Task: Question Answering
Input (English): Passage: In 2007, David Moran, a Wall Street player, witnesses a man hit and run by a car. He responds to the situation and tries to resuscitate the victim. That evening, he reflects on his past to the summer of 1958, when he meets his first teenage crush Meg Loughlin. Meg and her disabled sister Susan have lost their parents in a car accident and because of this, they are sent to live with their reclusive aunt, Ruth Chandler, and her sons, Willie, Ralphie, and Donny (Graham Patrick Martin, Austin Williams and Benjamin Ross Kaplan).
Living next door to the Chandlers, David is aware of the charisma Ruth has, since she freely allows her sons and their neighborhood friends to her house, where she entertains them and offers them beer and cigarettes. Meanwhile, Ruth starves Meg, accuses her of being a whore and subjects her to misogynistic lectures, whilst her children listen. One day, David visits the Chandler residence, where he sees the Chandler sons tickling Meg. Ralphie inappropriately tickles Meg's breasts, prompting her to fend him off as she runs from the room. His brothers humiliate Susan and when Ralphie brings Ruth to the situation, Ruth reprimands her for forgiving Meg's actions. Ruth beats Susan's bare buttocks as the Chandler sons restrain a horrified Meg, who came back to the room to save Susan. Ruth then takes the ring that Meg wears around her neck, which belonged to her mother. 
Question: What are the first names of the people who humiliate Susan?
Output (English): Donny.
