Generate a question about the following movie plot: Alison Scott (Katherine Heigl) is a career-minded woman who has just been given an on-air role with E! and is living in the pool house with her sister Debbie's (Leslie Mann) family. Ben Stone (Seth Rogen) is laid-back and sardonic. He lives off funds received in compensation for an injury and sporadically works on a celebrity porn website with his roommates (Jay Baruchel, Jonah Hill, Jason Segel and Martin Starr), in between smoking marijuana or going off with them at theme parks such as Knott's Berry Farm. While celebrating her promotion, Alison meets Ben at a local nightclub. After a night of drinking, they end up having sex. Due to a misunderstanding, they don't use protection: Alison uses the phrase "Just do it already" to encourage Ben to put the condom on, but he misinterprets this to mean to dispense with using one. The following morning, they quickly learn over breakfast that they have little in common and go their separate ways, which leaves Ben visibly upset. Eight weeks later, Alison experiences morning sickness during an interview with James Franco and realizes she could be pregnant. She contacts Ben for the first time since their one-night stand to tell him. Although insensitive at first, Ben says he will be there to support Alison. While he is still unsure about being a parent, his father (Harold Ramis) is excited. Alison's mother (Joanna Kerns) tries to persuade her daughter to have an abortion, but Alison decides to keep the child. Later, Alison and Ben decide to give their relationship a chance. The couple's efforts include Ben making an awkward marriage proposal with an empty ring box, promising to get her one someday. Alison thinks it's too early to think about marriage, because she is more concerned with hiding the pregnancy from her bosses, believing that they will fire her if they ever found out. After a somewhat promising beginning, tensions surface in the relationship. Alison is increasingly worried about Ben's lack of responsibility and commitment, and has doubts about the longevity...
The answer to this question is:
Does Ben and Alison have a son or daughter?
