B6 He  (NOT/HAVE) a wife and he lived in a very large house with a housekeeper. He himself was a very old man with white hair which grew over most of his face as well as on his head.

B11 "We were going to explore the house," Peter reminded them. He (EAT) a sandwich at the moment and was absolutely happy with the whole situation.
