Problem: Hunter-gatherer:

Hunting-gathering was the common human mode of subsistence throughout the Paleolithic, but the observation of current-day hunters and gatherers does not necessarily reflect Paleolithic societies; the hunter-gatherer cultures examined today have had much contact with modern civilization and do not represent "pristine" conditions found in uncontacted peoples.

Where do you find groups that represent pristine conditions?
---
A: in uncontacted peoples


Problem: Breeding usually involves some form of courtship display, typically performed by the male. Most displays are rather simple and involve some type of song. Some displays, however, are quite elaborate. Depending on the species, these may include wing or tail drumming, dancing, aerial flights, or communal lekking. Females are generally the ones that drive partner selection, although in the polyandrous phalaropes, this is reversed: plainer males choose brightly coloured females. Courtship feeding, billing and allopreening are commonly performed between partners, generally after the birds have paired and mated.
Most courtship displays involve some type of what?

Answer: song


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Paris' manufacturing is mostly focused in its suburbs, and the city itself has only around 75,000 manufacturing workers, most of which are in the textile, clothing, leather goods and shoe trades. Paris region manufacturing specialises in transportation, mainly automobiles, aircraft and trains, but this is in a sharp decline: Paris proper manufacturing jobs dropped by 64 percent between 1990 and 2010, and the Paris region lost 48 percent during the same period. Most of this is due to companies relocating outside the Paris region. The Paris region's 800 aerospace companies employed 100,000. Four hundred automobile industry companies employ another 100,000 workers: many of these are centred in the Yvelines department around the Renault and PSA-Citroen plants (this department alone employs 33,000), but the industry as a whole suffered a major loss with the 2014 closing of a major Aulnay-sous-Bois Citroen assembly plant.
How many manufacturing workers does Paris have?
A: 75,000

Question: The Recommended Exposure Index (REI) technique, new in the 2006 version of the standard, allows the manufacturer to specify a camera model’s EI choices arbitrarily. The choices are based solely on the manufacturer’s opinion of what EI values produce well-exposed sRGB images at the various sensor sensitivity settings. This is the only technique available under the standard for output formats that are not in the sRGB color space. This is also the only technique available under the standard when multi-zone metering (also called pattern metering) is used.
Is there an answer to this question: What is another name for multi-zone metering?

Answer: pattern metering


Question: Historical studies reveal that policing agents have undertaken a variety of cross-border police missions for many years (Deflem, 2002). For example, in the 19th century a number of European policing agencies undertook cross-border surveillance because of concerns about anarchist agitators and other political radicals. A notable example of this was the occasional surveillance by Prussian police of Karl Marx during the years he remained resident in London. The interests of public police agencies in cross-border co-operation in the control of political radicalism and ordinary law crime were primarily initiated in Europe, which eventually led to the establishment of Interpol before the Second World War. There are also many interesting examples of cross-border policing under private auspices and by municipal police forces that date back to the 19th century (Nadelmann, 1993). It has been established that modern policing has transgressed national boundaries from time to time almost from its inception. It is also generally agreed that in the post–Cold War era this type of practice became more significant and frequent (Sheptycki, 2000).
Is there an answer to this question: What groups did European police work against across borders in the 19th century?

Answer:
anarchist agitators and other political radicals
