"A servant to servants" is a Robert Frost's poem. It is the story of a woman who suffers from a mental illness and is tired of her daily routine. She finds it interesting to meet new people and to speak about her life. In this poem, the camper is an stranger but she is also friend, someone to share the burden of her illness and her daily life in a rural area. The stranger is a new life to her. That is the reason why it is so important to talk about her personal issues.
Answer: having second thoughts about her new job
Explanation:
Wavering means to be doubtful, unsure or uncertain about a particular thing. Someone who wavers is said to falter as the person is faced with an indecision.
When the narrator says "I was wavering in my secret soul", she means that she was having second thoughts about her new job.
Therefore, the answer is option D.
