, whom I met once at a conference where he was a presenter. His idea was that we look at "history" not just as what has happened in the recorded records of human beings, but look back at all that has occurred in the history of the universe. So the "Big History" concept incorporates the story of evolution into its account of things.
As far as your specific question, a key indicator of primates' adaptability is that you see primates living in all sorts of different regions on the planet. Snow monkeys live in cold regions of Japan where snow covers the ground many months of the year. Howler monkeys live in the tropical rainforests of Brazil. And there are other primates of all sorts in all sorts of climates and conditions. That shows the adaptability of primates to survive and thrive in various circumstances.
The main reason behind the Sepoy Rebellion of 1857 is actually multifaceted. The direct cause was a change in the use of the weapons Britain provided to Indian sepoys, basically soldiers fighting for the British. The British began to implement a new kind of grease for their guns that was cheaper than the previous grease. However, this grease was a combination of pig fat and cow fat. In order to open these packets of grease, one had to use their teeth. Remember that India's major religions at the time were Hindu and Islam. The Hindu sepoys were appalled by the notion that they would use the sacred cow, and the Muslim sepoys refused to bite open the packets because pork is taboo to them. This whole incident combined with general resentment towards British rule of India, and the fighting began.
