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.

Answer: B
Explanation: C and D are more obviously incorrect, and A’s pronoun would have to be changed to “their”
In Afghanistan, Amir and Baba’s relationship is strained. Baba doesn’t fully accept Amir, he views him as different, and the lack of similarities he sees from himself to Amir make Amir seem like an outsider. For example, Baba is a strong, brave man, while Amir chows signs of cowardice in many aspects of his life. In Afghanistan, there is little to no communication between the two characters, and Amir must find comfort in Rahim Khan, instead of his own father.In America, all of this changes. This change in their relationship could be a metaphor for the change in Afghanistan, the change of cultures, or the internal change Amir will go through, but it is a change regardless. The first this we see change is Amir takes a much larger role in his father’s life. Now he must watch over his father, like when Baba destroys the gas station store, and when he eventually gets cancer. Amir’s accomplishments seem to make Baba more proud, also. Back in Afghanistan, they only time Baba was ever really proud of Amir was when he won the kite tournament, a feat that Baba was more interested in Amir winning than Amir was. But in America, Amir’s accomplishments, like graduating form high school and going to college, are looked upon highly by Baba. Lastly, the communication barrier between Amir and Baba is finally broken down, the two seem to be able to talk more freely to each other, and Baba seems to respond to Amir more openly then he ever would have in Afghanistan.
