In paragraph 60 the narrator describes Vashti's room as contain[ing] nothing but being in touch with all that she cared for in the world. What does this description reveal about her?

Vashti was immensely connected with what she values in the world.

Explanation:

Note some of the things we are told that Vashti loves and cares for; food, music, clothing, hot bath, literature, communication with friends.

This describes what she values and cares for the most, as each had a dedicated button that turns them on.

So even though Vashti's room contained nothing, she made sure she was in touch with all that she cared for in the world such as her friends, food, music, clothing, hot bath, and literature.
