Question: Given the following context:  The earthquake swarm was noted on October 12, 2007 in the Prince George Citizen by citizen staff, three days after the earthquakes began. Scientists mentioned in the report were seismologist John Cassidy of Natural Resources Canada and volcanologist Catherine Hickson, who was part of the Geological Survey of Canada at the time. At the time of the report, scientists did not know the origin of the swarm. Seismologist John Cassidy stated, "the depth is enough to rule out hydrothermal but it's up in the air as to whether the cause is tectonic shifts or volcanic activity. If it is volcanic there are certain characteristics that we would expect, there's a tremor-like character to it. And so we'll be looking for the types of events that we see beneath volcanoes and we'll be looking to see if they're getting closer to the surface or if they're migrating at all."Even if the Nazko swarm were a warning of a volcanic eruption, Hickson doubted it would turn out to be a highly explosive eruption like those that can occur in subduction-zone volcanoes. "We're not talking about an injection of tonnes of ash many kilometers into the air like the 1980 Mount St. Helens eruption or the 1991 Mount Pinatubo eruption. We're talking about something very small, relatively localized that should have a fairly limited impact... but it'll be extremely exciting", Hickson said. If an eruption were to occur, Hickson suggested that it would be characterized by a lava fountain that sends globs of lava 100 m (330 ft) into the air. This is similar to those that occur in Hawaii. Hickson said that a Nazko eruption could be a tourist attraction, but warned that noxious gases such as carbon dioxide and sulfur dioxide would be released during the event.  answer the following question:  What is the first name of the person who doubted it would turn out to be a highly explosive eruption like those that can occur in subduction-zone volcanoes?
Answer: Catherine

Question: Given the following context:  Two days after the events of the first film, a traumatized and blood-covered Sarah escapes the cave with no memory of the events. She is taken to a hospital, where it is found that some of the blood on her belongs to Juno Kaplan. Sheriff Vaines takes his deputy Elen Rios, Sarah, and three spelunking specialists – Dan, Greg, and Cath – to the cave to find the missing women. The team members are sent down via an old mine shaft operated by the old, mysterious Ed Oswald. The group discovers Rebecca's mutilated body, causing Sarah to have flashbacks of the crawlers and causing Vaines to believe Sarah may be responsible for the girls' disappearance.  While crawling through a tunnel, she attacks Vaines and the others, causing the others to split up. Vaines runs to search for Sarah, and in the process is surprised by a crawler, and fires his gun in a panic, causing a minor collapse in the cavern which traps Cath, separating her from Rios, Dan, and Greg.  The three decide to find an alternate way around in order to try to free Cath and arrive in a room full of bones, where they find Holly's video camera. They watch it and realize the women were attacked by the crawlers. The three are then themselves attacked by crawlers and separated. Rios starts calling for help, alerting the crawlers to her location, but is rescued by Sarah.  The two then watch as a crawler kills Dan and drags his body away, prompting Sarah to inform Rios that the crawlers are blind and hunt via sound. After escaping from and killing a crawler, Cath finds Greg before the two escape from another crawler and find Sam's body. They decide to try to use her to swing across a chasm, but are attacked again. Greg sacrifices himself to buy time for Cath, but she ultimately does not survive.  answer the following question:  Who decides to use someone's body to escape across a chasm?
Answer: Cath

Question: Given the following context:  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.  answer the following question:  Which group tended to block any necessary reforms on the grounds of cost to the ratepayers?
Answer:
the Police Commission
