Problem: Modern history:

After the early 20th century revolutions, shifting alliances of China's regional warlords waged war for control of the Beijing government. Despite the fact that various warlords gained control of the government in Beijing during the warlord era, this did not constitute a new era of control or governance, because other warlords did not acknowledge the transitory governments in this period and were a law unto themselves. These military-dominated governments were collectively known as the Beiyang government. The warlord era ended around 1927.

When did the warlord era end?
---
A: around 1927


Problem: A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover from the Devonian or not. These conditions apparently had little effect in the deep tropics, where lush coal swamps flourished within 30 degrees of the northernmost glaciers. A mid-Carboniferous drop in sea-level precipitated a major marine extinction, one that hit crinoids and ammonites especially hard. This sea-level drop and the associated unconformity in North America separate the Mississippian Period from the Pennsylvanian period.

Emulation of the SNES is now available on handheld units, such as Android devices, Apple's iPhone and iPad, Sony's PlayStation Portable (PSP), the Nintendo DS and Game Boy Advance, the Gizmondo, the Dingoo and the GP2X by GamePark Holdings, as well as PDAs. While individual games have been included with emulators on some GameCube discs, Nintendo's Virtual Console service for the Wii marks the introduction of officially sanctioned general SNES emulation, though SNES9x GX, a port of SNES9x, has been made for the Wii.
What portable game systems have SNES emulators?
A: Sony's PlayStation Portable (PSP), the Nintendo DS and Game Boy Advance, the Gizmondo, the Dingoo and the GP2X by GamePark Holdings


Context and question: London's defences were rapidly reorganised by General Pile, the Commander-in-Chief of Anti-Aircraft Command. The difference this made to the effectiveness of air defences is questionable. The British were still one-third below the establishment of heavy anti-aircraft artillery AAA (or ack-ack) in May 1941, with only 2,631 weapons available. Dowding had to rely on night fighters. From 1940 to 1941, the most successful night-fighter was the Boulton Paul Defiant; its four squadrons shot down more enemy aircraft than any other type. AA defences improved by better use of radar and searchlights. Over several months, the 20,000 shells spent per raider shot down in September 1940, was reduced to 4,087 in January 1941 and to 2,963 shells in February 1941.
Who's four squadrons shot down more enemy aircraft than any other type?
Answer: Boulton Paul Defiant


Question: Tibetan sources say Deshin Shekpa also persuaded the Yongle Emperor not to impose his military might on Tibet as the Mongols had previously done. Thinley writes that before the Karmapa returned to Tibet, the Yongle Emperor began planning to send a military force into Tibet to forcibly give the Karmapa authority over all the Tibetan Buddhist schools but Deshin Shekpa dissuaded him. However, Hok-Lam Chan states that "there is little evidence that this was ever the emperor's intention" and that evidence indicates that Deshin Skekpa was invited strictly for religious purposes.
Is there an answer to this question: What was said to be the  Yongle Emperor plans?

Answer: to send a military force into Tibet

One of the common definitions for "Islamic philosophy" is "the style of philosophy produced within the framework of Islamic culture." Islamic philosophy, in this definition is neither necessarily concerned with religious issues, nor is exclusively produced by Muslims. The Persian scholar Ibn Sina (Avicenna) (980–1037) had more than 450 books attributed to him. His writings were concerned with various subjects, most notably philosophy and medicine. His medical textbook The Canon of Medicine was used as the standard text in European universities for centuries. He also wrote The Book of Healing, an influential scientific and philosophical encyclopedia.
What philosophy is strictly produced by Muslims?
A:
unanswerable
