In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Kel and Kath return from The Da Vinci Code European tour and begin frantic preparations for Christmas. During the two weeks leading up to Christmas Day Kim discovers that Brett is once again having an affair, this time with his boss Kelly. Brett stays at "The Buckingham Motel". Kim eventually asks him back, but he is still conducting the affair. Sharon meets a man, Marriat, online and they become engaged. She is heart broken to later learn that he does not actually exist, but is just a blog. Kath and Kel become backup dancers for Michael Bublé at Carols by Candlelight, Melbourne. Kath's affection for him results in Kel letting out his "green eyed monster". She tells him that he shouldn't bother going home as he wouldn't be welcome. Kel too goes to stay at "The Buckingham". Kath forgives Kel and he returns home for Christmas. Kath and Kel also receive strange messages from John Monk, the albino running Da Vinci Code tour, including one saying "44 Euros". John Monk visits their home. Kel thinks he has cracked the code and Monk is going to kill them, but he just wants to offer them a franchise. An epilogue shows Kath's first day as a tour guide on the Da Vinci Code 2 tour: G'day Leonardo.
Whose home does John Monk visit?
