Input: Article: Nigeria is home to a substantial network of organised crime, active especially in drug trafficking. Nigerian criminal groups are heavily involved in drug trafficking, shipping heroin from Asian countries to Europe and America; and cocaine from South America to Europe and South Africa. . The various Nigerian Confraternities or "campus cults" are active in both organised crime and in political violence as well as providing a network of corruption within Nigeria. As confraternities have extensive connections with political and military figures, they offer excellent alumni networking opportunities. The Supreme Vikings Confraternity, for example, boasts that twelve members of the Rivers State House of Assembly are cult members. On lower levels of society, there are the "area boys", organised gangs mostly active in Lagos who specialise in mugging and small-scale drug dealing. According to official statistics, gang violence in Lagos resulted in 273 civilians and 84 policemen killed in the period of August 2000 to May 2001.

Now answer this question: How many police were killed in Lagos in Aug 2000-May 2001?

Output: 84

Article: In 1991, there were only two proposals available that could be completely assessed for an MPEG audio standard: Musicam (Masking pattern adapted Universal Subband Integrated Coding And Multiplexing) and ASPEC (Adaptive Spectral Perceptual Entropy Coding). The Musicam technique, as proposed by Philips (the Netherlands), CCETT (France) and Institut fur Rundfunktechnik (Germany) was chosen due to its simplicity and error robustness, as well as its low computational power associated with the encoding of high quality compressed audio. The Musicam format, based on sub-band coding, was the basis of the MPEG Audio compression format (sampling rates, structure of frames, headers, number of samples per frame).

Question: Which other quality alongside simplicty was key in selecting this proposal?
Ans: error robustness

Here is a question about this article: Industry is diversified, ranging from automotive (Volkswagen Autoeuropa and Peugeot Citroen), aerospace (Embraer and OGMA), electronics and textiles, to food, chemicals, cement and wood pulp. Volkswagen Group's AutoEuropa motor vehicle assembly plant in Palmela is among the largest foreign direct investment projects in Portugal. Modern non-traditional technology-based industries, such as aerospace, biotechnology and information technology, have been developed in several locations across the country. Alverca, Covilha, Evora, and Ponte de Sor are the main centres of the Portuguese aerospace industry, which is led by Brazil-based company Embraer and the Portuguese company OGMA. Following the turn of the 21st century, many major biotechnology and information technology industries have been founded, and are concentrated in the metropolitan areas of Lisbon, Porto, Braga, Coimbra and Aveiro.[citation needed]
What is the answer to this question: What automotive brands exist in Portugal?
****
So... Volkswagen Autoeuropa and Peugeot Citroen

The problem: Answer a question about this article:
Panama's first department stores such as Bazaar Frances, La Dalia and La Villa de Paris started as textile retailers at the turn of the nineteenth century. Later on in the twentieth century these eventually gave way to stores such as Felix B. Maduro, Sarah Panama, Figali, Dante, Sears, Gran Morrison and smaller ones such as Bon Bini, Cocos, El Lider, Piccolo and Clubman among others. Of these only Felix B. Maduro (usually referred to as Felix by locals) and Dante remain strong. All the others have either folded or declined although Cocos has managed to secure a good position in the market.
What department store is often called "Felix" by the local population?
****
The answer: Felix B. Maduro

Problem: Please answer a question about the following article about Copper:
The metal's distinctive natural green patina has long been coveted by architects and designers. The final patina is a particularly durable layer that is highly resistant to atmospheric corrosion, thereby protecting the underlying metal against further weathering. It can be a mixture of carbonate and sulfate compounds in various amounts, depending upon environmental conditions such as sulfur-containing acid rain. Architectural copper and its alloys can also be 'finished' to embark a particular look, feel, and/or color. Finishes include mechanical surface treatments, chemical coloring, and coatings.
What mixture of compounds is the final patina?
A: carbonate and sulfate

Question: Read this and answer the question

Captain John Byron passed through the islands of Tuvalu in 1764 during his circumnavigation of the globe as captain of the Dolphin (1751). Byron charted the atolls as Lagoon Islands. Keith S. Chambers and Doug Munro (1980) identified Niutao as the island that Francisco Mourelle de la Rua sailed past on 5 May 1781, thus solving what Europeans had called The Mystery of Gran Cocal. Mourelle's map and journal named the island El Gran Cocal ('The Great Coconut Plantation'); however, the latitude and longitude was uncertain. Longitude could only be reckoned crudely as accurate chronometers were unavailable until the late 18th century.

What explorer traveled through the Tuvalu islands in 1764?
Answer:
Captain John Byron
