Problem: The Cubism of Picasso, Braque and Gris had more than a technical or formal significance, and the distinct attitudes and intentions of the Salon Cubists produced different kinds of Cubism, rather than a derivative of their work. "It is by no means clear, in any case," wrote Christopher Green, "to what extent these other Cubists depended on Picasso and Braque for their development of such techniques as faceting, 'passage' and multiple perspective; they could well have arrived at such practices with little knowledge of 'true' Cubism in its early stages, guided above all by their own understanding of Cezanne." The works exhibited by these Cubists at the 1911 and 1912 Salons extended beyond the conventional Cezanne-like subjectsthe posed model, still-life and landscapefavored by Picasso and Braque to include large-scale modern-life subjects. Aimed at a large public, these works stressed the use of multiple perspective and complex planar faceting for expressive effect while preserving the eloquence of subjects endowed with literary and philosophical connotations.
Whom did Braque and Picasso not aim their works at?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The importance of infantry and light cavalry began to decline during the early Carolingian period, with a growing dominance of elite heavy cavalry. The use of militia-type levies of the free population declined over the Carolingian period. Although much of the Carolingian armies were mounted, a large proportion during the early period appear to have been mounted infantry, rather than true cavalry. One exception was Anglo-Saxon England, where the armies were still composed of regional levies, known as the fyrd, which were led by the local elites. In military technology, one of the main changes was the return of the crossbow, which had been known in Roman times and reappeared as a military weapon during the last part of the Early Middle Ages. Another change was the introduction of the stirrup, which increased the effectiveness of cavalry as shock troops. A technological advance that had implications beyond the military was the horseshoe, which allowed horses to be used in rocky terrain.
Along with light cavalry, what military arm declined in importance during the Early Middle Ages?
A: infantry

Context and question: Qutb Shahi architecture of the 16th and early 17th centuries followed classical Persian architecture featuring domes and colossal arches. The oldest surviving Qutb Shahi structure in Hyderabad is the ruins of Golconda fort built in the 16th century. The Charminar, Mecca Masjid, Charkaman and Qutb Shahi tombs are other existing structures of this period. Among these the Charminar has become an icon of the city; located in the centre of old Hyderabad, it is a square structure with sides 20 m (66 ft) long and four grand arches each facing a road. At each corner stands a 56 m (184 ft)-high minaret. Most of the historical bazaars that still exist were constructed on the street north of Charminar towards Golconda fort. The Charminar, Qutb Shahi tombs and Golconda fort are considered to be monuments of national importance in India; in 2010 the Indian government proposed that the sites be listed for UNESCO World Heritage status.:1118
What influence did Qutb Shahi architecture borrow from?
Answer: classical Persian architecture

Question: However, leeches and their closest relatives have a body structure that is very uniform within the group but significantly different from that of other annelids, including other members of the Clitellata. In leeches there are no septa, the connective tissue layer of the body wall is so thick that it occupies much of the body, and the two coelomata are widely separated and run the length of the body. They function as the main blood vessels, although they are side-by-side rather than upper and lower. However, they are lined with mesothelium, like the coelomata and unlike the blood vessels of other annelids. Leeches generally use suckers at their front and rear ends to move like inchworms. The anus is on the upper surface of the pygidium.
Is there an answer to this question: What do leeches use to fly?

Answer: unanswerable

The MoD states that its principal objectives are to defend the United Kingdom of Great Britain and Northern Ireland and its interests and to strengthen international peace and stability. With the collapse of the Soviet Union and the end of the Cold War, the MoD does not foresee any short-term conventional military threat; rather, it has identified weapons of mass destruction, international terrorism, and failed and failing states as the overriding threats to Britain's interests. The MoD also manages day-to-day running of the armed forces, contingency planning and defence procurement.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What has Northern Ireland found are threats to international peace and stability?
Ah, so..
