Question: Read the following paragraph and extract the answer for the question: What erupted causing the production of pyroclastic flows that melted summit glaciers and snow? At 3:06 pm, on November 13, 1985, Nevado del Ruiz began to erupt, ejecting dacitic tephra more than 30 kilometres (19 mi) into the atmosphere. The total mass of the erupted material (including magma) was 35 million tonnesonly 3% of the amount that erupted from Mount St. Helens in 1980. The eruption reached a value of 3 on the Volcanic Explosivity Index. The mass of the ejected sulfur dioxide was about 700,000 tonnes, or about 2% of the mass of the erupted solid material, making the eruption atypically sulfur-rich.The eruption produced pyroclastic flows that melted summit glaciers and snow, generating four thick lahars that raced down river valleys on the volcano's flanks. It also destroyed a small lake that was observed in Arenas crater several months before the eruption. Water in such volcanic lakes tends to be extremely salty and contain dissolved volcanic gases. The lake's hot, acidic water significantly accelerated the melting of the ice; this effect was confirmed by the large amounts of sulfates and chlorides found in the lahar flow. The lahars, formed of water, ice, pumice, and other rocks, mixed with clay as they travelled down the volcano's flanks. They ran down the volcano's sides at an average speed of 60 km per hour, eroding soil, dislodging rock, and destroying vegetation. After descending thousands of meters down the side of the volcano, the lahars were directed into all of the six river valleys leading from the volcano. While in the river valleys, the lahars grew to almost 4 times their original volume. In the Guali River, a lahar reached a maximum width of 50 meters (200 ft).One of the lahars virtually erased the town of Armero in Tolima, which lay in the Lagunilla River valley. Only one quarter of its 28,700 inhabitants survived. The second lahar, which descended through the valley of Chinchina River, killed about 1,800 people and destroyed about 400 homes in the town of Chinchina, in the department of Caldas. In total, over 23,000 people were killed and approximately 5,000 were injured....

Question: Read the following paragraph and extract the answer for the question: Where did Fred Davis board the flight? After leaving Sea Island Airport in Vancouver, British Columbia, the Canadian Pacific Air Lines Douglas DC-6 "Empress of Tokyo" airliner will overfly Shemya island in the Aleutians, before continuing to Tokyo, a 4,600 miles non-stop flight. Once airborne, reporter Fred Davis begins by explaining that airliners, like ships at sea, are bound by international regulations that prescribe certain precautions taken to ensure safety. The flight attendants (called stewardess at the time) take care to explain how to use the life preservers that are on board. Captain Bob McGuiness indicates that "George", the automatic pilot keeps the aircraft flying and allows the air crew to relax during most of the flight. Once reaching the point of no return, the captain, with assistance of the navigator, then plots the route to their final destination through the International Date Line. After 19 hours, the reporter and passengers glimpse the coastline of Japan, and the flight crew prepares everyone on board for a landing at Haneda Airport, Tokyo.
Answer: Vancouver, British Columbia

Question: Read the following paragraph and extract the answer for the question: What is the full name of the person that used the name Briarcliff for all his property? Briarcliff Manor's original settlement was known as Whitson's Corners for brothers John H., Richard, and Reuben Whitson, who owned adjoining farms in the area totaling 400 acres (160 ha). Whitson's Corners was named after the corner of Pleasantville and South State Roads, where John H. Whitson's house, the Crossways, stood from 1820 until the 1940s. The Briarcliff Congregational Church's parish house currently stands at its former location. The neighboring community of Scarborough was known as Weskora until it was renamed in 1864, after resident William Kemey's ancestral hometown in Yorkshire. After the community was incorporated into Briarcliff Manor in 1906, the New York Central and Hudson River Railroad put up a sign reading "Briarcliff West" at the village's Scarborough station. Soon afterward, attributed to the neighborhood's pride over their name, that sign was thrown into the Hudson River and replaced with the original Scarborough sign.Briarcliff Manor derives from "Brier Cliff", a compound of the English words "brier" and "cliff". The name originated in Ireland as that of the family home of John David Ogilby, a professor of ecclesiastical history at the General Theological Seminary. Ogilby had named his New York summer home Brier Cliff after his family home in Ireland. In 1890, Walter Law bought James Stillman's 236-acre (96 ha) Briarcliff Farm and further developed it, later using the name Briarcliff for all his property. Law's friend, Andrew Carnegie, called him "The Laird of Briarcliff Manor"; since the title appealed to all concerned, the village was named "Briarcliff Manor". By 1897, the village post office and railroad station bore the name Briarcliff Manor. The village (and its name) were approved by its residents in a September 12, 1902 referendum; the name prevailed over other suggestions, including "Sing Sing East". On November 21, 1902, the village of Briarcliff Manor was established.The village is also known by several other names. It is conversationally called "Briarcliff", and often...
