Definition: You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").
Input: Paragraph- Sent 1: (CNN) -- Eight-year-old Tineyi takes my hand and leads me into her mud-thatched hut in my home village of Matau in rural Zimbabwe.
Sent 2: There, in a dark corner of the room, is a wooden bookshelf.
Sent 3: Carefully crafted by her father, it protects her word-filled treasures from the smoky fire inside the small hut where her mother cooks.
Sent 4: I smile, knowing that her father has recognized the value these books will bring to his little bookworm -- a life ahead of her with limitless opportunities.
Sent 5: It was not a life intended for many girls in Africa.
Sent 6: As a cattle-herding tomboy, I was bound to follow in the footsteps of generations of women before me: early marriage, illiteracy and poverty.
Sent 7: Back then, most kids in my village never had a chance to attend pre-school because it didn't exist.
Sent 8: Instead, we would spend hours chasing birds and monkeys from our parents' fields.
Sent 9: Gold mines and urban factories employed men, while women remained at home to look after their children.
Sent 10: The more men could read and write, the better their chances of being employed and able to provide for their family.
Sent 11: As a result, families wanted to educate their sons, who became village role models.
Sent 12: Without an education, how could girls compete?
Sent 13: How could they become role models, too?
Sent 14: That was more than 40 years ago.
Sent 15: Today, change is happening in my beloved Matau, and all across the long red dirt roads, verdant mountains and open blue skies of Africa.
Sent 16: The leaders of African countries have made education more of a priority, even for girls.
Sent 17: Now, girls can be role models.
Sent 18: Girls like me, a cattle herder who married young, and by age 18 had three children and no high school diploma. 
Question: Why did the village encourage educating the male villagers?.
