Problem: The Blitz:

The Boulton Paul Defiant, despite its poor performance during daylight engagements, was a much better night fighter. It was faster, able to catch the bombers and its configuration of four machine guns in a turret could (much like German night fighters in 1943–1945 with Schräge Musik) engage the unsuspecting German bomber from beneath. Attacks from below offered a larger target, compared to attacking tail-on, as well as a better chance of not being seen by the bomber (so less chance of evasion), as well as greater likelihood of detonating its bombload. In subsequent months a steady number of German bombers would fall to night fighters.

What performed better during night fighting?

A: The Boulton Paul Defiant


Problem: In many societies, however, a particular dialect, often the sociolect of the elite class, comes to be identified as the "standard" or "proper" version of a language by those seeking to make a social distinction, and is contrasted with other varieties. As a result of this, in some contexts the term "dialect" refers specifically to varieties with low social status. In this secondary sense of "dialect", language varieties are often called dialects rather than languages:
What social status is the term "dialect" sometimes associated with?

Zhejiang's main manufacturing sectors are electromechanical industries, textiles, chemical industries, food, and construction materials. In recent years Zhejiang has followed its own development model, dubbed the "Zhejiang model", which is based on prioritizing and encouraging entrepreneurship, an emphasis on small businesses responsive to the whims of the market, large public investments into infrastructure, and the production of low-cost goods in bulk for both domestic consumption and export. As a result, Zhejiang has made itself one of the richest provinces, and the "Zhejiang spirit" has become something of a legend within China. However, some economists now worry that this model is not sustainable, in that it is inefficient and places unreasonable demands on raw materials and public utilities, and also a dead end, in that the myriad small businesses in Zhejiang producing cheap goods in bulk are unable to move to more sophisticated or technologically more advanced industries. The economic heart of Zhejiang is moving from North Zhejiang, centered on Hangzhou, southeastward to the region centered on Wenzhou and Taizhou. The per capita disposable income of urbanites in Zhejiang reached 24,611 yuan (US$3,603) in 2009, an annual real growth of 8.3%. The per capita pure income of rural residents stood at 10,007 yuan (US$1,465), a real growth of 8.1% year-on-year. Zhejiang's nominal GDP for 2011 was 3.20 trillion yuan (US$506 billion) with a per capita GDP of 44,335 yuan (US$6,490). In 2009, Zhejiang's primary, secondary, and tertiary industries were worth 116.2 billion yuan (US$17 billion), 1.1843 trillion yuan (US$173.4 billion), and 982.7 billion yuan (US$143.9 billion) respectively.
 What direction is the economic heart of Zhejiang moving away from?
A: unanswerable


Context and question: Philips' preferred name for the format was "VLP", after the Dutch words Video Langspeel-Plaat ("Video long-play disc"), which in English-speaking countries stood for Video Long-Play. The first consumer player, the Magnavox VH-8000 even had the VLP logo on the player. For a while in the early and mid-1970s, Philips also discussed a compatible audio-only format they called "ALP", but that was soon dropped as the Compact Disc system became a non-compatible project in the Philips corporation. Until early 1980, the format had no "official" name. The LaserVision Association, made up of MCA, Universal-Pioneer, IBM, and Philips/Magnavox, was formed to standardize the technical specifications of the format (which had been causing problems for the consumer market) and finally named the system officially as "LaserVision".
Which group officially chose the name "Laservision"?
Answer: The LaserVision Association

Karl Marx published the Communist Manifesto in February 1848, with little attention. However, a few days later the French Revolution of 1848 broke out, which replaced the monarchy of Louis Philippe with the Second French Republic. In June 1848, Paris workers, disenchanted with the new government, built barricades and raised red flags. The new government called in the French Army to put down the uprising, the first of many such confrontations between the army and the new worker's movements in Europe.
Who published the Communist Manifesto in 1884?
