Answer:
Malala Yousafzai, the Pakistani activist for female education and Nobel Peace Prize laureate, refers to the "sisters" in her memoir "I Am Malala: The Story of the Girl Who Stood Up for Education and Was Shot by the Taliban." The term "sisters" is used to refer to the girls in her community who also attend school and share her passion for education.
The "sisters" face numerous challenges, including opposition from the Taliban, who forbid girls from attending school, and from local conservative communities, who view girls' education as unnecessary or even inappropriate. In addition, poverty and lack of access to resources such as textbooks, transportation, and safe schools, also pose significant obstacles to girls' education.
Malala writes, "It was a miracle that I had made friends with these girls from the other side of town, girls who knew nothing of the Khushal School or its good reputation, and who had come so far, leaving their comfortable homes, to sit on hard wooden chairs in a place where they knew no one. I realized then that the challenge was not just to get girls into school, but to keep them there. Poverty, terrorism, war – all these things come in the way" (Chapter 6).
Furthermore, Malala describes the danger that the "sisters" face as they pursue their education. She writes, "We were scared of everything, afraid to even breathe too loudly. The Taliban had already blown up more than a hundred girls' schools. I knew we were next" (Chapter 7).
In summary, the "sisters" Malala describes in her memoir are the girls in her community who also attend school and face numerous challenges in pursuing their education, including opposition from the Taliban, conservative communities, poverty, and danger.
