Problem: Israel:

During the siege of Jerusalem by the First Crusade in 1099, the Jewish inhabitants of the city fought side by side with the Fatimid garrison and the Muslim population who tried in vain to defend the city against the Crusaders. When the city fell, about 60,000 people were massacred, including 6,000 Jews seeking refuge in a synagogue. At this time, a full thousand years after the fall of the Jewish state, there were Jewish communities all over the country. Fifty of them are known and include Jerusalem, Tiberias, Ramleh, Ashkelon, Caesarea, and Gaza. According to Albert of Aachen, the Jewish residents of Haifa were the main fighting force of the city, and "mixed with Saracen [Fatimid] troops", they fought bravely for close to a month until forced into retreat by the Crusader fleet and land army. However, Joshua Prawer expressed doubt over the story, noting that Albert did not attend the Crusades and that such a prominent role for the Jews is not mentioned by any other source.[undue weight? – discuss]

Problem: The bacillus causing tuberculosis, M. tuberculosis, was identified and described on 24 March 1882 by Robert Koch. He received the Nobel Prize in physiology or medicine in 1905 for this discovery. Koch did not believe the bovine (cattle) and human tuberculosis diseases were similar, which delayed the recognition of infected milk as a source of infection. Later, the risk of transmission from this source was dramatically reduced by the invention of the pasteurization process. Koch announced a glycerine extract of the tubercle bacilli as a "remedy" for tuberculosis in 1890, calling it "tuberculin". While it was not effective, it was later successfully adapted as a screening test for the presence of pre-symptomatic tuberculosis. The World Tuberculosis Day was established on 24 March for this reason.
What year did World Tuberculosis Day start?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Besides the bit rate of an encoded piece of audio, the quality of MP3 files also depends on the quality of the encoder itself, and the difficulty of the signal being encoded. As the MP3 standard allows quite a bit of freedom with encoding algorithms, different encoders may feature quite different quality, even with identical bit rates. As an example, in a public listening test featuring two different MP3 encoders at about 128 kbit/s, one scored 3.66 on a 1–5 scale, while the other scored only 2.22.
To compare qualities, sound files are evaluated on a scale that ranges from 1 to what?
A: 5


Context and question: The distances passengers need to move within a large airport can be substantial. It is common for airports to provide moving walkways and buses. The Hartsfield–Jackson Atlanta International Airport has a tram that takes people through the concourses and baggage claim. Major airports with more than one terminal offer inter-terminal transportation, such as Mexico City International Airport, where the domestic building of Terminal 1 is connected by Aerotrén to Terminal 2, on the other side of the airport.
How far is the distance passengers need to move between buses?
Answer: unanswerable


Question: The term "modern" was coined in the 16th century to indicate present or recent times (ultimately derived from the Latin adverb modo, meaning "just now). The European Renaissance (about 1420–1630), which marked the transition between the Late Middle Ages and Early Modern times, started in Italy and was spurred in part by the rediscovery of classical art and literature, as well as the new perspectives gained from the Age of Discovery and the invention of the telescope and microscope, expanding the borders of thought and knowledge.
Is there an answer to this question: What term was coined in the 16th century to indicate present time?

Answer: modern


Question: With preceding legal institutions abolished, Gaddafi envisioned the Jamahiriya as following the Qur'an for legal guidance, adopting sharia law; he proclaimed "man-made" laws unnatural and dictatorial, only permitting Allah's law. Within a year he was backtracking, announcing that sharia was inappropriate for the Jamahiriya because it guaranteed the protection of private property, contravening The Green Book's socialism. His emphasis on placing his own work on a par with the Qur'an led conservative clerics to accuse him of shirk, furthering their opposition to his regime. In July, a border war broke out with Egypt, in which the Egyptians defeated Libya despite their technological inferiority. The conflict lasted one week before both sides agreed to sign a peace treaty that was brokered by several Arab states. That year, Gaddafi was invited to Moscow by the Soviet government in recognition of their increasing commercial relationship.
Is there an answer to this question: What tenet of sharia did Gaddafi believe was incompatible with socialism?

Answer:
protection of private property
