The effect of these words or first the meaning is that the author, Sojourner Truth an ex slave is obliged to those who listened to her speech and is concluding her speech and has stated that while white women may be oppressed too their oppression is still not as much as black women have suffered with the added oppression of slavery. She also states that she can work just as hard as a man so deserves to have equal rights.
That way you know what kind of audience your writing for you can use different words with a lot more complexity. its completely different writing for kindergarteners and writing a paper for a college seminar.
Hope this answered your question.
The exposition is the plot element that will provide background information, introduces main characters, and always establishes conflict.
