Problem: Major European rivers flow from Switzerland, such as the Rhine, the Rhone, the Inn, the Ticino and the Po, all of which have headwaters in the Alps and flow into neighbouring countries, finally emptying into the North Sea, the Mediterranean Sea, the Adriatic Sea and the Black Sea. Other rivers such as the Danube have major tributaries flowing into them that originate in the Alps. The Rhone is second to the Nile as a freshwater source to the Mediterranean Sea; the river begins as glacial meltwater, flows into Lake Geneva, and from there to France where one of its uses is to cool nuclear power plants. The Rhine originates in a 30 square kilometre area in Switzerland and represents almost 60 percent of water exported from the country. Tributary valleys, some of which are complicated, channel water to the main valleys which can experience flooding during the snow melt season when rapid runoff causes debris torrents and swollen rivers.
Where do the major tributaries that flow through the Danube originate from?
---
Answer: the Alps


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The roots of hard rock can be traced back to the 1950s, particularly electric blues, which laid the foundations for key elements such as a rough declamatory vocal style, heavy guitar riffs, string-bending blues-scale guitar solos, strong beat, thick riff-laden texture, and posturing performances. Electric blues guitarists began experimenting with hard rock elements such as driving rhythms, distorted guitar solos and power chords in the 1950s, evident in the work of Memphis blues guitarists such as Joe Hill Louis, Willie Johnson, and particularly Pat Hare, who captured a "grittier, nastier, more ferocious electric guitar sound" on records such as James Cotton's "Cotton Crop Blues" (1954). Other antecedents include Link Wray's instrumental "Rumble" in 1958, and the surf rock instrumentals of Dick Dale, such as "Let's Go Trippin'" (1961) and "Misirlou" (1962).
What type of music known as the roots of hard rock was started in the 1940s?
A: unanswerable

Question: One of the notable authors of esoteric interpretation prior to the 12th century is Sulami (d. 1021) without whose work the majority of very early Sufi commentaries would not have been preserved. Sulami's major commentary is a book named haqaiq al-tafsir ("Truths of Exegesis") which is a compilation of commentaries of earlier Sufis. From the 11th century onwards several other works appear, including commentaries by Qushayri (d. 1074), Daylami (d. 1193), Shirazi (d. 1209) and Suhrawardi (d. 1234). These works include material from Sulami's books plus the author's contributions. Many works are written in Persian such as the works of Maybudi (d. 1135) kash al-asrar ("the unveiling of the secrets"). Rumi (d. 1273) wrote a vast amount of mystical poetry in his book Mathnawi. Rumi makes heavy use of the Quran in his poetry, a feature that is sometimes omitted in translations of Rumi's work. A large number of Quranic passages can be found in Mathnawi, which some consider a kind of Sufi interpretation of the Quran. Rumi's book is not exceptional for containing citations from and elaboration on the Quran, however, Rumi does mention Quran more frequently. Simnani (d. 1336) wrote two influential works of esoteric exegesis on the Quran. He reconciled notions of God's manifestation through and in the physical world with the sentiments of Sunni Islam. Comprehensive Sufi commentaries appear in the 18th century such as the work of Ismail Hakki Bursevi (d. 1725). His work ruh al-Bayan (the Spirit of Elucidation) is a voluminous exegesis. Written in Arabic, it combines the author's own ideas with those of his predecessors (notably Ibn Arabi and Ghazali), all woven together in Hafiz, a Persian poetry form.
Is there an answer to this question: Which Sufi commentator wrote the Spirit of Elucidation?

Answer: Ismail Hakki Bursevi


Problem: Umayyad Caliphate:

The final son of Abd al-Malik to become caliph was Hisham (724–43), whose long and eventful reign was above all marked by the curtailment of military expansion. Hisham established his court at Resafa in northern Syria, which was closer to the Byzantine border than Damascus, and resumed hostilities against the Byzantines, which had lapsed following the failure of the last siege of Constantinople. The new campaigns resulted in a number of successful raids into Anatolia, but also in a major defeat (the Battle of Akroinon), and did not lead to any significant territorial expansion.

When did Hisham's reign start?
---
A:
724
