Step-by-step explanation:

This investment in human capital can improve economic growth as it makes a workforce more productive and can lead to technological innovations.

However, the direct impact of Maggie's education is specifically on her own human capital, and not on physical capital or technology itself unless she specifically creates or invests in these areas as a result of her education.
