Answer:
1. Making an inference from the details given in the text Douglas most likely has a job working in a boiler-room.
2. Due to the description of the instructions Susan has laid out for Douglas she seems to be a tidy person who values a clean home, and desires structure. In the second sentence it states, "Susan would have a fit if the boots made it so far as the fount door." From this statement we can tell that Susan likes a clean home.
3. The text makes it seem like Susan and Douglas have a strained relationship because she wants him to be, "presentable," for dinner so he needs to take a shower. I feel this way because it seems that Susan tells Douglas to be presentable and she has done it several times.
