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.

Example Input: Passage: Motivated by a variety of reasons from college tuition support, to a sense of purpose, best friends Dominic and Cole join the Army National Guard after graduating from their rural high school.  After persuading several of their friends to join them, the young men are sent to Afghanistan as part of the 107th Engineer Battalion, 168th Engineer Brigade, where they are tasked with searching for roadside bombs in order to keep roads safe for other troops.  By the time their deployment ends, they are no longer the carefree group of friends they were before enlisting; repeated bombs blasts around their convoys have led to TBI symptoms, and they have become increasingly disillusioned about their mission.
Coming home is no relief as they are now confronted with the silent war wounds of PTSD and TBI. The soldiers struggle with reintegration with society and some miss the simplicity in life they had while in Afghanistan. The latter half of the documentary focuses on their struggles on the home front and how each of them, and their families try to return to normal life.
Example Output: Who is sent to Afghanistan?

Example Input: Passage: In December 1775, Cletus Moyer is a free black Northerner in colonial America, working with a pre-Underground Railroad network to help slaves escape captivity. In the days just prior to Christmas, a group of bounty hunters led by Hattie Carraway captures Moyer near the Parker plantation in Spotsylvania County, Virginia. Because of his capture, dozens of slaves who have already left their plantations in escape attempts are in danger of being captured as well. Moyer implores two slaves from the nearby Reynolds plantation to take his place: Kunta Kinte, a Mandinka in his mid-twenties who was captured in what is now the Gambia, and Fiddler, an elderly man who was born into slavery. Kunta is eager to help (and to escape himself), but Fiddler is unwilling, fearful of the consequences if they are caught.
After an unsuccessful slave revolt elsewhere in the colony, Moyer and two slaves are hanged by Carraway's men on Christmas Eve, prompting Fiddler to set aside his fear and help Kunta lead the runaway slaves to freedom. Although the pair successfully leads the runaways that night to their next stop on the escape route (a boat waiting at the river) there is only room for one of them, and since neither one wants to go without the other, they both decide to stay.  That choice forces them to return to the Parker plantation and manufacture an excuse for their temporary absence. Nevertheless, Kunta and Fiddler are left with the satisfaction of knowing that they helped to give a group of fellow slaves the best Christmas gift of all: freedom.
Example Output: What's the first name of the person who dies the day before Christmas?

Example Input: Passage: San Francisco (SF; , Spanish: [sam fɾanˈsisko]; Spanish for 'Saint Francis'), officially the City and County of San Francisco, is a city in, and the cultural, commercial, and financial center of, Northern California. San Francisco is the 13th-most populous city in the United States, and the fourth-most populous in California, with 883,305 residents as of 2018. It covers an area of about 46.89 square miles (121.4 km2), mostly at the north end of the San Francisco Peninsula in the San Francisco Bay Area, making it the second-most densely populated large US city, and the fifth-most densely populated U.S. county, behind only four of the five New York City boroughs. San Francisco is also part of the fifth-most populous primary statistical area in the United States, the San Jose–San Francisco–Oakland, CA Combined Statistical Area (9.67 million residents).
As of 2017, it was the seventh-highest income county in the United States, with a per capita personal income of $119,868. As of 2015, San Francisco proper had a GDP of $154.2 billion, and a GDP per capita of $177,968. The San Francisco CSA was the country's third-largest urban economy as of 2017, with a GDP of $907 billion.  Of the 500+ primary statistical areas in the US, the San Francisco CSA had among the highest GDP per capita in 2017, at $93,938. San Francisco was ranked 14th in the world and third in the United States on the Global Financial Centres Index as of September 2018.San Francisco was founded on June 29, 1776, when colonists from Spain established Presidio of San Francisco at the Golden Gate and Mission San Francisco de Asís a few miles away, all named for St. Francis of Assisi. The California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856. San Francisco's status as the West Coast's largest city peaked between 1870 and 1900, when around 25% of California's population resided in the city proper.  After three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a major port of embarkation for service members shipping out to the Pacific Theater. It then became the birthplace of the United Nations in 1945. After the war, the confluence of returning servicemen, significant immigration, liberalizing attitudes, along with the rise of the "hippie" counterculture, the Sexual Revolution, the Peace Movement growing from opposition to United States involvement in the Vietnam War, and other factors led to the Summer of Love and the gay rights movement, cementing San Francisco as a center of liberal activism in the United States. Politically, the city votes strongly along liberal Democratic Party lines.
Example Output:
How much of San Francisco was destroyed by the 1906 earthquake and fire?
