This is a relatively simple question. 4 opens the paragraph by giving us the reference of time and place. It talks about white liberty in colonies, and slavery in those colonies. 4 says "the slaves could never be muted". 5 comes as an additional informationfor 4, because 5 clearly says that "slave owners were obsessed over slave talk" and 1 says "talk was the most common way for enslaved men and women to subvert the rules of their bondage" ......2 further adds to the story by stating that "even in conditionsof extreme violence.... their words remained ubiquitous". Thus 4512 form a logical link, with 3 as the odd one out. The sequence may not strictly be 4512, but in all cases 3 is the odd one.
