[EX 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 first name of the person who sat in the office of the registrar on the second floor for a while?
[EX A]: Marc.

[EX Q]: Passage: Robert and Cathy Wilson (Robert Donat and Deborah Kerr) are a timid married couple in 1940 London. He is a bookkeeper, she a bored housewife. However, their tedium-filled lives are drastically changed by the war. He enlists in the Royal Navy, while she (against his wishes) joins the Wrens. During the three years the couple are apart, they are transformed, each becoming much more self-confident.
Cathy's assertive new friend, Dizzy Clayton, helps her break out of her shell. She begins going out with Dizzy's cousin, naval architect Richard, who falls in love with her. However, she remains faithful (if unenthusiastically) to her husband.
Meanwhile, Robert toughens up on sea duty and in time becomes a petty officer. His hands are badly burned when his ship is sunk, but he stoically rows in the lifeboat for five days without complaint. He recuperates in a hospital, tended by Elena, a beautiful nurse. On the last night of his stay, he asks her out to dinner. He is attracted to her, but she informs him that she lost her beloved husband only six months earlier, kisses him, and leaves.
Robert and Cathy both receive ten-day leaves, but each dreads being reunited with the dowdy spouse each remembers and being forced back into the dreary life they shared. 
Question: What is the first name of the cousin of the person who falls in love with the bored housewife?
[EX A]: Dizzy.

[EX Q]: Passage: The Navajo were an Athabaskan people who migrated from the north into the Colorado River basin around 1025 A.D. They soon established themselves as the dominant Native American tribe in the Colorado River basin, and their territory stretched over parts of present-day Arizona, New Mexico, Utah and Colorado – in the original homelands of the Puebloans. In fact, the Navajo acquired agricultural skills from the Puebloans before the collapse of the Pueblo civilization in the 14th century. A profusion of other tribes have made a continued, lasting presence along the Colorado River. The Mohave have lived along the rich bottomlands of the lower Colorado below Black Canyon since 1200 A.D. They were fishermen – navigating the river on rafts made of reeds to catch Gila trout and Colorado pikeminnow – and farmers, relying on the annual floods of the river rather than irrigation to water their crops. Ute peoples have inhabited the northern Colorado River basin, mainly in present-day Colorado, Wyoming and Utah, for at least 2,000 years, but did not become well established in the Four Corners area until 1500 A.D. The Apache, Cocopah, Halchidhoma, Havasupai, Hualapai, Maricopa, Pima, and Quechan are among many other groups that live along or had territories bordering on the Colorado River and its tributaries.Beginning in the 17th century, contact with Europeans brought significant changes to the lifestyles of Native Americans in the Colorado River basin. Missionaries sought to convert indigenous peoples to Christianity – an effort sometimes successful, such as in Father Eusebio Francisco Kino's 1694 encounter with the "docile Pimas of the Gila Valley [who] readily accepted Kino and his Christian teachings". From 1694 to 1702 Kino would explore the Gila and Colorado Rivers to determine if California was an island or peninsula. The Spanish introduced sheep and goats to the Navajo, who came to rely heavily on them for meat, milk and wool. By the mid-16th century, the Utes, having acquired horses from the Spanish, introduced them to the Colorado River basin. The use of horses spread through the basin via trade between the various tribes and greatly facilitated hunting, communications and travel for indigenous peoples. More warlike groups such as the Utes and Navajos often used horses to their advantage in raids against tribes that were slower to adopt them, such as the Goshutes and Southern Paiutes. 
Question: What did the Navajo rely heavily on for meat, milk and wool?
[EX A]:
sheep.
