Task: Question Answering
Input (English): Passage: A group of puppies are stolen from a pet store by two thieves. A St. Bernard puppy escapes and sneaks into the Newton family's home. The workaholic father, George Newton, doesn't want the responsibility of owning a dog, but his wife, Alice, and their children, Ryce, Ted, and Emily, convince him. They give him the name "Beethoven" when Emily plays a portion of Ludwig van Beethoven's Fifth Symphony on the piano and the dog barks along to it.
Beethoven grows into an extremely fat adult dog and helps the children overcome their problems: he helps Ryce talk to her crush, scares off bullies for Ted, and saves Emily's life when she falls into an irresponsible babysitter's swimming pool. George, jealous of the affection Beethoven receives, feels neglected as his family fawns over him. His antics ruin a barbecue he is hosting for Brad and Brie, rude, unpleasant venture capitalists looking to invest in and secretly swindle him out of his car freshener firm.
The Newtons take Beethoven to a veterinarian, Dr. Herman Varnick, for a routine medical examination and immunizations. They are unaware that he is involved in unethical and deadly animal experimentation. He speaks to George and tells him of a supposed mental instability among St. Bernards making them potentially dangerous to humans and advises him to watch Beethoven closely for any sign of viciousness. He actually requires large-skulled dogs such as St. Bernards for an ammunition test. 
Question: Who is the mother of the girl that plays the piano while the dog barks?
Output (English): Alice.
