E. acknowledge more fully the achievements of women in the computer science community

C. rebut the video’s premise about the steps required to make programming skills more widespread

Explanation:

Answer C

Correct. According to the passage, Margolis feels “unease” because the video fails to acknowledge that not everyone has access to certain “fundamental factors” required to learn programming.
