Question: Who played the girlfriend of Alex P. Keaton's actor on Family Ties in Back to the Future?

Knowledge 1: Alex P. Keaton
Alex P. Keaton is a fictional character on the United States television sitcom Family Ties, which aired on NBC for seven seasons, from 1982 to 1989. Family Ties reflected the move in the United States away from the cultural liberalism of the 1960s and 1970s to the conservatism of the 1980s. This was particularly expressed through the relationship between Young Republican Alex (Michael J. Fox) and his hippie parents, Steven (Michael Gross) and Elyse Keaton (Meredith Baxter). President of the United States Ronald Reagan once stated that Family Ties was his favorite television show. [SEP] Knowledge 2: Back to the Future
Following Stoltz's departure, Fox's schedule during weekdays consisted of filming Family Ties during the day, and Back to the Future from 6:30 pm to 2:30 am. He averaged five hours of sleep each night. During Fridays, he shot from 10 pm to 6 or 7 am, and then moved on to film exterior scenes throughout the weekend, as only then was he available during daytime hours. Fox found it exhausting, but "it was my dream to be in the film and television business, although I didn't know I'd be in them simultaneously. It was just this weird ride and I got on." Zemeckis concurred, dubbing Back to the Future "the film that would not wrap". He recalled that because they shot night after night, he was always "half asleep" and the "fattest, most out-of-shape and sick I ever was".
