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.

Select the correct relative pronoun form the list given and complete the blank space in each of tge following sentences.

Arturiano [62]

Answer:

I will explain to you when to use these relative pronouns and then you can probably figure the answer out yourself. It's pretty simple!

Explanation:

Where: This relative pronoun refers to a place, such as the White House or the moon. "Where is my phone?"

When: This is about time. It can be at 12:00 in the morning, Tuesday, or even 1987. "This morning when the bus arrived, I wasn't ready so I missed it.

Who: This is about people. It can be soldiers, astronauts, students, etc. "The students, who were late to class, sat down 10 minutes before the final bell."

Which: This is about the difference between multiple things. For example: "Which should I use to eat dinner, the spoon or the fork?" This can also be used to talk about a place. "My house, which is very large, is a couple blocks away from school."

Why: This is when you want to ask for what reason. "Why isn't the the food warmed up yet?"

Whose: This is when you are asking if something belongs to someone. "Whose pencil does this belong to?"

Now, when you do the answers, look for the things that the relative pronouns are referring to. For example: "when" is talking about time. So, you look at answers that refer to a certain time. This works for #2. "The moment when..."

"Moment" is a unit of time, so it works for "when."

I'll go over #1 also.

"This is a restaurant..." OK, so we know that "restaurant is a place. So, that rules out when, which is time, who, which is people, which, which is different things, why, which is a reason, and whose, which is belonging to.

This works for "where." It is talking about where this restaurant is.
