In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[EX Q]: Passage: For his 1896 attempt to launch the balloon, Andree had many eager volunteers to choose from. He picked Nils Gustaf Ekholm, an experienced Arctic meteorological researcher and formerly his boss during an 18821883 geophysical expedition to Spitsbergen, and Nils Strindberg, a brilliant student who was doing original research in physics and chemistry. The main scientific purpose of the expedition was to map the area by means of aerial photography, and Strindberg was both a devoted amateur photographer and a skilled constructor of advanced cameras.This was a team with many useful scientific and technical skills, but lacking any particular physical prowess or training for survival under extreme conditions. All three men were indoor types, and only one, Strindberg, was young. Andree expected a sedentary voyage in a balloon basket, and strength and survival skills were far down on his list.Modern writers all agree that Andree's North Pole scheme was unrealistic. He relied on the winds blowing more or less in the direction he wanted to go, on being able to fine-tune his direction with the drag ropes, on the balloon being sealed tight enough to stay airborne for 30 days, and on no ice or snow sticking to the balloon to weigh it down.In the attempt of 1896, the wind immediately refuted his optimism by blowing steadily from the north, straight at the balloon hangar at Danes Island, until the expedition had to pack up, let the hydrogen out of the balloon, and go home. It is now known that northerly winds are to be expected at Danes Island; but in the late-19th century, information on Arctic airflow and precipitation existed only as contested academic hypotheses. Even Ekholm, an Arctic climate researcher, had no objection to Andree's theory of where the wind was likely to take them. The observational data simply did not exist.
[EX A]: What is the full name of the person who had no objection to Andree's theory of where the wind was likely to take them ?

[EX Q]: Passage: Joy Linnett and her stepsister Jackie miss a flight home to Ohio, but the attractive Joy, accustomed to getting her way with men, flirts with pilot Stevie Wilson until he agrees to personally fly the two young women.
At home, old beau Warren James comes calling and invites Jackie to a country club's dance. As soon as Joy emerges in a swimsuit, the smitten Warren not only neglects Jackie, he invites her sister to the dance.
A quarrel ensues between the women's parents. Jackie's dad is outraged by the way his daughter is treated, but Joy's mom says he's just miffed that her daughter is more popular than his.
Stevie calls out of the blue, giving Jackie an idea. She emulates her sister's behavior and wardrobe, persuading Stevie to accompany her to the dance. Once there, all the men get a look at the new Jackie and line up to dance with her, as sister Joy looks on, delighted. Now it is Warren who is neglected, so much so that he gets drunk and proposes marriage to both sisters. In the end, he comes to appreciate that Jackie is the one he really loves.
[EX A]: What is the full name of the person Warren invites to the dance?

[EX Q]: Passage: The music video for "Single Ladies" was shot immediately after that of "If I Were a Boy", but it received less attention during production than the "higher-gloss, higher-profile video" for "If I Were a Boy". Both videos were shot in black-and-white in New York City and were directed by Jake Nava, with whom Beyonce had worked on previous music videos including "Crazy in Love" and "Beautiful Liar". "Single Ladies" was choreographed by Frank Gatson Jr. and JaQuel Knight, and incorporates J-Setting choreography. The two music videos premiered on MTV's Total Request Live show on October 13, 2008 to reinforce the concept of conflicting personalities. The videos were released to other media outlets on the same date and subsequently included on Beyonce's remix album with videography, Above and Beyonce, and the platinum edition of I Am... Sasha Fierce.
Beyonce told Simon Vozick-Levinson of Entertainment Weekly that the inspiration for the video was a 1969 Bob Fosse routine entitled "Mexican Breakfast" seen on The Ed Sullivan Show, which featured Fosse's wife, Gwen Verdon, dancing with two other women. "Mexican Breakfast" had become an Internet viral sensation the previous summer after Unk's "Walk It Out" was dubbed over the original mix. Beyonce wanted to attempt a similar dance and eventually, the choreography of "Single Ladies" was liberally adapted from "Mexican Breakfast":
I saw a video on YouTube. [The dancers] had a plain background and it was shot on the crane; it was 360 degrees, they could move around. And I said, 'This is genius.' We kept a lot of the Fosse choreography and added the down-south thingit's called J-Setting, where one person does something and the next person follows. So it was a strange mixture ... It's like the most urban choreography, mixed with Fossevery modern and very vintage.
[EX A]:
What is the name of the person whose song was Single Ladies?
