Problem: Kathmandu:

The base of the stupa has 108 small depictions of the Dhyani Buddha Amitabha. It is surrounded with a brick wall with 147 niches, each with four or five prayer wheels engraved with the mantra, om mani padme hum. At the northern entrance where visitors must pass is a shrine dedicated to Ajima, the goddess of smallpox. Every year the stupa attracts many Tibetan Buddhist pilgrims who perform full body prostrations in the inner lower enclosure, walk around the stupa with prayer wheels, chant, and pray. Thousands of prayer flags are hoisted up from the top of the stupa downwards and dot the perimeter of the complex. The influx of many Tibetan refugees from China has seen the construction of over 50 Tibetan gompas (monasteries) around Boudhanath.

What mantra is engraved on the stupa's prayer wheels?
---
A: om mani padme hum


Problem: The Canadian constitution determines that the Commander-in-Chief of the Canadian Armed Forces is the country's sovereign, who, since 1904, has authorized his or her viceroy, the governor general, to exercise the duties ascribed to the post of Commander-in-Chief and to hold the associated title since 1905. All troop deployment and disposition orders, including declarations of war, fall within the royal prerogative and are issued as Orders in Council, which must be signed by either the monarch or governor general. Under the Westminster system's parliamentary customs and practices, however, the monarch and viceroy must generally follow the advice of his or her ministers in Cabinet, including the prime minister and minister of national defence, who are accountable to the elected House of Commons.
Who must sign these orders for them to be valid?
---
Answer: the monarch or governor general

The modern concept of an abstract group developed out of several fields of mathematics. The original motivation for group theory was the quest for solutions of polynomial equations of degree higher than 4. The 19th-century French mathematician Évariste Galois, extending prior work of Paolo Ruffini and Joseph-Louis Lagrange, gave a criterion for the solvability of a particular polynomial equation in terms of the symmetry group of its roots (solutions). The elements of such a Galois group correspond to certain permutations of the roots. At first, Galois' ideas were rejected by his contemporaries, and published only posthumously. More general permutation groups were investigated in particular by Augustin Louis Cauchy. Arthur Cayley's On the theory of groups, as depending on the symbolic equation θn = 1 (1854) gives the first abstract definition of a finite group.
What modern concept was created from many fields of mathematics?
A: abstract group

Question: Perhaps the most famous raid by Oeselian pirates occurred in 1187, with the attack on the Swedish town of Sigtuna by Finnic raiders from Couronia and Oesel. Among the casualties of this raid was the Swedish archbishop Johannes. The city remained occupied for some time, contributing to its decline as a center of commerce in the 13th century and the rise of Uppsala, Visby, Kalmar and Stockholm. The Livonian Chronicle describes the Oeselians as using two kinds of ships, the piratica and the liburna. The former was a warship, the latter mainly a merchant ship. A piratica could carry approximately 30 men and had a high prow shaped like a dragon or a snakehead and a rectangular sail. Viking-age treasures from Estonia mostly contain silver coins and bars. Saaremaa has the richest finds of Viking treasures after Gotland in Sweden. This strongly suggests that Estonia was an important transit country during the Viking era.
Is there an answer to this question: What important figure was killed in the raid?

Answer: Swedish archbishop Johannes

To protect crops from wind and drought, the Grain Intendant Zhao Guo (趙過) created the alternating fields system (daitianfa 代田法) during Emperor Wu's reign. This system switched the positions of furrows and ridges between growing seasons. Once experiments with this system yielded successful results, the government officially sponsored it and encouraged peasants to use it. Han farmers also used the pit field system (aotian 凹田) for growing crops, which involved heavily fertilized pits that did not require plows or oxen and could be placed on sloping terrain. In southern and small parts of central Han-era China, paddy fields were chiefly used to grow rice, while farmers along the Huai River used transplantation methods of rice production.
What were paddy fields used for primarily to grow in smaller areas?
A:
rice
