How does Bram Stoker use Mina to defy Victorian era roles for females?

I inferred you are referring to the novel "Dracula" written by Bram Stoker.

Explanation:

Mina is described by Bram in the novel (page 306) as “one of God’s women, fashioned by His own hand to show us men and other women that there is a heaven where we can enter, and that its light can be here on earth. So true, so sweet, so noble, so little an egoist…”

Also. note that the Victorian era's roles for females were that a woman should marry and take part in their husbands' interests and business. Abd that before marriage, they would learn housewife skills such as weaving, cooking, washing, etc.

what are the following?
