Problem: Elevator:

Safety testing of mine shaft elevator rails is routinely undertaken. The method involves destructive testing of a segment of the cable. The ends of the segment are frayed, then set in conical zinc molds. Each end of the segment is then secured in a large, hydraulic stretching machine. The segment is then placed under increasing load to the point of failure. Data about elasticity, load, and other factors is compiled and a report is produced. The report is then analyzed to determine whether or not the entire rail is safe to use.

What part of the mine shaft requires routine testing?
---
A: elevator rails


Problem: Many flags of the Islamic world are green, as the color is considered sacred in Islam (see below). The flag of Hamas, as well as the flag of Iran, is green, symbolizing their Islamist ideology. The 1977 flag of Libya consisted of a simple green field with no other characteristics. It was the only national flag in the world with just one color and no design, insignia, or other details. Some countries used green in their flags to represent their country's lush vegetation, as in the flag of Jamaica, and hope in the future, as in the flags of Portugal and Nigeria. The green cedar of Lebanon tree on the Flag of Lebanon officially represents steadiness and tolerance.
What religion does Lebanon's flag represent?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Beginning with the advent of beat match DJing, in which Bronx DJs (Disc Jockeys) including Grandmaster Flash, Afrika Bambaataa and DJ Kool Herc extended the breaks of funk records, a major new musical genre emerged that sought to isolate the percussion breaks of hit funk, disco and soul songs. As hip hop's popularity grew, performers began speaking ("rapping") in sync with the beats, and became known as MCs or emcees. The Herculoids, made up of Herc, Coke La Rock, and DJ Clark Kent, were the earliest to gain major fame. The Bronx is referred to in hip-hop slang as "The Boogie Down Bronx", or just "The Boogie Down". This was hip-hop pioneer KRS-One's inspiration for his thought provoking group BDP, or Boogie Down Productions, which included DJ Scott La Rock. Newer hip hop artists from the Bronx include Big Pun, Lord Toriq and Peter Gunz, Camp Lo, Swizz Beatz, Drag-On, Fat Joe, Terror Squad and Corey Gunz.
What types of music did hip hop emerge from?
A: funk, disco and soul


Context and question: By March 2011, the market share of OS X in North America had increased to slightly over 14%. Whether the size of the Mac's market share and installed base is relevant, and to whom, is a hotly debated issue. Industry pundits have often called attention to the Mac's relatively small market share to predict Apple's impending doom, particularly in the early and mid-1990s when the company's future seemed bleakest. Others argue that market share is the wrong way to judge the Mac's success. Apple has positioned the Mac as a higher-end personal computer, and so it may be misleading to compare it to a budget PC. Because the overall market for personal computers has grown rapidly, the Mac's increasing sales numbers are effectively swamped by the industry's expanding sales volume as a whole. Apple's small market share, then, gives the impression that fewer people are using Macs than did ten years ago, when exactly the opposite is true. Soaring sales of the iPhone and iPad mean that the portion of Apple's profits represented by the Macintosh has declined in 2010, dropping to 24% from 46% two years earlier. Others try to de-emphasize market share, citing that it is rarely brought up in other industries. Regardless of the Mac's market share, Apple has remained profitable since Steve Jobs' return and the company's subsequent reorganization. Notably, a report published in the first quarter of 2008 found that Apple had a 14% market share in the personal computer market in the US, including 66% of all computers over $1,000. Market research indicates that Apple draws its customer base from a higher-income demographic than the mainstream personal computer market.
According to market research, who does Microsoft draw it's customer base from?
Answer: unanswerable


Question: Tourist hotspots in Portugal are Lisbon, Algarve, Madeira, Porto and the city of Coimbra, also, between 4-5 million religious pilgrims visit Fátima each year, where apparitions of the Blessed Virgin Mary to three shepherd children reportedly took place in 1917. The Sanctuary of Fátima is one of the largest Roman Catholic shrines in the world. The Portuguese government continues to promote and develop new tourist destinations, such as the Douro Valley, the island of Porto Santo, and Alentejo. Lisbon is the 16th European city which attracts the most tourists (with seven million tourists occupying the city's hotels in 2006, a number that grew 11.8% compared to previous year). Lisbon in recent years surpassed the Algarve as the leading tourist region in Portugal. Porto and Northern Portugal, especially the urban areas north of Douro River valley, was the tourist destination which grew most (11.9%) in 2006, surpassing Madeira (in 2010), as the third most visited destination.[citation needed]
Is there an answer to this question: What are the tourist hotspots in Portugal?

Answer: Lisbon, Algarve, Madeira, Porto and the city of Coimbra


Another occasionally used criterion for discriminating dialects from languages is that of linguistic authority, a more sociolinguistic notion. According to this definition, two varieties are considered dialects of the same language if (under at least some circumstances) they would defer to the same authority regarding some questions about their language. For instance, to learn the name of a new invention, or an obscure foreign species of plant, speakers of Bavarian German and East Franconian German might each consult a German dictionary or ask a German-speaking expert in the subject. By way of contrast, although Yiddish is classified by linguists as a language in the "Middle High German" group of languages, a Yiddish speaker would not consult a German dictionary to determine the word to use in such a case.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which language is classified by linguists as being in the Lower High German group?
Ah, so..
unanswerable
