question:
Passage: Sam Clayton is too good for his own good. A sermon by Rev. Daniels persuades him to help others in every way he can, including his wife Lu's good-for-nothing brother, Claude, who's been living with them rent-free for six months, and their neighbors the Butlers, who need a car for a vacation when theirs breaks down.
Sam is a department store manager whose boss, H.C. Borden, wants him to sell more and socialize less. Sam's a shoulder for clerk Shirley Mae to cry on when her romance breaks up. He also gives a $5,000 loan, without his wife's knowledge, to Mr. and Mrs. Adams, who need it to save a gas station they bought.
Lu is fed up with Sam's generosity, particularly when he ends up paying for the Butlers' car repairs, then letting the mechanic come over for home-cooked meals. The last straw for Lu comes when she learns they have a chance to put a down payment on a new house, except Sam has lent their nest egg to the Adamses.
Sam is unhappy, too. He's annoyed with the Butlers, who have crashed his car and can't pay to fix it. He also wants Claude to move out. Shirley Mae's troubles come to his door after she takes too many pills. Sam even gets robbed, and the bank refuses to make him a loan.
He is at his wit's end when the Adamses surprise him with a check for $6,000. They also give Claude a job, and Shirley Mae suddenly thinks she and Claude could have a future together. Sam and Lu feel better about life, particularly when Borden surprises him with a promotion at work.
Question: Who is given a promotion at work?
answer:
Sam Clayton.

Passage: Sometime after 4 p.m. on December 6, 1989, Marc Lepine arrived at the building housing the Ecole Polytechnique, an engineering school affiliated with the Universite de Montreal, armed with a semi-automatic rifle and a hunting knife. Lepine purchased a rifle on November 21, 1989, in a Checkmate Sports store in Montreal. He had told the clerk that he was going to use it to hunt small game. Lepine had been in and around the Ecole Polytechnique building at least seven times in the weeks leading up to December 6.
Lepine first sat in the office of the registrar on the second floor for a while. While there, he was seen rummaging through a plastic bag. He did not speak to anyone, even when a staff member asked if she could help him. Lepine left the office and was subsequently seen in other parts of the building before entering a second-floor mechanical engineering class of about sixty students at about 5:10 p.m. After approaching the student giving a presentation, he asked everyone to stop everything and ordered the women and men to opposite sides of the classroom. No one moved at first, believing it to be a joke until he fired a shot into the ceiling.Lepine then separated the nine women from the approximately fifty men and ordered the men to leave. He asked the remaining women whether they knew why they were there, and when one student replied "no," he answered: "I am fighting feminism." One of the students, Nathalie Provost, said, "Look, we are just women studying engineering, not necessarily feminists ready to march on the streets to shout we are against men, just students intent on leading a normal life." Lepine responded, "You're women, you're going to be engineers. You're all a bunch of feminists. I hate feminists." He then opened fire on the students from left to right, killing six, and wounding three others, including Provost. Before leaving the room, he wrote the word shit twice on a student project.Lepine continued into the second-floor corridor and wounded three students before entering another room where he twice attempted to shoot a female student. When his weapon failed to fire, he entered the emergency staircase where he was seen reloading his gun. He returned to the room he had just left, but the students had locked the door; Lepine failed to unlock it with three shots fired into the door. Moving along the corridor, he shot at others, wounding one, before moving towards the financial services office where he shot and killed a woman through the window of the door she had just locked.
Question: What is the first name of the person who sat in the office of the registrar on the second floor for a while?
answer:
Marc.

question:
Passage: Arthur Harris is the grumpy husband of Marion, who is terminally ill yet continues to participate with enthusiasm at her local seniors' choir, The OAP'Z. The choirmaster is a young teacher, Elizabeth who is preparing the choir to enter a local musical choir competition called "Shadow Song". Arthur is also estranged from his son, James. Marion's health deteriorates over time until one night when she dies in her sleep. Arthur initially takes this loss severely and cuts himself from his family and the choir. Eventually he agrees to take Marion's place in the choir. The transition proves to be a challenge for Arthur thanks to the unconventional songbook that includes racier songs such as Salt-N-Pepa's "Let's Talk About Sex" and Motorhead's "Ace of Spades". However he grows to enjoy spending time in the choir.
On the eve of the competition, Arthur has an argument with James in a failed attempt to rebuild their relationship and pulls out of the choir. The choir participates in the competition without Arthur. He arrives later but before he can perform with the choir, they are eliminated from the competition by the judges. The choir are on their way to return home in defeat when Arthur stops the bus and storms the musical competition's stage shortly joined by the rest of the choir. They perform again with Arthur singing a solo of "Lullabye (Goodnight, My Angel)". The choir finishes in third place and returns home triumphant. Arthur and his son, James (who watched him perform in the competition) reconnect on the journey home with James leaving an answering phone message confirming this later.
Question: Who is the estranged son's mother's choir teacher?
answer:
Elizabeth.
