B was one of the answers that I crossed out first because of "real estate," I thought that it was too narrow and no where did tangible-object theorist mention real estate. Could anyone explain this to me?

Thanks!

Have to say I have finally understood the diagram but can't seem to understand the questions. Could anyone help me figure them out? Thanks!

During the actual LSAT I managed to only get two right, weeks later, same nightmare...It doesn't seem like there's a fantastic diagram to be drawn here or even that many inferences to make. I would love to see someone's diagram to try to make sense out of the questions. Thank you!
