anonymous · Answer

'Call-and-response'
These songs helped the slaves synchronize group tasks and made 
the work of difficult labour easier.
Most slaves couldn't write or read, so that one isn't right either.
If they passed it down to younger people it could easily be forgotten, doesn't seem to work.

I think that the correct answer is :  combining them with stories from the bible.
