Explanation:

Saheb, the protagonist of the story "The Last Lesson", was forced to become a ragpicker due to acute poverty. The following points explain the reasons behind this:

Family background: Saheb hailed from a poor family who struggled to make ends meet. His father was a sickly man who could not provide for the family. Saheb's mother worked as a maid in the houses of the affluent to earn a living. Despite their efforts, the family barely managed to survive.

Limited education: Saheb had limited access to education due to financial constraints. He had to drop out of school and start working to support his family. This limited his career prospects, and he had to settle for odd jobs to earn a living.

Lack of opportunities: Saheb's limited education and lack of skills left him with few job opportunities. He had to resort to menial jobs like ragpicking to earn a livelihood. This was not his choice but a necessity to provide for his family.

Peer pressure: Saheb's peers were also from similar backgrounds, and many of them were also ragpickers. This peer pressure forced Saheb to follow suit and become a ragpicker.

Conclusion: In conclusion, Saheb's poverty, limited education, lack of opportunities, and peer pressure forced him to become a ragpicker. It highlights the harsh reality of the lives of the underprivileged in society and the need for equal access to education and opportunities for all.
