After a recent spate of home improvements, four couples were having a dinner party to discuss the additions to their houses. Alan had not recently had a new bathroom. Kara had not yet done her kitchen, but perhaps would update it next. Brian, who is married to Maud, had not had new windows. Laura delighted in showing photographs of her new conservatory. Neither Charles nor David had a new kitchen. Julie had not had new windows. Alan, who also had not had windows, is not married to Laura and Charles is not married to Kara. Who is married to whom and what work had they recently undertaken, assuming that each couple had one improvement and no two couples had the same improvement.
