Why is the time period important while studying causes of deforestation?

Correct answer: Because railway and plantation expansion became rapid in the nineteenth century

Correct answer: A — railway and plantation expansion became rapid in the nineteenth century. Historical causes must be placed in time because different demands became important at different moments. During the nineteenth century, the expansion of railways increased the need for wooden sleepers and fuel, while plantations required large areas of cleared land for commercial crops. Studying the period helps us connect each cause with the changes taking place then. A is correct because it gives historically relevant developments and a time frame. B is wrong because history is fundamentally concerned with change over time. C is wrong because deforestation was a gradual process, not an event completed in one day. D is wrong because colonial rule lasted far longer than one week. Memory cue: ask “what changed, and when?” before explaining a historical cause.
