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.

Q: Passage: The boar was an important symbol in prehistoric Europe, where, according to the archaeologist Jennifer Foster, it was "venerated, eulogised, hunted and eaten ... for millennia, until its virtual extinction in recent historical time." Anglo-Saxon boar symbols follow a thousand years of similar iconography, coming after La Tène examples in the fourth century BC, Gaulish specimens three centuries later, and Roman boars in the fourth century AD. They likely represent a fused tradition of European and Mediterranean cultures. The boar is said to have been sacred to a mother goddess figure among linguistically Celtic communities in Iron Age Europe, while the Roman historian Tacitus, writing around the first century AD, suggested that the Baltic Aesti wore boar symbols in battle to invoke her protection. Boar-crested helmets are depicted on the turn-of-the-millennium Gundestrup cauldron, discovered in Denmark, and on a Torslunda plate from Sweden, made some five hundred years later. Though the Romans also included the boar in their stable of symbols—four legions, including the twentieth, adopted it as their emblem—it was only one among many. The boar nonetheless persisted in continental Germanic tradition during the nearly 400 years of Roman rule in Britain, such as in association with the Scandinavian gods Freyja and Freyr. Its return to prominence in the Anglo-Saxon period, as represented by the boars from Benty Grange, Wollaston, Guilden Morden, and Horncastle, may therefore suggest the post-Roman reintroduction of a Germanic tradition from Europe, rather than the continuation of a tradition in Britain through 400 years of Roman rule. Whatever its precise symbolism, the Anglo-Saxon boar appears to have been associated with protection; the Beowulf poet makes this clear, writing that boar symbols on helmets kept watch over the warriors wearing them.

A: What represents a fused tradition of European and Mediterranean cultures?

Q: 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.

A: What acts as reamers when they fail?

Q: Passage: In 1874, Disraeli's ambitious foreign policy, aimed at creating a British empire, is voted down by the House of Commons after a speech by his great rival, William Gladstone. Later, Disraeli receives the welcome news that the spendthrift Khedive of Egypt is in dire need of money and is willing to sell the controlling shares in the Suez Canal. The purchase of the canal would secure control of India, but Michael Probert, head of the Bank of England, makes it clear to Disraeli that he is vehemently opposed to any such plan. Disraeli then summons Hugh Myers, a leading Jewish banker.
Meanwhile, Lord Charles Deeford proposes to Lady Clarissa Pevensey. Although she is in love with him, she turns him down. He is content to enjoy his wealth and high social standing, and lacks the ambition she wants in a husband; further, she is a great admirer of the Prime Minister and Charles has no strong opinion about him. Disraeli, seeing promise in the young man and wanting Clarissa to be happy, convinces Charles to come work for him, and tells him about the canal purchase.
But he does not tell him about the spies. Russia, eager to seize India for itself, has assigned two spies to watch Disraeli: Mrs. Travers, who has entree to the highest social circles, and Mr. Foljambe. Disraeli was not fooled; he has hired Foljambe as his personal government secretary, the better to deceive him. When Foljambe asks Charles if Myers is there to provide financial backing for the purchase of the canal, Charles says nothing, but his manner makes it clear that Foljambe has guessed correctly. Mrs. Travers orders Foljambe to leave the country and warn their masters.
Disraeli soon discovers what has happened. When he decides to send an agent to the khedive immediately, Clarissa suggests he send Charles. Charles persuades the khedive to accept Myers' cheque in exchange for the shares, also proving his own worth to Clarissa.

A:
What is the full name of the person that Lady Clarissa is in love with?
