question:
Passage: In Seattle, strait-laced Matt Leland falls in love with Casey Roberts, the new girl at their high school who's from Chicago. They begin a sexual relationship. His father disapproves of this and her parents try to stop them from continuing to see each other. She deliberately sets off the fire alarm at school, knowing that there is no fire there, and is subsequently suspended. She has an argument with her parents when they tell her they are sending her to a boarding school. She takes an overdose and her parents subsequently arrange to have her committed. Matt helps Casey escape from an acute psychiatric ward, and as they run away they both deal with her borderline personality disorder.
Casey is eccentric in nature. Her impulsiveness and extreme risk-taking attitude and behavior is attributed to her illness, in which she experiences severe highs and lows of emotion. Her frequent intense feelings, of passion towards Matt and of fear and destructiveness, dominate her persona. Throughout the relationship, Matt selflessly puts her needs before his. The severity of this increases as her mental state worsens. 
Question: What are the first names of the people that run away from the institute?
answer:
Matt.


question:
Passage: Spanky McFarland is the president of the "He-Man Woman Haters Club" with many school-aged boys from around the neighborhood as members. Alfalfa Switzer, Spanky's best friend, has been chosen to be the driver for the club's prize-winning go-kart, "The Blur", in the upcoming Soap Box Derby go-kart race. However, Alfalfa is nowhere to be found.
The boys go to find Alfalfa and discover him in the company of his sweetheart Darla, with whom he is forbidden to be in love because she is a girl, which goes against club rules. Alfalfa invites Darla on a picnic, and to prove his devotion to her, he agrees to have the picnic inside the clubhouse. Unbeknownst to Alfalfa, his fellow club members find out about his plans.
At the picnic, Alfalfa and Darla think they are alone, but the other club members secretly pull several silly pranks to sabotage their romantic date (whoopee cushion, cat litter in sandwiches, etc.). When they finally reveal themselves and demand to come inside the clubhouse, Alfalfa frantically tries to convince Darla to hide in the closet, which leads her to mistakenly believe that Alfalfa feels ashamed of her. In the frenzy, a candle flame gets out of control, ultimately causing the clubhouse to burn down.
Darla breaks up with Alfalfa and turns her attentions towards Waldo, the new kid in town whose father is an oil tycoon. Because Alfalfa burned down the clubhouse and also fraternized with a girl, he is assigned by Stymie to guard the go-kart until the day of the race. 
Question: Who thinks that the go-kart driver is ashamed of her?
answer:
Darla.


question:
Passage: At the outbreak of the First World War, Holst tried to enlist but was rejected as unfit for military service. He felt frustrated that he could not contribute to the war effort. His wife became a volunteer ambulance driver; Vaughan Williams went on active service to France as did Holst's brother Emil; Holst's friends the composers George Butterworth and Cecil Coles were killed in battle. He continued to teach and compose; he worked on The Planets and prepared his chamber opera Savitri for performance. It was first given in December 1916 by students of the London School of Opera at the Wellington Hall in St John's Wood. It attracted no attention at the time from the main newspapers, though when professionally staged five years later it was greeted as "a perfect little masterpiece." In 1917 he wrote The Hymn of Jesus for chorus and orchestra, a work which remained unperformed until after the war.In 1918, as the war neared its end, Holst finally had the prospect of a job that offered him the chance to serve. The music section of the YMCA's education department needed volunteers to work with British troops stationed in Europe awaiting demobilisation. Morley College and St Paul's Girls' School offered him a year's leave of absence, but there remained one obstacle: the YMCA felt that his surname looked too German to be acceptable in such a role. He formally changed "von Holst" to "Holst" by deed poll in September 1918. He was appointed as the YMCA's musical organiser for the Near East, based in Salonica. 
Question: Who changed their surname?
answer:

Holst.
