[EX Q]: 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 A]: the alien.

[EX Q]: Passage: At a London music hall theatre, Richard Hannay is watching a demonstration of the superlative powers of recall of "Mr. Memory" (Wylie Watson) when shots are fired. In the ensuing panic, Hannay finds himself holding a seemingly frightened Annabella Smith, who talks him into taking her back to his flat. There, she tells him that she is a spy, being chased by assassins, and that she has uncovered a plot to steal vital British military information, masterminded by a man with the top joint missing from one of his fingers. She mentions the "39 Steps", but does not explain its meaning.
Later that night Smith, fatally stabbed, bursts into Hannay's bedroom and warns him to flee. He finds a map of the Scottish Highlands clutched in her hand, showing the area around Killin, with a house or farm named "Alt-na-Shellach" circled. He sneaks out of his flat disguised as a milkman to avoid the assassins waiting outside. He then boards the Flying Scotsman express train to Scotland. He learns from a newspaper article (read by a pair of women's undergarment salesmen) that he is the target of a nationwide manhunt for Smith's murder. When he sees the police searching the train, he enters a compartment and kisses the sole occupant, Pamela, in a desperate attempt to hide his face and escape detection. She frees herself from his unwanted embrace and alerts the policemen, who stop the train on the Forth Bridge. Hannay then escapes, hiding behind the bridge's truss.
Question: What is the full name of the person that the police are searching the train for?
[EX A]: Richard Hannay.

[EX Q]: Passage: El Mariachi is recruited by CIA agent Sheldon Jeffrey Sands to kill General Emiliano Marquez, a corrupt Mexican Army officer who has been hired by Mexican drug lord Armando Barillo to assassinate the President of Mexico and overthrow the government. Many years before, El Mariachi and his wife Carolina confronted Marquez in a shootout and wounded the general; in retaliation, Marquez took the lives of Carolina and their daughter in an ambush. In addition to El Mariachi, Sands persuades former FBI agent Jorge Ramirez to come out of retirement and kill Barillo, who had murdered his partner Archuleta in the past. Furthermore, AFN operative Ajedrez is assigned by Sands to tail Barillo.
While monitoring Barillo's activities, Ramirez meets Billy Chambers, an American fugitive who has been living under the protection of Barillo, but can no longer stomach the horrible tasks he's been forced to carry out for him. Ramirez convinces Chambers he will provide him protection in exchange for getting closer to Barillo by tagging Chambers' pet chihuahua with a hidden microphone, and Chambers agrees to complete the deal by surrendering to U.S. authorities once Barillo has been taken down. Sands' assistant, Cucuy, originally hired to keep an eye on El Mariachi, instead tranquilizes El Mariachi and turns him over to Barillo, also offering to reveal the details of Sands's plan. Cucuy, however, is promptly killed by Chambers while El Mariachi escapes from captivity and calls his friends Lorenzo and Fideo to assist him in his mission.
Question: What is the last name of the person who hires someone to kill the corrupt Mexican army officer?
[EX A]:
Sands.
