All I know is part A to the question :The geography of India greatly influenced the location of early settlements on the subcontinent. Both the Indus and the Ganges rivers carried rich silt from the mountains to the plains. When the rivers flooded, the silt spread over the plains and made the soil in the river valleys fertile for farming.
The answer is 2: to increase the amount of land available for agriculture.
Reason:
If I remember correctly from Geography last year that is called terrace farming. Common practice in hilly areas where you would be unable to plant crops. Instead, they flatten that out and have “steps” that gives them flat land to grow crops, often rice.
The storming of the Bastille in 1789 kickstarted the period of violence that defined the French Revolution. That was a pretty big turning point, as the serfs finally attempted to use violence against the nobility and aristocrats.
