Problem: In November 2013, Somalia received its first fiber optic connection. The country previously had to rely on expensive satellite links due to the civil conflict, which limited internet usage. However, residents now have access to broadband internet cable for the first time after an agreement reached between Hormuud Telecom and Liquid Telecom. The deal will see Liquid Telecom link Hormuud to its 17,000 km (10,500 mile) network of terrestrial cables, which will deliver faster internet capacity. The fiber optic connection will also make online access more affordable to the average user. This in turn is expected to further increase the number of internet users. Dalkom Somalia reached a similar agreement with the West Indian Ocean Cable Company (WIOCC) Ltd, which it holds shares in. Effective the first quarter of 2014, the deal will establish fiber optic connectivity to and from Somalia via the EASSy cable. The new services are expected to reduce the cost of international bandwidth and to better optimize performance, thereby further broadening internet access. Dalkom Somalia is concurrently constructing a 1,000 square mile state-of-the-art data center in Mogadishu. The site will facilitate direct connection into the international fiber optic network by hosting equipment for all of the capital's ISPs and telecommunication companies.
How long is Hormuud's cable network?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Muhammad Husayn Tabatabaei says that according to the popular explanation among the later exegetes, ta'wil indicates the particular meaning a verse is directed towards. The meaning of revelation (tanzil), as opposed to ta'wil, is clear in its accordance to the obvious meaning of the words as they were revealed. But this explanation has become so widespread that, at present, it has become the primary meaning of ta'wil, which originally meant "to return" or "the returning place". In Tabatabaei's view, what has been rightly called ta'wil, or hermeneutic interpretation of the Quran, is not concerned simply with the denotation of words. Rather, it is concerned with certain truths and realities that transcend the comprehension of the common run of men; yet it is from these truths and realities that the principles of doctrine and the practical injunctions of the Quran issue forth. Interpretation is not the meaning of the verse—rather it transpires through that meaning, in a special sort of transpiration. There is a spiritual reality—which is the main objective of ordaining a law, or the basic aim in describing a divine attribute—and then there is an actual significance that a Quranic story refers to.
What can interpretation find that lies the behind the inapparent events referred to in a Quranic story?
A: unanswerable


Context and question: This narrative draws on the Nidānakathā of the Jataka tales of the Theravada, which is ascribed to Buddhaghoṣa in the 5th century CE. Earlier biographies such as the Buddhacarita, the Lokottaravādin Mahāvastu, and the Sarvāstivādin Lalitavistara Sūtra, give different accounts. Scholars are hesitant to make unqualified claims about the historical facts of the Buddha's life. Most accept that he lived, taught and founded a monastic order, but do not consistently accept all of the details contained in his biographies.
Most accept that Buddha lived and taught in what type of order?
Answer: monastic


Question: In the 1960s, American and British blues and rock bands began to modify rock and roll by adding harder sounds, heavier guitar riffs, bombastic drumming, and louder vocals, from electric blues. Early forms of hard rock can be heard in the work of Chicago blues musicians Elmore James, Muddy Waters, and Howlin' Wolf, The Kingsmen's version of "Louie Louie" (1963) which made it a garage rock standard, and the songs of rhythm and blues influenced British Invasion acts, including "You Really Got Me" by The Kinks (1964), "My Generation" by The Who (1965), "Shapes of Things" (1966) by The Yardbirds and "(I Can't Get No) Satisfaction" (1965) by The Rolling Stones. From the late 1960s, it became common to divide mainstream rock music that emerged from psychedelia into soft and hard rock. Soft rock was often derived from folk rock, using acoustic instruments and putting more emphasis on melody and harmonies. In contrast, hard rock was most often derived from blues rock and was played louder and with more intensity.
Is there an answer to this question: Who were three Chicago blues players who influenced hard rock?

Answer: Elmore James, Muddy Waters, and Howlin' Wolf


In Northern Germany, Netherlands, northern Poland, Denmark, and the Baltic countries local building stone was unavailable but there was a strong tradition of building in brick. The resultant style, Brick Gothic, is called "Backsteingotik" in Germany and Scandinavia and is associated with the Hanseatic League. In Italy, stone was used for fortifications, but brick was preferred for other buildings. Because of the extensive and varied deposits of marble, many buildings were faced in marble, or were left with undecorated façade so that this might be achieved at a later date.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What building style was the Hanseatic League disconnected with in Germany and Scandinavia?
Ah, so..
unanswerable
