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: The two main requirements of an anti-torque system are that it should prevent rotation of the sonde, and it should allow easy movement of the drill up and down the borehole.  Attempts have been made to design drills with counter-rotating components so that overall torque is minimized, but these have had limited success.  Five kinds of anti-torque systems have been devised for use with cable-suspended EM drills, though not all are in current use, and some drills have used a combination of more than one design.  The first drill to require an anti-torque system was used at Camp Century by CRREL in 1966; the drill incorporated a set of hinged friction blades that swung out from the sonde when the drill motor was started.  These were found to have very weak friction against the borehole wall, and were ineffective; the drill had to be controlled carefully to prevent twisting the cable.  No other drills have attempted to use this approach.For the next deployment of the drill leaf springs were installed, and this has proved to be a more durable design.  These are mounted vertically, with a curve outwards so that they are easily compressed by the borehole wall, and can slide up and down with the movement of the drill.  They pass easily through any areas of irregularity in the borehole, but the edges of the springs cut into the borehole wall and prevent rotation.  Leaf springs are very simple mechanically, with the additional benefit of being easy to adjust by changing the spacing between the end points.  They can be placed anywhere on the drill that does not rotate, so they do not add length to the sonde.  The shape is usually a fourth-order parabola, since this has been determined to provide the most even loading against the borehole wall.  Leaf springs have been found to be so effective that they can prevent rotation even in heavy drills running at full power.Skate antitorque systems have blades attached to vertical bars which are pushed against the borehole wall; the blades dig into the wall and provide the anti-torque.  Skates can be built with springs which allow them to keep the blades pressed against the wall in an irregular borehole, and to prevent problems in narrower parts of the borehole.  Although skates are a popular design for anti-torque and have been used with success, they have difficulty preventing rotation in firn and at boundaries between layers of different densities, and can cause problems when drilling with high torque.  When they fail, they act as reamers, removing chips from the wall which can fall to the drillbit and interfere with drilling.

Ex Output:
What acts as reamers when they fail?

Passage: Cleveland's position as a center of manufacturing established it as a hotbed of union activity early in its history. While other parts of Ohio, particularly Cincinnati and the southern portion of the state, have historically supported the Republican Party, Cleveland commonly breeds the strongest support in the state for the Democrats. At the local level, elections are nonpartisan. However, Democrats still dominate every level of government.
Cleveland is split between two congressional districts. Most of the western part of the city is in the 9th District, represented by Marcy Kaptur. Most of the eastern part of the city, as well as most of downtown, is in the 11th District, represented by Marcia Fudge. Both are Democrats.
During the 2004 Presidential election, although George W. Bush carried Ohio by 2.1%, John Kerry carried Cuyahoga County 66.6%–32.9%, his largest margin in any Ohio county. The city of Cleveland supported Kerry over Bush by the even larger margin of 83.3%–15.8%.The city of Cleveland operates on the mayor–council (strong mayor) form of government. The mayor is the chief executive of the city, and the office has been held by Frank G. Jackson since 2006. Previous mayors of Cleveland include progressive Democrat Tom L. Johnson, World War I era War Secretary and founder of BakerHostetler law firm Newton D. Baker, United States Supreme Court Justice Harold Hitz Burton, Republican Senator George V. Voinovich, two-term Ohio Governor and Senator, former United States Representative Dennis Kucinich of Ohio's 10th congressional district, Frank J. Lausche, and Carl B. Stokes, the first African American mayor of a major American city. The state of Ohio lost two Congressional seats as a result of the 2010 Census, which affects Cleveland's districts in the northeast part of the state.

Ex Output:
What are the specific names of the two individual congressional districts into which Cleveland is split?

Passage: With high school behind him, Andy Hardy decides that as an adult, it's time to start living his life. Judge Hardy had hoped that his son would go to college and study law, but Andy isn't sure that's what he wants to do so he heads off to New York City to find a job. Too proud to accept financial help from his longtime friend Betsy Booth, he at least lets her drive him to the city.
Andy soon meets there another young man who has just been fired as "office boy" at a midtown firm.  When Andy rushes there unannounced to apply for the vacancy, Betsy runs out of gasoline after patiently circling the congested streets for hours waiting for him to come out afterwards.  Andy lands the job, and even gets to repeatedly date the office receptionist, a more worldly woman who with the office staff are amused at his naivete and sometimes clumsiness.  He learns that daily expenses, including gifts and dates for his new girlfriend, quickly add up as well as mourning over the death of his new friend who dies.
Andy is nearly fired after, due to drowsiness, he mixes up two outgoing letters in the office mail.  Although ashamed to let his parents know of his difficulties, they hear of his circumstances from Betsy, and his father goes to bring him home.  After facing these several lessons of life, Andy concludes that he may still have some growing up to do.

Ex Output:

What is the first name of the person who lets Betsy drive them to the city?
