Final answer:
The provided reference material does not specify who in Moody's family faced deadly retribution for her sit-ins. A broader look at the Civil Rights Movement reveals that violence against activists was common during that era.
Step-by-step explanation:
The individual in Moody's family who was almost killed in retribution for her sit-ins is not explicitly mentioned within the provided reference material. However, the sit-ins mentioned are reflective of the Civil Rights Movement where many African Americans were met with violence or threats of violence due to their actions to end racial segregation and discrimination.
The passage given discusses other incidents, such as Emmett Till's murder and the Montgomery Bus Boycott, which exemplify the violent backlash civil rights activists faced.
