Which best describes how "Aintl a Woman?" relates to the time period in which Truth lived?

Truth was trying to persuade people that women, black or white, should be treated as equal to men. They should have rights just like men. The tone in the beginning is of despair and sadness, with examples about working in the field and having most of her children sold into slavery. In that time period, women were not allowed to do much. Especially black people in general.
