Example Input: Passage: In December, Beyoncé along with a variety of other celebrities teamed up and produced a video campaign for "Demand A Plan", a bipartisan effort by a group of 950 US mayors and others designed to influence the federal government into rethinking its gun control laws, following the Sandy Hook Elementary School shooting. Beyoncé became an ambassador for the 2012 World Humanitarian Day campaign donating her song "I Was Here" and its music video, shot in the UN, to the campaign. In 2013, it was announced that Beyoncé would work with Salma Hayek and Frida Giannini on a Gucci "Chime for Change" campaign that aims to spread female empowerment. The campaign, which aired on February 28, was set to her new music. A concert for the cause took place on June 1, 2013 in London and included other acts like Ellie Goulding, Florence and the Machine, and Rita Ora. In advance of the concert, she appeared in a campaign video released on 15 May 2013, where she, along with Cameron Diaz, John Legend and Kylie Minogue, described inspiration from their mothers, while a number of other artists celebrated personal inspiration from other women, leading to a call for submission of photos of women of viewers' inspiration from which a selection was shown at the concert. Beyoncé said about her mother Tina Knowles that her gift was "finding the best qualities in every human being." With help of the crowdfunding platform Catapult, visitors of the concert could choose between several projects promoting education of women and girls. Beyoncé is also taking part in "Miss a Meal", a food-donation campaign, and supporting Goodwill charity through online charity auctions at Charitybuzz that support job creation throughout Europe and the U.S. Question: What song did Beyoncé donate to the 2012 World Humanitarian Day campaign?
Example Output: I Was Here

Example Input: Passage: Twins (1988), a comedy with Danny DeVito, also proved successful. Total Recall (1990) netted Schwarzenegger $10 million and 15% of the film's gross. A science fiction script, the film was based on the Philip K. Dick short story "We Can Remember It for You Wholesale". Kindergarten Cop (1990) reunited him with director Ivan Reitman, who directed him in Twins. Schwarzenegger had a brief foray into directing, first with a 1990 episode of the TV series Tales from the Crypt, entitled "The Switch", and then with the 1992 telemovie Christmas in Connecticut. He has not directed since. Question: What 1992 TV movie did Schwarzenegger direct?
Example Output: Christmas in Connecticut

Example Input: Passage: Special guest referees may be used from time to time; by virtue of their celebrity status, they are often scripted to dispense with the appearance of neutrality and use their influence to unfairly influence the outcome of the match for added dramatic impact. Face special referees will often fight back against hostile heel wrestlers, particularly if the special referee is either a wrestler themselves or a famous martial artist (such as Tito Ortiz in the main event at TNA's THard Justice in 2005). They also have the power to eject from ringside any of the heel wrestler's entourage/stable, who may otherwise interfere with the match. Question: What kind of referees are occasionally used?
Example Output:
Special guest referees may be used from time to time;
