That's why empowering women is now one of the main solutions for feeding the world. Globablly, most countries have achieved a birth rate at replacement levels, about two children per woman. But in sub-Saharan Africa, the [birth] rate is 5.6 children per woman, largely because girls are not aware of reproductive choices and drop out of school at a young age and have kids. [Birth] rates are highest in countries where women don't have access to birth control or maternal and child health care. Babies often die before they turn five years old, and mothers overcompensate in family planning in hopes that at least a few kids will survive to adulthood. Unless the status of women changes in sub-Saharan Africa, we're going to have a lot more than one billion hungry by midcentury.

How does the third sentence develop the idea that the lack of education can lead to higher birth rates in sub-Saharan Africa?

A. It explains that the birth rate is higher because women are unaware of birth control and drop out of school because they started having children.
B. It explains that women in most countries have two children per woman, which achieves a birth rate at replacement levels.

C. It lays out the theory that the main solution to feeding people is to educate women so they have fewer children.

D. It suggests that because of a lack of child health care, women give birth to more children because most die before the age of five.
