Final answer:
Malala Yousafzai probably improves her English through self-study, conversation with fluent speakers, and immersion in English media, similar to others who have improved their language skills outside of a school setting.
Step-by-step explanation:
The question is about how Malala Yousafzai continues to improve her English language proficiency after being out of school. While the text does not specifically detail Malala's methods for learning English post-schooling, she likely employs similar strategies to other individuals in her situation. For instance, Malala might engage in self-study using various educational resources, practice speaking with fluent English speakers, and immerse herself in English media such as books, films, and news to enhance her language skills. Additionally, having written a book, I Am Malala: The Girl Who Stood Up for Education and Was Shot by the Taliban, and used it in educational contexts, Malala has likely had plenty of opportunity to practice and improve her English. This is comparable to the experiences of other students in the excerpts who persisted in their studies and achieved fluency in English despite various challenges.
