Input: Consider Input: 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 Beyoncé 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 Beyoncé's remix album with videography, Above and Beyoncé, and the platinum edition of I Am... Sasha Fierce.
Beyoncé 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. Beyoncé 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 thing—it'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 Fosse—very modern and very vintage. 
Question: What  videos were released to other media outlets on the same date and subsequently included on Beyoncé's remix album with videography?

Output: Single Ladies.


Input: Consider Input: Passage: Nannerl herself was an   apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activity—at the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present. 
Question: Who played the keyboard with striking virtuosity?

Output: Wolfgang.


Input: Consider Input: Passage: Wildlife photographer Pickett Smith is taking photographs of the local flora and fauna as he canoes through a swamp surrounding an island containing the affluent mansion estate of the wealthy and influential Crockett family. Also evident throughout the swamp are numerous indicators of pollution, which Pickett believes are connected to pesticide use on the island plantation. After Clint Crockett accidentally tips over Smith's canoe, he and his sister Karen escort Smith to the family mansion where he meets the entire Crockett family. The grouchy, wheelchair-bound patriarch Jason intends on spending the next day enjoying both the 4th of July and his own birthday celebrations uninterrupted. Due to the mutual dislike of the fauna around the mansion, Jason sends a man named Grover to spray pesticide in order to get rid of the frogs. Pickett later discovers Grover's corpse covered in snakebites in the swamp not far from the house. Despite this warning, Jason continues with his celebrations the next day.
Early next morning, Michael Martindale sets out to check on a possible downed telephone line. He accidentally shoots himself in the leg and is rendered immobile by strange white moss hanging down from the surrounding trees. Tarantulas descend from the branches and kill him. 
Back on the estate, Jason's sister, Iris Martindale sends her son, Kenneth into the greenhouse to collect flowers for a centerpiece. As he gathers the flowers, he fails to notice dozens of tokay geckos entering behind him. The geckos swarm over the stacked shelves, knocking over numerous jars of poisonous chemicals, and the resulting toxic gas asphyxiates him.
Seeing the danger posed by the animals, Pickett suggests that everyone should leave the island, but Jason is adamant that nothing will ruin his birthday. 
Question: How did Iris's son die?


Output: toxic gas asphyxiates him.
