Article: From early in its development, ASCII was intended to be just one of several national variants of an international character code standard, ultimately published as ISO/IEC 646 (1972), which would share most characters in common but assign other locally useful characters to several code points reserved for "national use." However, the four years that elapsed between the publication of ASCII-1963 and ISO's first acceptance of an international recommendation during 1967 caused ASCII's choices for the national use characters to seem to be de facto standards for the world, causing confusion and incompatibility once other countries did begin to make their own assignments to these code points.

Question: When was ISO/IEC 646 published?
Ans: 1972


Article: Matter commonly exists in four states (or phases): solid, liquid and gas, and plasma. However, advances in experimental techniques have revealed other previously theoretical phases, such as Bose–Einstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quark–gluon plasma. For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470–380 BC).

Question: What new phase of matter can be considered with a focus on elementary particles?
Ans: quark–gluon plasma


Article: Most capacitors have numbers printed on their bodies to indicate their electrical characteristics. Larger capacitors like electrolytics usually display the actual capacitance together with the unit (for example, 220 μF). Smaller capacitors like ceramics, however, use a shorthand consisting of three numeric digits and a letter, where the digits indicate the capacitance in pF (calculated as XY × 10Z for digits XYZ) and the letter indicates the tolerance (J, K or M for ±5%, ±10% and ±20% respectively).

Question: How do larger capacitors present their electrical characteristics?
Ans: display the actual capacitance together with the unit (for example, 220 μF)


Article: While forming an integral part of the Christian calendar, particularly in Catholic regions, many Carnival traditions resemble those antedating Christianity. Italian Carnival is sometimes thought to be derived from the ancient Roman festivals of Saturnalia and Bacchanalia. The Saturnalia, in turn, may be based on the Greek Dionysia and Oriental festivals. For the start of the Roman Saturnalia, on December 17 authorities chose an enemy of the Roman people to represent the Lord of Misrule in each community. These men and women were forced to indulge in food and physical pleasures throughout the week, horribly murdered on December 25th: "destroying the forces of darkness".

Question: The Saturnalia is potentially based on what Greek festival?
Ans:
Dionysia
