If any boy produces an outstanding piece of work, it may be "Sent Up For Good", storing the effort in the College Archives for posterity. This award has been around since the 18th century. As Sending Up For Good is fairly infrequent, the process is rather mysterious to many of Eton's boys. First, the master wishing to Send Up For Good must gain the permission of the relevant Head of Department. Upon receiving his or her approval, the piece of work will be marked with Sent Up For Good and the student will receive a card to be signed by House Master, tutor and division master.

What action results in something being "Sent Up For Good?"
Answer: If any boy produces an outstanding piece of work

Britain's first use of brass occurred around the 3rd–2nd century BC. In North America, copper mining began with marginal workings by Native Americans. Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600. Copper metallurgy was flourishing in South America, particularly in Peru around 1000 AD; it proceeded at a much slower rate on other continents. Copper burial ornamentals from the 15th century have been uncovered, but the metal's commercial production did not start until the early 20th century.

When did Britain first use brass?
Answer: 3rd–2nd century BC

Alaska's economy depends heavily on increasingly expensive diesel fuel for heating, transportation, electric power and light. Though wind and hydroelectric power are abundant and underdeveloped, proposals for statewide energy systems (e.g. with special low-cost electric interties) were judged uneconomical (at the time of the report, 2001) due to low (less than 50¢/gal) fuel prices, long distances and low population. The cost of a gallon of gas in urban Alaska today is usually 30–60¢ higher than the national average; prices in rural areas are generally significantly higher but vary widely depending on transportation costs, seasonal usage peaks, nearby petroleum development infrastructure and many other factors.

Why were alternative energy sources judged uneconomical in 2001?
Answer:
low (less than 50¢/gal) fuel prices, long distances and low population
