Passage: A NASA spacecraft lands on an unknown planet and begins to take rock and soil samples. Four aliens discover it and are sucked into the craft through its vacuum tube, after which it makes its way back to Earth. The aliens are able to escape from a government base by using their powers (with which they can destroy or heal anything they touch). During the escape, the youngest one hides in a passing van, occupied by a boy named Eric Cruise who uses a wheelchair, his older brother, Michael, and their single mother, Janet, who are moving to California from Illinois.
Shortly after the Cruise family arrives at their new home, Eric becomes suspicious of the alien's presence. The next morning, he finds that the creature has trashed most of the house and learns its identity, but is blamed alongside his brother by their mother for what has happened. After seeing the creature again, Eric tries to catch up to him, but ends up sliding down a hill and falls into a lake, where he nearly drowns, but is rescued by the alien. Eric is not believed at all when he tries to tell his family about the creature's actions.
Later that night, he sets a trap with the help of his new friend, Debbie, who had also seen the alien. The two trap him inside a vacuum cleaner, which malfunctions and causes the entire neighborhood to suffer a power surge. After the alien is released, Michael now believes Eric, but it leaves before Janet can be convinced. Eric's behavior towards the alien changes after he fixes all of the damage he caused to the house, and leaves behind several newspaper clippings which Eric believes are an attempt to communicate.
Question: Who fixes the damage to the house?

Ex Output:
the alien.

Passage: Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television judge. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson under her birth name in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations and she subsequently began working with producers Glen Ballard, Dr. Luke, and Max Martin. After adopting the stage name Katy Perry and being dropped by The Island Def Jam Music Group and Columbia Records, she signed a recording contract with Capitol Records in April 2007.
Perry rose to fame in 2008 with the release of her second album, a pop rock record titled One of the Boys, and its singles "I Kissed a Girl" and "Hot n Cold". The former track also sparked controversy for its sapphic themes. Her third album, Teenage Dream (2010), ventured into disco, and was her first album to top the U.S. Billboard 200. It topped the U.S. Billboard Hot 100 with the singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)", while "The One That Got Away" reached number three on the chart. The album became the first by a female artist to produce five number-one songs in the U.S., and the second overall after Michael Jackson's album Bad. In March 2012, she re-issued the album as Teenage Dream: The Complete Confection, which produced the songs "Part of Me" and "Wide Awake". Her fourth album, Prism (2013), was her second to peak atop the U.S. charts. It is influenced by pop and dance, and she became the first artist with multiple videos to reach one billion views on Vevo with the videos for its songs "Roar" and "Dark Horse". Her fifth album, Witness (2017), delved into electropop and became her third album to reach number one in the U.S. "Chained to the Rhythm" was the album's most successful single, breaking Spotify's record at the time for most first-day streams for a song by a female artist.
Perry has received various awards, including four Guinness World Records, five American Music Awards, a Brit Award, and a Juno Award, and has been included in the annual Forbes lists of highest-earning women in music from 20112018. Her estimated net worth as of 2016 is $125 million. She is one of the best-selling music artists of all time, having sold more than 100 million records globally throughout her career. In film, she released an autobiographical documentary titled Katy Perry: Part of Me in 2012, and voiced Smurfette in the 2011 film The Smurfs and its sequel in 2013. Perry also began serving as a judge on American Idol in 2018.
Question: What is the better-known last name of the person who signed a recording contract with Capitol Records in April 2007?

Ex Output:
Perry.

Passage: Set 19 years after the events of the first film, the movie deals with unresolved conflict and family strain, and also has elements of a coming of age story.

Despite his obvious affiliation, Ross insists that he is part of no social cliques, which is stressed even further when he states that despite a lifelong abstinence from drugs, alcohol, and sex; he is not Straight Edge either.
Upon having his heart broken by his first girlfriend, Ross attempts to drown his sorrows, as well as his lifelong espousal that romantic love is trivial, with the aide of beer and liquor. In an attempt to further help him take his mind off of things, he also begrudgingly goes on a road trip to a punk rock concert with his only friend, Crash, as well as Crash's friend Penny. Ross has a low opinion of punks, despite his association with them, as Crash and Penny are punk rockers, as was his father.
Question: What is the name of the friend of Heroin Bob's son?

Ex Output:
Crash.
