Final answer:
Jane attains her position at Thornfield Manor through her inheritance as the daughter of Withersteen, who founded the village of Cottonwoods. She also asserts her position through her strong will and determination to make decisions based on love.
Step-by-step explanation:
Jane attains her position at Thornfield Manor through her inheritance. Her father, who founded and maintained the village of Cottonwoods, left Jane as its beneficent land-lord. As the daughter of Withersteen, she has control over the land, the water, and the property within the village.
Jane's position at Thornfield Manor is also reinforced by her strong will, fighting courage, and her determination to live her life according to her own truth. Although she faces challenges and pressures from the Mormon community to marry a man of their choosing, she remains steadfast in her decision to marry based on love and not just for duty.
