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.

Passage: Most historians describe the contacts between the Mongol Empire and the Western Europeans as a series of attempts, missed opportunities, and failed negotiations. Christopher Atwood, in the 2004 Encyclopedia of Mongolia and the Mongol Empire, summed up the relations between Western Europe and the Mongols: "Despite numerous envoys and the obvious logic of an alliance against mutual enemies, the papacy and the Crusaders never achieved the often-proposed alliance against Islam."A few other historians argue there was an actual alliance, but do not agree on the details: Jean Richard wrote that an alliance began around 1263. Reuven Amitai stated that the closest thing to actual Mongol-Frankish military coordination was when Prince Edward of England attempted to coordinate activities with Abaga in 1271. Amitai also mentioned the other attempts towards cooperation, but said, "In none of these episodes, however, can we speak of Mongols and troops from the Frankish West being on the Syrian mainland at the same time." Timothy May described the alliance as having its peak at the Council of Lyon in 1274, but that it began to unravel in 1275 with the death of Bohemond, and May too admitted that the forces never engaged in joint operations. Alain Demurger, in his own book The Last Templar, said that an alliance was not sealed until 1300.There also continues to be debate about whether or not an alliance would have been a wise idea, and whether the Crusaders at that point in history were even relevant to the Persian-Mongol conflict. The 20th-century historian Glenn Burger said, "The refusal of the Latin Christian states in the area to follow Hethum's example and adapt to changing conditions by allying themselves with the new Mongol empire must stand as one of the saddest of the many failures of Outremer." This was similar to the view of Steven Runciman, who argued, "Had the Mongol alliance been achieved and honestly implemented by the West, the existence of Outremer would almost certainly have been prolonged. The Mameluks would have been crippled if not destroyed; and the Ilkhanate of Persia would have survived as a power friendly to the Christians and the West". However, David Nicolle, describing the Mongols as "potential allies", said that early historians were writing from the benefit of hindsight, and that overall the major players were the Mamluks and the Mongols, with Christians just "pawns in a greater game.".

Ex Output:
Who did Jean Richard claim had an alliance around 1263?

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: In the Old West, a calm man named Tommy, known as "White Knife" by the Native American tribe who raised him after his mother was murdered is to marry a member of the tribe named Smoking Fox. Following a run-in with a deranged, Native American-racist food proprietor named Clem and the Left-Eye Gang (who have all removed their right eyes to join) led by Will Patch, Tommy is visited by a bank robber named Frank Stockburn who claims to be Tommy's biological father. Tommy explains to Frank that his mother was shot by a man with a tattooed hand when she was escorting him to school during his childhood. Frank also tells Tommy that he is dying of consumption and had amassed $50,000 which he buried in a meadow next to a pine tree and is offering to Tommy and the Natives. The next day, a group of bandits with connections to Frank come to the village, led by the ruthless Cicero who wants Frank to give them his "big score" he gained a while back. Frank has the bandits kidnap him so he can lead them to the $50,000 at the so-called "Singing Windmill", in return for the bandits not attacking Tommy or the Indians. With no time to search the meadow and find the money, and to live to his tribe's standards, Tommy decides to resort to stealing from dishonorable persons (corrupt politicians, racist bankers, and thugs alike) to obtain the amount needed and save his father. During his quest, Tommy discovers that he has 5 half-brothers: Mexican burro rider Ramon whose innkeeper mother had a fling with Frank; mentally challenged yet happy-go-lucky Lil' Pete whose strong neck makes him immune to hanging; feral mountain-man Herm who speaks incomprehensibly while having helped his mother sell their moonshine.

Ex Output:

What alternate name does Frank Stockburn's son go by?
