In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Passage: The second half of the 19th century has often been called the Heroic Age of Antarctic Exploration. The inhospitable and dangerous Arctic and Antarctic regions appealed powerfully to the imagination of the age, not as lands with their own ecologies and cultures, but as challenges to be conquered by technological ingenuity and manly daring.
Salomon August Andrée shared these enthusiasms, and proposed a plan for letting the wind propel a hydrogen balloon from Svalbard across the Arctic Sea to the Bering Strait, to fetch up in Alaska, Canada, or Russia, and passing near or even right over the North Pole on the way. Andrée was an engineer at the patent office in Stockholm, with a passion for ballooning.
He bought his own balloon, the Svea, in 1893 and made nine journeys with it, starting from Gothenburg or Stockholm and traveling a combined distance of 1,500 kilometres (930 mi). In the prevailing westerly winds, the Svea flights had a strong tendency to carry him uncontrollably out to the Baltic Sea and drag his basket perilously along the surface of the water or slam it into one of the many rocky islets in the Stockholm archipelago.
On one occasion he was blown clear across the Baltic to Finland. His longest trip was due east from Gothenburg, across the breadth of Sweden and out over the Baltic to Gotland. Even though he saw a lighthouse and heard breakers off Öland, he remained convinced that he was traveling over land and seeing lakes.During a couple of Svea flights, Andrée tested and tried out the drag-rope steering technique which he had developed and wanted to use on his projected North Pole expedition. Drag ropes, which hang from the balloon basket and drag part of their length on the ground, are designed to counteract the tendency of lighter-than-air craft to travel at the same speed as the wind, a situation that makes steering by sails impossible. The friction of the ropes was intended to slow the balloon to the point where the sails would have an effect (beyond that of making the balloon rotate on its axis). Andrée reported, and presumably believed, that with drag rope/sails steering he had succeeded in deviating about ten degrees either way from the wind direction.
This notion is rejected by modern balloonists; the Swedish Ballooning Association maintains that Andrée's belief that he had deviated from the wind was mistaken, being misled by inexpertise and a surfeit of enthusiasm in an environment of variable winds and poor visibility. Use of drag ropes—prone to snapping, falling off, or becoming entangled with each other or the ground, in addition to being ineffective—is not considered by any modern expert to be a useful steering technique. 
Question: What was the name of the technique Andrée tried on a couple of Svea flights?
drag-rope steering technique.

Passage: After her husband Martin completes a four-year prison sentence for insider trading, Emily Taylor drives into a wall in an apparent suicide attempt. Jonathan Banks, her assigned psychiatrist, prescribes a series of antidepressants, but none work. Jonathan contacts Emily's previous psychiatrist, Victoria Siebert, who suggests an experimental new drug, Ablixa. The drug seems to help Emily, but gives her sleepwalking episodes as a side effect.
One night, Emily stabs Martin to death while sleepwalking. Jonathan fights for Emily's acquittal in court. She pleads insanity and is declared not guilty on the condition that she stays in a psychiatric hospital until cleared by Jonathan. The publicity destroys Jonathan's reputation, and his colleagues assume negligence on his part.
Jonathan discovers evidence that Emily is lying; she was not depressed and faked her suicide attempts. He also discovers someone may have profited from Ablixa's fall in stock value. He interviews Emily after administering what he claims is a truth serum that will make her drowsy. Though the serum is actually saline water, she feigns drowsiness, confirming Jonathan's suspicion that she is deceiving him. When he confronts Victoria with his findings, she mails photographs to his wife Deirdre implying he had an affair with Emily. Deirdre leaves him, taking her son with her. 
Question: What is the full name of the person who begins sleepwalking?
Emily Taylor.

Passage: Concurrently with designing churches and building railways, Sharpe was heavily involved in the civic life of Lancaster, particularly in pioneering sanitary reform.  By political persuasion he was a Conservative, and in 1837 he joined the local Heart of Oak Club, the core of the Lancaster Conservative Association. He was elected a town councillor for Castle Ward in 1841, a post he held for ten years, and in 1843 was appointed the town council's representative on the local Police Commission.  He was also a visitor to the national schools, and in November 1848 he was elected as mayor for year, at that time a position more like that of a "chief magistrate". Through these offices he became aware of the unsatisfactory state of sanitation in the town, and resolved to improve it. The town was overcrowded, it suffered from poor housing, open sewers, overflowing cesspits, and a very poor water supply, mainly from wells polluted by infiltration.  Many people suffered from typhus, and in 1848 there was an outbreak of cholera. The Police Commission had been established in Lancaster in 1825 with a wider role than suggested by its title, including "cleansing, lighting and watching" the town. However, there was constant friction between the Police Commission and the Town Council, the former tending to block any necessary reforms on the grounds of cost to the ratepayers.  The conflict was unresolved until the two bodies merged in 1849. The functions of the new body included the establishment of the first Lancaster Board of Health. 
Question: Which group tended to block any necessary reforms on the grounds of cost to the ratepayers?

the Police Commission.
