Problem: Inimitability of the Quran (or "I'jaz") is the belief that no human speech can match the Quran in its content and form. The Quran is considered an inimitable miracle by Muslims, effective until the Day of Resurrection—and, thereby, the central proof granted to Muhammad in authentication of his prophetic status. The concept of inimitability originates in the Quran where in five different verses opponents are challenged to produce something like the Quran: "If men and sprites banded together to produce the like of this Quran they would never produce its like not though they backed one another." So the suggestion is that if there are doubts concerning the divine authorship of the Quran, come forward and create something like it. From the ninth century, numerous works appeared which studied the Quran and examined its style and content. Medieval Muslim scholars including al-Jurjani (d. 1078) and al-Baqillani (d. 1013) have written treatises on the subject, discussed its various aspects, and used linguistic approaches to study the Quran. Others argue that the Quran contains noble ideas, has inner meanings, maintained its freshness through the ages and has caused great transformations in individual level and in the history. Some scholars state that the Quran contains scientific information that agrees with modern science. The doctrine of miraculousness of the Quran is further emphasized by Muhammad's illiteracy since the unlettered prophet could not have been suspected of composing the Quran.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The rivalries between the Arab tribes had caused unrest in the provinces outside Syria, most notably in the Second Muslim Civil War of 680–692 CE and the Berber Revolt of 740–743 CE. During the Second Civil War, leadership of the Umayyad clan shifted from the Sufyanid branch of the family to the Marwanid branch. As the constant campaigning exhausted the resources and manpower of the state, the Umayyads, weakened by the Third Muslim Civil War of 744–747 CE, were finally toppled by the Abbasid Revolution in 750 CE/132 AH. A branch of the family fled across North Africa to Al-Andalus, where they established the Caliphate of Córdoba, which lasted until 1031 before falling due to the Fitna of al-Ándalus.
In what year CE did the Second Muslim Civil War end?
A: 692


Context and question: Alphanumeric LEDs are available in seven-segment, starburst and dot-matrix format. Seven-segment displays handle all numbers and a limited set of letters. Starburst displays can display all letters. Dot-matrix displays typically use 5x7 pixels per character. Seven-segment LED displays were in widespread use in the 1970s and 1980s, but rising use of liquid crystal displays, with their lower power needs and greater display flexibility, has reduced the popularity of numeric and alphanumeric LED displays.
 Which non-alphanumeric LED display can display all letters?
Answer: unanswerable


Question: Copper has been used since ancient times as a durable, corrosion resistant, and weatherproof architectural material. Roofs, flashings, rain gutters, downspouts, domes, spires, vaults, and doors have been made from copper for hundreds or thousands of years. Copper's architectural use has been expanded in modern times to include interior and exterior wall cladding, building expansion joints, radio frequency shielding, and antimicrobial indoor products, such as attractive handrails, bathroom fixtures, and counter tops. Some of copper's other important benefits as an architectural material include its low thermal movement, light weight, lightning protection, and its recyclability.
Is there an answer to this question: What is an important benefit to using copper as an architectural material?

Answer: low thermal movement


The two finalists were Kris Allen and Adam Lambert, both of whom had previously landed in the bottom three at the top five. Allen won the contest in the most controversial voting result since season two. It was claimed, later retracted, that 38 million of the 100 million votes cast on the night came from Allen's home state of Arkansas alone, and that AT&T employees unfairly influenced the votes by giving lessons on power-texting at viewing parties in Arkansas.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was accused of teaching the public how to power text for the winner?
Ah, so..
AT&T employees
