During the Freedom Summer campaign of 1964 in Mississippi,

Answer 1

It looks like your question was cut off — do you mean “what happened,” “what was its purpose,” or are you asking to choose among answer choices?

Brief summary you can use right away:
- Freedom Summer (Mississippi Summer Project) was a 1964 campaign organized mainly by SNCC and CORE to register Black Mississippians to vote and to set up Freedom Schools.
- Hundreds of volunteers (many white college students from the North, plus local Black activists) ran voter-registration drives, community centers, and Freedom Schools.
- The campaign met intense violent resistance: local authorities and white supremacists attacked workers, bombed churches and homes, and murdered civil-rights workers — most famously James Chaney, Andrew Goodman, and Michael Schwerner.
- The violence drew national attention, helped expose entrenched racism and official complicity, and helped build momentum for later federal action (notably the Voting Rights Act of 1965).
