TASK DEFINITION: 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.
PROBLEM: Passage: At the time of the transfer of power, the state of Jammu and Kashmir (widely called "Kashmir") was ruled by Maharaja Hari Singh, a Hindu, although the state itself had a Muslim majority. Hari Singh was equally hesitant about acceding to either India or Pakistan, as either would have provoked adverse reactions in parts of his kingdom. He signed a Standstill Agreement with Pakistan and proposed one with India as well, but announced that Kashmir intended to remain independent. However, his rule was opposed by Sheikh Abdullah, the popular leader of Kashmir's largest political party, the National Conference, who demanded his abdication.Pakistan, attempting to force the issue of Kashmir's accession, cut off supplies and transport links. The chaos in Punjab resulting from Partition had also severed transport links with India, meaning that Kashmir's only links with the two dominions was by air. Rumours about atrocities against the Muslim population of Poonch by the Maharajah's forces caused the outbreak of civil unrest. Shortly thereafter, Pathan tribesmen from the North-West Frontier Province of Pakistan crossed the border and entered Kashmir. The invaders made rapid progress towards Srinagar. The Maharaja of Kashmir wrote to India, asking for military assistance. India required the signing of an Instrument of Accession and setting up an interim government headed by Sheikh Abdullah in return. The Maharaja complied, but Nehru declared that it would have to be confirmed by a plebiscite, although there was no legal requirement to seek such confirmation.Indian troops secured Jammu, Srinagar and the valley itself during the First Kashmir War, but the intense fighting flagged with the onset of winter, which made much of the state impassable. Prime Minister Nehru, recognising the degree of international attention brought to bear on the dispute, declared a ceasefire and sought UN arbitration, arguing that India would otherwise have to invade Pakistan itself, in view of its failure to stop the tribal incursions. The plebiscite was never held, and on 26 January 1950, the Constitution of India came into force in Kashmir, but with special provisions made for the state. India did not, however, secure administrative control over all of Kashmir. The northern and western portions of Kashmir came under Pakistan's control in 1947, and are today Pakistan-administered Kashmir. In the 1962 Sino-Indian War, China occupied Aksai Chin, the north-eastern region bordering Ladakh, which it continues to control and administer.

SOLUTION: What is the full name of the person whose rule was opposed?

PROBLEM: 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.

SOLUTION: What acts as reamers when they fail?

PROBLEM: Passage: When charter-boat skipper Jack O'Conner finds a gold Spanish dollar off the Florida Keys, he decides to go in search of a legendary hoard of Spanish doubloons sunk during the "Hundred Years Storm" of 1780. For, as Jack's friend Cap'n Billau reveals, the coin bears a clue to the treasure's whereabouts – one of four islands etched by the infamous pirate, Jacques Un-Oeil upon the original doubloon. At Billau's urging, Jack tracks down the two beautiful women who unknowingly hold the remaining clues.
Streetwise Sandy Sequoia's piece of eight came from her murdered drug dealer boyfriend in Miami. And lonely-heart Portia Pennington inherited her coin from her merchant tycoon grandfather, who died at sea in the "Hundred Years Storm" of 1893, while hunting for the lost gold.
Jack convinces the girls to go in search of the pirate treasure with him. But first, the two must learn to crew his 76' schooner; and then, all three adventurers must learn to trust one another, if they expect to navigate the treacheries of love and the unpredictable Caribbean.
As Jack introduces the girls to life at sea, he starts to fall in love with Sandy. All seems to be going well, until Jack discovers Sandy with drugs on his boat – a kilo of her dead boyfriend's cocaine (which she has steadily been using since coming aboard). He has Portia dump the coke overboard; and while Sandy wrestles to overcome her addiction, Jack turns his attentions to Portia.
When Sandy and Portia realize that Jack has seduced each of them in turn and convinced each to reveal to him the name of the island on her coin, they turn on him. Feeling betrayed and realizing that they no longer need Jack in order to sail the boat or find the gold, they maroon him on a small island and go after the sunken treasure themselves.

SOLUTION:
What is the last name of the person who is friends with Cap'n Billau?
