How , I don’t know how can i do this home work

last one is the answer

we cant know we need to see to put any anwers

the answer is c.   the fact that the poet mentions what some people wear when they go to church to keep the sabbath shows that she knows about this tradition or custom. this demonstrates her authority because, when she decides the way she will worship, she knows what she is talking about and chooses an alternative to only going to church to keep the sabbath.
