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: In 1916, childhood best friends, Bob Wilson and Fred von Bergen, are test pilots working for an American company that builds bombers for the European allies. Since he is German-born and faces prejudice against his heritage, Fred loses his job and, unable to find other employment, decides to return to Germany to fight for his homeland. Although he has no special attachment to the German cause, Bob quits the aviation company and joins his friend in Germany. 
On their way to a German airfield, Red Cross nurse Alida Hoffman accidentally runs Bob and Fred off the road, Both men are immediately drawn to Alida, especially Bob although Fred is more shy. After Bob's first unsuccessful mission, Captain Wolters, the squadron's tyrannical leader, expresses his doubt about his loyalty but, desperate for pilots, gives him another chance. 
As the United States is drawn into the war, instead of sending him into a crucial air battle, Wolters arrests Bob. Fred, heartbroken that Alida has chosen Bob, quarrels with his friend, calling him a coward. Later, however, Fred allows his friend to escape from a firing squad and flee to the Allied lines. 
To prove his allegiance, Bob leads British bombers to the German base, while Fred is told by Wolters that he must shoot down Bob to prove his loyalty. Neither man is capable of killing the other, and, in the end, Fred sacrifices his life for Bob. After the war, Bob returns to Germany to marry Alida. The newly married couple then returns to the United States, and pay their respects to Fred's mother.
[EX A]: What is the first name of the man that is fired for being German-born?

[EX Q]: Passage: 4 is the fourth solo studio album by American singer Beyoncé. It was released on June 24, 2011 by Parkwood Entertainment and Columbia Records. Following a career hiatus that reignited her creativity, Beyoncé was inspired to create a record with a basis in traditional rhythm and blues that stood apart from contemporary popular music. Her collaborations with songwriters and record producers The-Dream, Tricky Stewart and Shea Taylor produced a mellower tone, developing diverse vocal styles and influences from funk, hip hop, and soul music.
Severing professional ties with father and manager Mathew Knowles, Beyoncé eschewed the music of her previous releases in favor of an intimate, personal album. 4's lyrics emphasize monogamy, female empowerment and self-reflection, a result of Beyoncé considering a maturer message to contend artistic credibility. In May 2011, Beyoncé submitted seventy-two songs to Columbia Records for consideration, twelve of which appeared on the standard edition.
4 was promoted in mid-2011 by television performances and festival appearances, such as Beyoncé's headlining Glastonbury Festival set. The album received generally positive reviews by music critics; several publications included it on their year-end lists. It was her fourth consecutive album to debut at number one on the US Billboard 200, and it also reached number one in Brazil, France, Ireland, South Korea, Spain, Switzerland and the United Kingdom. 4 spawned the international singles "Run the World (Girls)", "Best Thing I Never Had", "Party", "Love on Top" and "Countdown". "Love on Top" won the Grammy Award for Best Traditional R&B Performance at the 55th annual ceremony. As of December 2015, 4 has sold 1.5 million copies in the United States.

[EX Q]: Passage: Initially called "the bridge to nowhere", the Admiral Clarey Bridge was instrumental in Senator Daniel Inouye's "rebirth" of Ford Island and enabled over $500 million in development with special legislation (2814 US Code). It connected 45 families and 3,000 civilian workers to Kamehameha Highway, and visitor access enabled construction of the $50 million 16-acre (6.5 ha) Pacific Aviation Museum. Plans included 500 homes for Navy personnel, a child-development center and a Navy lodge.In planning the island's development, the Navy considered its operational needs and the island's historic value. However, the National Trust for Historic Preservation considered the Navy's communication style more directive rather than collaborative, restricting the NTHP's ability to share their concerns, and in 2001 designated Ford Island one of its 11 most-endangered sites. Although the Navy's plans included preserving important hangars, the control tower and seaplane ramps, they failed to protect the existing runway and 1920s housing and did not address preserving bullet holes on the seaplane ramps.  As hoped by the Trust, after the designation the Navy agreed to delay development of some of these items until an agreement could be reached.To accommodate additional facilities and housing, the Navy needed to upgrade the island's infrastructure. Its sewage system was upgraded with the 2001 installation of a 6,000-foot (1,800 m), 20-inch (510 mm) sewage main from the island to Pearl Harbor and improvements to the sewage-pumping station. Due to the bridge's unique design, which includes a floating section, it was impossible to use it to transit cable across the loch. In 2005, the Navy contracted drilling for primary and auxiliary conduits 20 feet (6.1 m) apart and parallel to the bridge from Halawa Landing to the Ford Island golf course. The contractor installed 5,045-foot (1,538 m)-long, 24-inch (610 mm)-thick carbon-steel high-magnetic casing conduits, and fiber-optic communications cables and 46kV power lines were fed through them.
In June 2013 the Navy planned to install 60,000 photovoltaic panels over 28 acres (11 ha) on the Ford Island runway, to comply with Congressional and Defense Department mandates to reduce dependence on fossil fuels and offset the cost of Hawaiian energy (the highest in the United States). This plan deviated from a 2009 proposal (using the panels to define the runway) in favor of panels producing twice the power. The Navy offered the Pacific Aviation Museum Pearl Harbor $250,000 toward renovation of the control tower's elevator in exchange for its support of the plan. The museum declined, organizing an internet campaign opposing the plan based on the runway's historic significance and highlighting Ford Island's role in the attack on Pearl Harbor and Amelia Earhart's visit. In response, the Navy decided to install the panels on existing structures around Pearl Harbor.
[EX A]:
What did the Navy need to do before they could build 500 homes on Ford Island?
