Reasons girls were not sent to school:
Girls were not sent to school due to several reasons, including societal norms, economic constraints, and lack of awareness about the importance of education for girls.

Societal norms:
- In many societies, girls were expected to stay at home and take care of household chores instead of pursuing education.
- There was a belief that girls did not need education as their primary role was to get married and raise a family.
- Gender stereotypes and discrimination also played a significant role in limiting girls' access to education.

Economic constraints:
- Families facing financial difficulties often prioritized the education of boys over girls, as they believed that boys would have better job opportunities in the future.
- Some families could not afford to send all their children to school, and girls were often the ones left out due to traditional gender roles.

Lack of awareness:
- Many parents, especially in rural areas, were not aware of the benefits of educating their daughters.
- Lack of access to information and resources about the value of education for girls contributed to the low enrollment rates of girls in schools.
- Cultural beliefs and practices also played a role in perpetuating the idea that girls did not need education as much as boys did.
In conclusion, addressing these barriers through advocacy, policy changes, and community engagement can help increase girls' access to education and promote gender equality in schools.
