Shun and Maki did some research on education.

Shun: What is the most impressive quote on education you found?
Maki: I like Nelson Mandela’s words: “Education is the most powerful weapon which you can use to change the world.” How about you?
Shun: I chose Malala Yousafzai’s comment: “One child, one teacher, one book, one pen can change the world.”
Maki: Everyone seems to agree that education is important. But there are still about 63 million children in the world who do not go to school. That is why the United Nations chose “A Quality Education for All” as one of the SDGs.
Shun: From what I’ve found, it seems that about half of those 63 million children live in sub-Saharan Africa. Why can’t they go to school?
Maki: As far as I know, one of the main reasons is that there are not enough schools. Poor families cannot afford to send their children to school, and some parents do not even think school is necessary. Instead, they want their children to work to earn money for the family. In short, poverty is the main reason children do not go to school.
