D. The end of the cold war
In an era when NASA is led by an African American man (Administrator Charles Bolden<span>) and a woman (Deputy Administrator </span>Dava Newman<span>), when </span>recent NASA Center Directors<span> come from a variety of backgrounds, it's easy to overlook the people who paved the way for the agency's current robust and diverse workforce and leadership. Those who speak of NASA's pioneers rarely mention the name Dorothy Vaughan, but as the head of the NACA's segregated West Area Computing Unit, Vaughan was both a respected mathematician and NASA's first African-American manager. I learn this from class and from a book I hope this helps
