Question: Passage: In manufacturing the glass bulb, a type of "ribbon machine" is used. A continuous ribbon of glass is passed along a conveyor belt, heated in a furnace, and then blown by precisely aligned air nozzles through holes in the conveyor belt into molds. Thus the glass bulbs are created. After the bulbs are blown, and cooled, they are cut off the ribbon machine; a typical machine of this sort produces 50,000 bulbs per hour. The filament and its supports are assembled on a glass stem, which is fused to the bulb. The air is pumped out of the bulb, and the evacuation tube in the stem press is sealed by a flame. The bulb is then inserted into the lamp base, and the whole assembly tested.

Answer: What type of machine is not used in manufacturing light bulbs?


Question: Passage: As the initial punk movement dwindled, vibrant new scenes began to coalesce out of a variety of bands pursuing experimental sounds and wider conceptual territory in their work. Many of these artists drew on backgrounds in art and viewed their music as invested in particular political or aesthetic agendas. British music publications such as the NME and Sounds developed an influential part in this nascent post-punk culture, with writers like Jon Savage, Paul Morley and Ian Penman developing a dense (and often playful) style of criticism that drew on critical theory, radical politics and an eclectic variety of other sources.

Answer: What happened as the pot-punk movement dwindled?


Question: Passage: ^Note 5: The North Carolina Constitution of 1776 disestablished the Anglican church, but until 1835 the NC Constitution allowed only Protestants to hold public office. From 1835-1876 it allowed only Christians (including Catholics) to hold public office. Article VI, Section 8 of the current NC Constitution forbids only atheists from holding public office. Such clauses were held by the United States Supreme Court to be unenforceable in the 1961 case of Torcaso v. Watkins, when the court ruled unanimously that such clauses constituted a religious test incompatible with First and Fourteenth Amendment protections.

Answer:
When did the North Carolina Constitution establish the Anglican church?
