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: Single father Bob Holcomb, a widower, is unhappy with the guitar-playing boy Kenny his daughter JoJo chooses as a husband-to-be. An executive with an oil company, Bob accepts a transfer to the firm's Stockholm branch and he takes JoJo along, hoping it will distract her.
Sweden turns out to be far more liberal sexually than the United States. Bob, having met an attractive interior designer, Karin, decides to take her away for a romantic weekend at a mountain resort.
JoJo, however, has accepted a similar offer from Erik, who is Bob's new assistant. Originally seen as a respectable suitor, Erik turns out to be a playboy and a cad. A girl thought to be his cousin, Marti, is actually a former girlfriend.
Kenny turns up and brings Marti along to the resort, where the three couples continue to awkwardly encounter one another. Kenny finally has his fill of Erik, knocking him out with his guitar. On a voyage home, the ship's captain performs a double wedding ceremony, that turns out to be invalid, due to a navigation error. So it needs to be done again.
Whose father does the interior designer begin seeing?
