Input: Article: The majority of contemporary people with dogs describe their pet as part of the family, although some ambivalence about the relationship is evident in the popular reconceptualization of the doghuman family as a pack. A dominance model of doghuman relationships has been promoted by some dog trainers, such as on the television program Dog Whisperer. However it has been disputed that "trying to achieve status" is characteristic of doghuman interactions. Pet dogs play an active role in family life; for example, a study of conversations in doghuman families showed how family members use the dog as a resource, talking to the dog, or talking through the dog, to mediate their interactions with each other.

Now answer this question: What TV show promotes a dominance model for the relationships people have with their dogs?

Output: Dog Whisperer

Input: Article: Fifty-year-old Baena, of Guatemalan origin, was employed by the family for 20 years and retired in January 2011. The pregnant Baena was working in the home while Shriver was pregnant with the youngest of the couple's four children. Baena's son with Schwarzenegger, Joseph, was born on October 2, 1997; Shriver gave birth to Christopher on September 27, 1997. Schwarzenegger says it took seven or eight years before he found out that he had fathered a child with his housekeeper. It wasn't until the boy "started looking like me, that's when I kind of got it. I put things together," the action star and former California governor, told 60 Minutes. Schwarzenegger has taken financial responsibility for the child "from the start and continued to provide support." KNX 1070 radio reported that in 2010 he bought a new four-bedroom house, with a pool, for Baena and their son in Bakersfield, about 112 miles (180 km) north of Los Angeles. Baena separated from her husband, Rogelio, in 1997, a few months after Joseph's birth, and filed for divorce in 2008. Baena's ex-husband says that the child's birth certificate was falsified and that he plans to sue Schwarzenegger for engaging in conspiracy to falsify a public document, a serious crime in California.

Now answer this question: Baena worked for the Schwarzenegger/Shriver family for how many years?

Output: 20

Input: Article: Time travel is the concept of moving backwards or forwards to different points in time, in a manner analogous to moving through space, and different from the normal "flow" of time to an earthbound observer. In this view, all points in time (including future times) "persist" in some way. Time travel has been a plot device in fiction since the 19th century. Traveling backwards in time has never been verified, presents many theoretic problems, and may be an impossibility. Any technological device, whether fictional or hypothetical, that is used to achieve time travel is known as a time machine.

Now answer this question: Traveling which direction in time has never been verified and presents many problems?

Output:
backwards
