I think the answer is: A - balanced
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:
Differences in facial expression
Explanation:
There are 7 types of facial expressions each of which has its own uniqueness.
Difference in facial expressions do not hinder non verbal communication because facial expressions have proven to be an effective means of communication in the absence of a common language.
Though, it can be a very strange "exercise" and energetic gesturing but all emotions shared via facial expressions are universal and there won't be any difficulty in understanding them.
Answer:
The same structure, in indirect or reported form, would be:
The principal will say that rules have to be followed at any cost.
Explanation:
<u>When reporting what someone said, we must change the verb tenses according to when the line was said. If there are any pronouns in the sentence, those may also need to be changed to match the speaker - for instance, if a man said something about himself, we should change "I" for "he". We also change time expressions, such as substituting "today" for "that day".</u>
<u>Not much changes in the sentence we are transforming here since the line inside the quotation marks does not present time expressions or pronouns. Another reason for that is the verb tense. Because it is "will say", which is a future, we do not have to change the verb tense inside the quotation marks.</u>
Just to make it clearer, imagine that the principal already said that: The principal said, "Rules have to be followed at any cost." Now the tense is in the past, "said". In this case, we should also change the tense inside the quotation marks. It would be: The principal said that rules had to be followed at any cost.
