QUES: Plymouth's early history extends to the Bronze Age, when a first settlement emerged at Mount Batten. This settlement continued as a trading post for the Roman Empire, until it was surpassed by the more prosperous village of Sutton, now called Plymouth. In 1620, the Pilgrim Fathers departed Plymouth for the New World and established Plymouth Colony the second English settlement in what is now the United States of America. During the English Civil War the town was held by the Parliamentarians and was besieged between 1642 and 1646.

In what year did the Pilgrim Fathers sail from Plymouth?
What is the answer?
ANS: 1620
QUES: The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a pure metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics.

What percentage of copper is destroyed by industrial machinery?
What is the answer?
ANS: unanswerable
QUES: Synthetic crude oil, also known as syncrude, is the output from a bitumen upgrader facility used in connection with oil sand production in Canada. Bituminous sands are mined using enormous (100 ton capacity) power shovels and loaded into even larger (400 ton capacity) dump trucks for movement to an upgrading facility. The process used to extract the bitumen from the sand is a hot water process originally developed by Dr. Karl Clark of the University of Alberta during the 1920s. After extraction from the sand, the bitumen is fed into a bitumen upgrader which converts it into a light crude oil equivalent. This synthetic substance is fluid enough to be transferred through conventional oil pipelines and can be fed into conventional oil refineries without any further treatment. By 2015 Canadian bitumen upgraders were producing over 1 million barrels (16010^3 m3) per day of synthetic crude oil, of which 75% was exported to oil refineries in the United States.

Who invented the process for removing bitumen from sands?
What is the answer?
ANS:
Dr. Karl Clark
