In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Q: Passage: As Greeneville ascended to periscope depth, Waddle checked the sonar displays and the fire control station monitors, but reported later that he heard and saw nothing to suggest that the previously detected vessels in the area were now any closer to the submarine's position than had been reported before the submarine began the high speed maneuvers. Because the AVSDU was not working, Greeneville's executive officer, Lieutenant Commander Gerald K. Pfeifer, entered the sonar room and observed the contacts on the sonar screens.  Pfeifer then stood in the doorway between the sonar and control rooms, but did not communicate any updated sonar information to Waddle in the control room.  At 13:34, sonar gained a new contact, designated S-14.  Because Greeneville had not maintained a steady, slow course for a sufficient amount of time, the sonar data available to the Fire Control Technician of the Watch did not allow  accurate determination on Ehime Maru's range or course.  Also, due to time constraints placed by Waddle, the ship did not perform normal maneuvers which would be used to obtain accurate course and range information on the sonar contacts prior to proceeding to periscope depth.At 13:38, Greeneville reached periscope depth (about 60 feet (18 m) below the surface).  At this time, Ehime Maru was about 2,315 yards (2.117 km) or 1.14 nautical miles (2.1 km) away from the submarine and heading in her direction.  Although sonar data began to more accurately depict Ehime Maru's true range and bearing at this point, this was not evident to the sonar operators.  Lieutenant, Junior Grade Michael J. Coen, the officer of the deck, conducted an initial low  magnification periscope search of the area and sighted no nearby ships.  
Waddle then took the periscope before Coen could complete the normal high magnification search.  Since waves were washing over the periscope, Waddle ordered the submarine to go up another few feet to increase the distance the periscope can view.  Waddle then looked through the periscope at the area where he believed the reported surface contacts to be (possibly in error).  Although Ehime Maru was at this point heading toward Greeneville's location, Waddle failed to see the ship.  Regulations mandated that Waddle conduct a three-minute, 360-degree periscope scan before executing the emergency main ballast blow maneuver.  Waddle, however, aware that they were still behind schedule, conducted a short scan, searching primarily in the sector where he believed
the known contacts were located, noted that the haze was still present, and saw no ships in the vicinity.  At the end of his scan, Waddle announced to the control room crew, "I hold no visual contacts." Waddle later explained how he conducted his periscope search:. 
Question: What is the first name of the person who didn't finish the normal high magnification search before Waddle took the periscope?

A: Michael.

Q: Passage: At the court in Ferrara, a collection of ladies skilled in music inspired the composer Luzzasco Luzzaschi and caught the Duke's interest. This group, which led to the formation of the concerto delle donne, performed within the context of the Duke's musica secreta, a regular series of chamber music concerts performed for an exclusive audience. This preliminary group was originally made up of talented but amateur members of the court: the sisters Lucrezia and Isabella Bendidio, Leonora Sanvitale, and Vittoria Bentivoglio. They were joined by bass Giulio Cesare Brancaccio, who was specifically brought to the court in 1577 for his singing ability. The preliminary ensemble was active throughout the 1570s, and its membership solidified in 1577. Only later did professionals replace these original singers.
The Duke did not announce the creation of a professional, all-female ensemble; instead, the group infiltrated and gradually dominated the musica secreta, so that after the dismissal of Brancaccio for insubordination in 1583, no more male members of the musica secreta were hired. Even when Brancaccio was performing with the consort it was referred to as a ladies' ensemble, because women singing together was the most exciting aspect of the group. This new ensemble, the concerto delle donne, was created by Alfonso in part to amuse his young new wife, Margherita Gonzaga d'Este (she was only fourteen when they wed in 1579), and in part to help the Duke achieve his artistic goals for the court. According to Grana, a contemporary correspondent, "Signora Machiavella [Lucrezia], Signora Isabella, and Signora Vittoria have abandoned the field, having lost the backing of Luzzaschi". The first recorded performance by the professional ladies was on November 20, 1580; by carnival season in 1581, they were performing together regularly.This new "consort of ladies" was viewed as an extraordinary and novel phenomenon; most witnesses did not connect the second period of the concerto delle donne with the group of ladies who sang in the musica secreta. Today, however, the earlier group is viewed as a crucial part of the creation and development of the social and vocal genre of the concerto delle donne. 
Question: What were the first names of the two sisters in the original preliminary group?

A: Lucrezia.

Q: 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?

A:
Alice.
