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 Input:
Passage: In mid-2011, Oklahoma had a civilian labor force of 1.7 million and non-farm employment fluctuated around 1.5 million. The government sector provides the most jobs, with 339,300 in 2011, followed by the transportation and utilities sector, providing 279,500 jobs, and the sectors of education, business, and manufacturing, providing 207,800, 177,400, and 132,700 jobs, respectively. Among the state's largest industries, the aerospace sector generates $11 billion annually.Tulsa is home to the largest airline maintenance base in the world, which serves as the global maintenance and engineering headquarters for American Airlines. In total, aerospace accounts for more than 10 percent of Oklahoma's industrial output, and it is one of the top 10 states in aerospace engine manufacturing. Because of its position in the center of the United States, Oklahoma is also among the top states for logistic centers, and a major contributor to weather-related research.The state is the top manufacturer of tires in North America and contains one of the fastest-growing biotechnology industries in the nation. In 2005, international exports from Oklahoma's manufacturing industry totaled $4.3 billion, accounting for 3.6 percent of its economic impact. Tire manufacturing, meat processing, oil and gas equipment manufacturing, and air conditioner manufacturing are the state's largest manufacturing industries.

Ex Output:
What state has the largest airline maintenance base in the world?

Passage: Beginning on December 11, 1945, Stafford hosted the Tuesday and Thursday broadcasts of NBC musical variety radio program The Chesterfield Supper Club. On April 5, 1946, the entire cast, including Stafford and Perry Como, participated in the first commercial radio broadcast from an airplane. The initial plan was to use the stand-held microphones used in studios but when these proved to be problematic, the cast switched to hand-held microphones, which because of the plane's cabin pressure became difficult to hold. Three flights were made that day; a rehearsal in the afternoon, then two in the evening—one for the initial 6:00 pm broadcast and another at 10:00 pm for the West Coast broadcast.Stafford moved from New York to California in November 1946, continuing to host Chesterfield Supper Club from Hollywood. In 1948, she restricted her appearances on the show to Tuesdays, and Peggy Lee hosted the Thursday broadcasts. Stafford left the show when it was expanded to 30 minutes, making her final appearance on September 2, 1949. She returned to the program in 1954; it ended its run on NBC Radio the following year. During her time with Chesterfield Supper Club, Stafford revisited some of the folk music she had enjoyed as a child. Weston, her conductor on the programme, suggested using some of the folk music for the show. With her renewed interest in folk tunes came an interest in folklore; Stafford established a contest to award a prize to the best collection of American folklore submitted by a college student. The annual Jo Stafford Prize for American Folklore was handled by the American Folklore Society, with the first prize of $250 awarded in 1949.

Ex Output:
What was the name of the person that conducted the Chesterfield Supper Club?

Passage: The ice must be cut through, broken up, or melted.  Tools can be directly pushed into snow and firn (snow that is compressed, but not yet turned to ice, which typically happens at a depth of 60 metres (200 ft) to 120 metres (390 ft)); this method is not effective in ice, but it is perfectly adequate for obtaining samples from the uppermost layers.  For ice, two options are percussion drilling and rotary drilling.  Percussion drilling uses a sharp tool such as a chisel, which strikes the ice to fracture and fragment it.  More common are rotary cutting tools, which have a rotating blade or set of blades at the bottom of the borehole to cut away the ice.  For small tools the rotation can be provided by hand, using a T-handle or a carpenter's brace.  Some tools can also be set up to make use of ordinary household power drills, or they may include a motor to drive the rotation.  If the torque is supplied from the surface, then the entire drill string must be rigid so that it can be rotated; but it is also possible to place a motor just above the bottom of the drill string, and have it supply power directly to the drill bit.If the ice is to be melted instead of cut, then heat must be generated.  An electrical heater built into the drill string can heat the ice directly, or it can heat the material it is embedded in, which in turn heats the ice.  Heat can also be sent down the drill string; hot water or steam pumped down from the surface can be used to heat a metal drillhead, or the water or steam can be allowed to emerge from the drillhead and melt the ice directly.  In at least one case a drilling project experimented with heating the drillhead on the surface, and then lowering it into the hole.Many ice drilling locations are very difficult to access, and drills must be designed so that they can be transported to the drill site.  The equipment should be as light and portable as possible.  It is helpful if the equipment can be broken down so that the individual components can be carried separately, thus reducing the burden for hand-carrying, if required.  Fuel, for steam or hot water drills, or for a generator to provide power, must also be transported, and this weight has to be taken into account as well.

Ex Output:

What object's weight has to be taken into account as well?
