QUES: Although most aspirated obstruents in the world's language are stops and affricates, aspirated fricatives such as [s], [f] or [] have been documented in Korean, in a few Tibeto-Burman languages, in some Oto-Manguean languages, and in the Siouan language Ofo. Some languages, such as Choni Tibetan, have up to four contrastive aspirated fricatives [s] [], [] and [x].

Choni Tibetan has how many unaspirated fricatives?
What is the answer?
ANS: unanswerable
QUES: The role of the gas is to prevent evaporation of the filament, without introducing significant heat losses. For these properties, chemical inertness and high atomic or molecular weight is desirable. The presence of gas molecules knocks the liberated tungsten atoms back to the filament, reducing its evaporation and allowing it to be operated at higher temperature without reducing its life (or, for operating at the same temperature, prolongs the filament life). It however introduces heat losses (and therefore efficiency loss) from the filament, by heat conduction and heat convection.

What is the purpose of the gas in a light bulb?
What is the answer?
ANS: to prevent evaporation of the filament, without introducing significant heat losses
QUES: A sociological comparative study by the Pew Research Center found that Jehovah's Witnesses in the United States ranked highest in statistics for getting no further than high school graduation, belief in God, importance of religion in one's life, frequency of religious attendance, frequency of prayers, frequency of Bible reading outside of religious services, belief their prayers are answered, belief that their religion can only be interpreted one way, belief that theirs is the only one true faith leading to eternal life, opposition to abortion, and opposition to homosexuality. In the study, Jehovah's Witnesses ranked lowest in statistics for having earned a graduate degree and interest in politics.

What do few Jehovah's Witnesses earn?
What is the answer?

a graduate degree
