Problem: 2008 Sichuan earthquake:

In 2002, Chinese geologist Chen Xuezhong published a Seismic Risk Analysis study in which he came to the conclusion that beginning with 2003, attention should be paid to the possibility of an earthquake with a magnitude of over 7.0 occurring in Sichuan region. He based his study on statistical correlation. That Sichuan is a seismically active area has been discussed for years prior to the quake, though few studies point to a specific date and time.

What strength did he predict the next quake in Sichuan to be?
---
A: over 7.0


Problem: DEC operating systems (OS/8, RT-11, RSX-11, RSTS, TOPS-10, etc.) used both characters to mark the end of a line so that the console device (originally Teletype machines) would work. By the time so-called "glass TTYs" (later called CRTs or terminals) came along, the convention was so well established that backward compatibility necessitated continuing the convention. When Gary Kildall cloned RT-11 to create CP/M he followed established DEC convention. Until the introduction of PC DOS in 1981, IBM had no hand in this because their 1970s operating systems used EBCDIC instead of ASCII and they were oriented toward punch-card input and line printer output on which the concept of carriage return was meaningless. IBM's PC DOS (also marketed as MS-DOS by Microsoft) inherited the convention by virtue of being a clone of CP/M, and Windows inherited it from MS-DOS.
When was the introduction of IBM?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the Regal era, a rex sacrorum (king of the sacred rites) supervised regal and state rites in conjunction with the king (rex) or in his absence, and announced the public festivals. He had little or no civil authority. With the abolition of monarchy, the collegial power and influence of the Republican pontifices increased. By the late Republican era, the flamines were supervised by the pontifical collegia. The rex sacrorum had become a relatively obscure priesthood with an entirely symbolic title: his religious duties still included the daily, ritual announcement of festivals and priestly duties within two or three of the latter but his most important priestly role – the supervision of the Vestals and their rites – fell to the more politically powerful and influential pontifex maximus.
What group's power increased after the rise of the Roman Republic?
A: Republican pontifices


Context and question: Through the use of multidimensional scaling, psychologists can map out similar emotional experiences, which allows a visual depiction of the "emotional distance" between experiences. A further step can be taken by looking at the map's dimensions of the emotional experiences. The emotional experiences are divided into two dimensions known as valence (how negative or positive the experience feels) and arousal (how energized or enervated the experience feels). These two dimensions can be depicted on a 2D coordinate map. This two-dimensional map was theorized to capture one important component of emotion called core affect. Core affect is not the only component to emotion, but gives the emotion its hedonic and felt energy.
Along with valence, what is the other of the three dimensions used to map emotional experiences?
Answer: unanswerable


Question: Apple debuted the iTunes Wi-Fi Music Store on September 5, 2007, in its Media Event entitled "The Beat Goes On...". This service allows users to access the Music Store from either an iPhone or an iPod Touch and download songs directly to the device that can be synced to the user's iTunes Library over a WiFi connection, or, in the case of an iPhone, the telephone network.
Is there an answer to this question: In what year was the iTunes Wi-Fi Music Store introduced?

Answer: 2007


In June 2005, presidential elections were held for the first time since the coup that deposed Ialá. Ialá returned as the candidate for the PRS, claiming to be the legitimate president of the country, but the election was won by former president João Bernardo Vieira, deposed in the 1999 coup. Vieira beat Malam Bacai Sanhá in a runoff election. Sanhá initially refused to concede, claiming that tampering and electoral fraud occurred in two constituencies including the capital, Bissau.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who won the election?
Ah, so..
João Bernardo Vieira
