(4)- Which is the best prediction about what might be included in the "Victory through Air Power!” section?
A)- Examples of the advances of black female mathematicians
B)- Concluding remarks about the inclusion of black women in scientific fields
C)- Scientific explanation of how airplanes work
D)- Background on the production of airplanes during World War II

D)- Background on the production of airplanes during World War II

Explanation:

Victory through Air Power seems to be related to the use of airplanes during wars to defeat the enemy.

It would therefore be logical that the section would talk about how countries could go about doing so and include details about the planes that would enable such ambitions. A background on the production of planes during a war such as WW2 would therefore be the most likely to be included here.

the purpose of the heading in the passage is to identify who is telling the story.

this excerpt is part of the book sugar changed the world (2010) written by marc aronson and marina budhos. as the book has been written by two people, the heading "marc" indicates that this specific excerpt is being narrated by aronson. in the fragment, marc describes his grandfather's story after hearing it from his cousin. however, there are other excerpts where budhos is the one that tells the story of her family.

aronson and budhos, who are husband and wife in real life, decided to write sugar changed the world when they found out how sugar, which had an important role in slavery and economy, changed their ancestors' lives.
