[Q]: Passage: Sometime after 4 p.m. on December 6, 1989, Marc Lépine arrived at the building housing the École Polytechnique, an engineering school affiliated with the Université de Montréal, armed with a semi-automatic rifle and a hunting knife. Lépine 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. Lépine had been in and around the École Polytechnique building at least seven times in the weeks leading up to December 6.
Lépine 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. Lépine 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.Lépine 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." Lépine 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.Lépine 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; Lépine 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 last name of the person who did not speak to anyone when a staff member asked if they could help him?
[A]: Lépine.


[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.
