The answer is that those scientists who study the customs of a group of people are known as a Anthropologists.
The main idea of the biography is that Dorothy deserves credit as a pioneer for her accomplishments at NASA. The sentence that confirms this is:
“…Vaughan was both a respected mathematician and NASA's first African-American manager.”
We can arrive at this answer because:
- Dorothy Vaughan's biography wants to show why she was a scientist and someone so important to American society.
- In addition to having contributed a lot to the work of NASA, Vaughan was a pioneer in that institution.
- That's because, NASA was an institution dominated by white people, who had more access to higher education and administrative positions.
- However, Dorothy Vaughan became the first African-American manager that NASA had, in addition to being one of the first women to occupy this position, which makes her a pioneer.
As the central idea of a text is the main subject that the text intends to address, we can affirm that Dorothy Vaughan's pioneering spirit is the central idea of her biography.
