Q: Read the following paragraph and extract the answer for the question: What may include a motor to drive the rotation? The ice must be cut through, broken up, or melted. Tools can be directly pushed into snow and firn (snow that is compressed, but not yet turned to ice, which typically happens at a depth of 60 metres (200 ft) to 120 metres (390 ft)); this method is not effective in ice, but it is perfectly adequate for obtaining samples from the uppermost layers. For ice, two options are percussion drilling and rotary drilling. Percussion drilling uses a sharp tool such as a chisel, which strikes the ice to fracture and fragment it. More common are rotary cutting tools, which have a rotating blade or set of blades at the bottom of the borehole to cut away the ice. For small tools the rotation can be provided by hand, using a T-handle or a carpenter's brace. Some tools can also be set up to make use of ordinary household power drills, or they may include a motor to drive the rotation. If the torque is supplied from the surface, then the entire drill string must be rigid so that it can be rotated; but it is also possible to place a motor just above the bottom of the drill string, and have it supply power directly to the drill bit.If the ice is to be melted instead of cut, then heat must be generated. An electrical heater built into the drill string can heat the ice directly, or it can heat the material it is embedded in, which in turn heats the ice. Heat can also be sent down the drill string; hot water or steam pumped down from the surface can be used to heat a metal drillhead, or the water or steam can be allowed to emerge from the drillhead and melt the ice directly. In at least one case a drilling project experimented with heating the drillhead on the surface, and then lowering it into the hole.Many ice drilling locations are very difficult to access, and drills must be designed so that they can be transported to the drill site. The equipment should be as light and portable as possible. It is helpful if the equipment can be broken down so that the individual components can be carried separately, thus reducing...
A: Some tools
Question: Read the following paragraph and extract the answer for the question: In the city with 7.0% African origin, what percentage of residents speak Spanish at home? According to the 2012-2016 American Community Survey (ACS), the racial makeup of the city was 65.7% Caucasian, 14.1% Asian, 7.0% of African origin, 6.6% Hispanic or Latino of any race, 0.4% Native American, 0.9% Pacific Islander, 0.2% other races, and 5.6% two or more races. According to the 2010 United States Census, Seattle had a population of 608,660 with a racial and ethnic composition as follows: White: 69.5% (Non-Hispanic Whites: 66.3%) Asian: 13.8% (4.1% Chinese, 2.6% Filipino, 2.2% Vietnamese, 1.3% Japanese, 1.1% Korean, 0.8% Indian, 0.3% Cambodian, 0.3% Laotian, 0.2% Pakistanis, 0.2% Indonesian, 0.2% Thai) Black or African American: 7.9% Hispanic or Latino (of any race): 6.6% (4.1% Mexican, 0.3% Puerto Rican, 0.2% Guatemalan, 0.2% Salvadoran, 0.2% Cuban) American Indian and Alaska Native: 0.8% Native Hawaiian and Other Pacific Islander: 0.4% Other race: 2.4% Two or more races: 5.1%Seattle's population historically has been predominantly white. The 2010 census showed that Seattle was one of the whitest big cities in the country, although its proportion of white residents has been gradually declining. In 1960, whites comprised 91.6% of the city's population, while in 2010 they comprised 69.5%. According to the 20062008 American Community Survey, approximately 78.9% of residents over the age of five spoke only English at home. Those who spoke Asian languages other than Indo-European languages made up 10.2% of the population, Spanish was spoken by 4.5% of the population, speakers of other Indo-European languages made up 3.9%, and speakers of other languages made up 2.5%.
Answer: 4.5%
Question: Read the following paragraph and extract the answer for the question: What is the first name of the person who Allen demanded surrender the fort "In the name of the Great Jehovah and the Continental Congress!?" In 1775, Fort Ticonderoga, in disrepair, was still manned by a token British force. They found it extremely useful as a supply and communication link between Canada (which they had taken over after their victory in the Seven Years' War) and New York. On May 10, 1775, less than one month after the American Revolutionary War was ignited with the battles of Lexington and Concord, the British garrison of 48 soldiers was surprised by a small force of Green Mountain Boys, along with militia volunteers from Massachusetts and Connecticut, led by Ethan Allen and Benedict Arnold. Allen claims to have said, "Come out you old Rat!" to the fort's commander, Captain William Delaplace. He also later said that he demanded that the British commander surrender the fort "In the name of the Great Jehovah and the Continental Congress!"; however, his surrender demand was made to Lieutenant Jocelyn Feltham and not the fort's commander, who did later appear and surrender his sword.With the capture of the fort, the Patriot forces obtained a large supply of cannons and other armaments, much of which Henry Knox transported to Boston during the winter of 17751776. Ticonderoga's cannons were instrumental in ending the Siege of Boston when they were used to fortify Dorchester Heights. With Dorchester Heights secured by the Patriots, the British were forced to evacuate the city in March 1776. The capture of Fort Ticonderoga by the Patriots made communication between the British Canadian and American commands much more difficult. Benedict Arnold remained in control of the fort until 1,000 Connecticut troops under the command of Benjamin Hinman arrived in June 1775. Because of a series of political maneuvers and miscommunications, Arnold was never notified that Hinman was to take command. After a delegation from Massachusetts (which had issued Arnold's commission) arrived to clarify the matter, Arnold resigned his commission and departed, leaving the fort in Hinman's hands.

William
