Problem: ASCII:

Most early home computer systems developed their own 8-bit character sets containing line-drawing and game glyphs, and often filled in some or all of the control characters from 0–31 with more graphics. Kaypro CP/M computers used the "upper" 128 characters for the Greek alphabet. The IBM PC defined code page 437, which replaced the control-characters with graphic symbols such as smiley faces, and mapped additional graphic characters to the upper 128 positions. Operating systems such as DOS supported these code pages, and manufacturers of IBM PCs supported them in hardware. Digital Equipment Corporation developed the Multinational Character Set (DEC-MCS) for use in the popular VT220 terminal as one of the first extensions designed more for international languages than for block graphics. The Macintosh defined Mac OS Roman and Postscript also defined a set, both of these contained both international letters and typographic punctuation marks instead of graphics, more like modern character sets.

What did Digital Equipment Corporation develop?

A: Multinational Character Set (DEC-MCS)


Problem: Vacuum:

Historically, there has been much dispute over whether such a thing as a vacuum can exist. Ancient Greek philosophers debated the existence of a vacuum, or void, in the context of atomism, which posited void and atom as the fundamental explanatory elements of physics. Following Plato, even the abstract concept of a featureless void faced considerable skepticism: it could not be apprehended by the senses, it could not, itself, provide additional explanatory power beyond the physical volume with which it was commensurate and, by definition, it was quite literally nothing at all, which cannot rightly be said to exist. Aristotle believed that no void could occur naturally, because the denser surrounding material continuum would immediately fill any incipient rarity that might give rise to a void.

What can an atom not be understood by according to Greek philosophers?
---
A: unanswerable


Problem: Elizabeth II:

The Queen, who opened the 1976 Summer Olympics in Montreal, also opened the 2012 Summer Olympics and Paralympics in London, making her the first head of state to open two Olympic Games in two different countries. For the London Olympics, she played herself in a short film as part of the opening ceremony, alongside Daniel Craig as James Bond. On 4 April 2013, she received an honorary BAFTA for her patronage of the film industry and was called "the most memorable Bond girl yet" at the award ceremony.

When did Elizabeth open the Summer Olympics in Montreal?
---
A: 1976


Problem: Bern:

Bern was occupied by French troops in 1798 during the French Revolutionary Wars, when it was stripped of parts of its territories. It regained control of the Bernese Oberland in 1802, and following the Congress of Vienna of 1814, it newly acquired the Bernese Jura. At this time, it once again became the largest canton of the confederacy as it stood during the Restoration and until the secession of the canton of Jura in 1979. Bern was made the Federal City (seat of the Federal Assembly) within the new Swiss federal state in 1848.

When did the canton of Jura seceed?
---
A:
1979
