Context and question: A very small amount of water vapor inside a light bulb can significantly affect lamp darkening. Water vapor dissociates into hydrogen and oxygen at the hot filament. The oxygen attacks the tungsten metal, and the resulting tungsten oxide particles travel to cooler parts of the lamp. Hydrogen from water vapor reduces the oxide, reforming water vapor and continuing this water cycle. The equivalent of a drop of water distributed over 500,000 lamps will significantly increase darkening. Small amounts of substances such as zirconium are placed within the lamp as a getter to react with any oxygen that may bake out of the lamp components during operation.
Why does water decrease lamp darkening?
Answer: unanswerable
Context and question: Starting in 1982, dividends from the fund's annual growth have been paid out each year to eligible Alaskans, ranging from an initial $1,000 in 1982 (equal to three years' payout, as the distribution of payments was held up in a lawsuit over the distribution scheme) to $3,269 in 2008 (which included a one-time $1,200 "Resource Rebate"). Every year, the state legislature takes out 8% from the earnings, puts 3% back into the principal for inflation proofing, and the remaining 5% is distributed to all qualifying Alaskans. To qualify for the Permanent Fund Dividend, one must have lived in the state for a minimum of 12 months, maintain constant residency subject to allowable absences, and not be subject to court judgments or criminal convictions which fall under various disqualifying classifications or may subject the payment amount to civil garnishment.
How long must an Alaskan have lived in the state in order to receive a Permanent Fund Dividend?
Answer: minimum of 12 months
Context and question: North Carolina became one of the English Thirteen Colonies and with the territory of South Carolina was originally known as the Province of Carolina. The northern and southern parts of the original province separated in 1729. Originally settled by small farmers, sometimes having a few slaves, who were oriented toward subsistence agriculture, the colony lacked cities or towns. Pirates menaced the coastal settlements, but by 1718 the pirates had been captured and killed. Growth was strong in the middle of the 18th century, as the economy attracted Scots-Irish, Quaker, English and German immigrants. The colonists generally supported the American Revolution, as the number of Loyalists was smaller than in some other colonies.
What was the profession of most of the settlers in the Province of Carolina?
Answer:
small farmers
