PLEASE HELP ME! What bold step did a mathematician named Miriam Mann take at Langley to fight against racial discrimination?

A. She demanded that NACA hire Dorothy Vaughan.

B. She protested the fact that African American employees at Langley had to ride in the back of the bus.

C. She went to work in the all-white East Area Computing office.

D. She repeatedly removed a sign that indicated where all of the African American women had to eat in the cafeteria.

i think that the quotes in paragraph 11 contribute to the development of ideas because it provides a good reasoning of the central idea of the text.

its repetition emphasizing that the chain is his own. sorry if i am wrong.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
