Answer:
A) To show the disparity between the number of women in the United States and the number who hold upper level jobs.
Step-by-step explanation:
Shirley Anita Chisholm (1924 – 2005) was an American politician, educator, and author.
Although much less context of the excerpt exists, but it is safe to establish that she being a woman and a politician wanted to show the disparity between the number of women in the USA and the number who held upper level jobs.
Option B and C are not correct, because she being a learned and able lady did not need to show any one that she had researched the topic thoroughly or showing that she understands the importance of supporting statement.
Option D is also incorrect, as no one can except such self-boasting from a such a woman.
