Question: The answer to the question: What erupted causing the production of pyroclastic flows that melted summit glaciers and snow? is inside the article: 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...., can you guess it ?

[Q]: The answer to the question: What does the mouse trick Tom into doing? is inside the article: In Victorian London, an unseen criminal begins masterminding his "perfect plot on paper" which starts with a robbery taking place and three cats stealing a pink diamond. Three constables spot them and give chase, but the cats escape to the rooftops and glide off into the night, giving the stolen diamond to a mysterious horseman. The next day, Dr. Watson rushes to 221B in Baker Street and informs his colleague Sherlock Holmes of the robbery. Holmes then calls his pet mouse Jerry to bring him a copy of the Times. Jerry heads out to buy it while encountering Tom on the way, who also has something for Holmes. Jerry returns to Holmes' flat and hands him the paper or what was left of it after the chase. Reading a letter Tom had given to them for the night, Holmes and Watson decide to go to the Bruce Nigel Theatre where a performer named Red is seen. Holmes is told that she is being blackmailed and Holmes suggests who the perpetrator might be Professor Moriarty. Holmes deduces that the Star of Punjab, a diamond that is light sensitive to the light of a solar eclipse which was to happen the following day, is to be stolen by the mastermind of the blackmail. At the Punjab Embassy, Spike and Tyke are assigned to guard the Star of Punjab. Spike begins to teach Tyke how to be a good dog guard, but the three cats from the previous night steal the diamond while an unfocused Spike is not looking. The three cats then leave a small button and retreat. They climb out through a hole in Red's home that leads to the tunnel and escape before Holmes, Tom and Jerry arrive. Upon arriving, Jerry tricks Tom into stepping into a broken board and the trio check the tunnel. Finding sawdust, they retreat after hearing Tyke sounding the alarm. Holmes and Watson leave to find the shop where the button came from, while Tom and Jerry are left to take Red to Holmes' flat., can you guess it ?

input: Please answer the following: The answer to the question: What organization commissioned a "site characterization study" to the company that sold flooring for use in basketball courts? is inside the article: In 1967, Pennsylvania leased the reactor complex to the Nuclear Materials and Equipment Corporation (NUMEC), which already had a federal license to work with nuclear materials. NUMEC, which soon became a subsidiary of Atlantic-Richfield Corporation (ARCO), set up a large irradiator in what had been the reactor pool. The irradiator contained over 1 million curies of cobalt-60 to produce intense gamma rays, which were used to sterilize medical equipment and irradiate food and wood. In the spring of 1967 the state had concluded that radiation contamination at the Quehanna site "could never be completely cleaned up", and so was glad to find a tenant with nuclear experience. A group of NUMEC employees discovered that irradiating hardwood treated with plastics produced very durable flooring. In 1978 they formed PermaGrain Products, Inc. as a separate company from ARCO, and purchased the rights to the process as well as "the main irradiator, a smaller shielded irradiator and related equipment". PermaGrain sold the flooring for use in basketball courts and gymnasiums, and was the longest occupant of the Quehanna facility, operating there from 1978 to December 2002. PermaGrain also let Neutron Products, Inc., a Maryland company, do cobalt-60 work in its hot cells, which required an amendment of their license from the Nuclear Regulatory Commission (NRC, the successor to the AEC).In 1993, strontium-90 contamination in the reactor facility led the NRC to require PermaGrain to begin decontamination work, and the Pennsylvania DEP commissioned a "site characterization study". In 1998, a firm named NES began the cleanup work; they changed their name to Scientech in 1999 and to EnergySolutions in 2006. The cleanup was originally estimated to take six months; by 2006 it had taken 8 years and cost $30 million. According to the Pennsylvania Department of Environmental Protection's (DEP) Bureau of Radiation Protection: "Inadequate characterization of the site and the presence of ongoing industrial operations resulted in many..., can you guess it ?
