QUES: Naturally occurring glass, especially the volcanic glass obsidian, has been used by many Stone Age societies across the globe for the production of sharp cutting tools and, due to its limited source areas, was extensively traded. But in general, archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or ancient Egypt. The earliest known glass objects, of the mid third millennium BCE, were beads, perhaps initially created as accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing.

What kind of glass exists in nature?
What is the answer?

QUES: The multiple churches that form the Anglican Communion and the Continuing Anglican movement have different views on Marian doctrines and venerative practices given that there is no single church with universal authority within the Communion and that the mother church (the Church of England) understands itself to be both "catholic" and "Reformed". Thus unlike the Protestant churches at large, the Anglican Communion (which includes the Episcopal Church in the United States) includes segments which still retain some veneration of Mary.

Which church in the United States did Mary give universal authority to?
What is the answer?
ANS: unanswerable
QUES: The die is a negative image of the glass master: typically, several are made, depending on the number of pressing mills that are to make the CD. The die then goes into a press, and the physical image is transferred to the blank CD, leaving a final positive image on the disc. A small amount of lacquer is applied as a ring around the center of the disc, and rapid spinning spreads it evenly over the surface. Edge protection lacquer is applied before the disc is finished. The disc can then be printed and packed.

What is liquid is applied to the blank CD?
What is the answer?
ANS:
unanswerable
