Problem: Catalan language:

The same happens with Arabic loanwords. Thus, Catalan alfàbia "large earthenware jar" and rajola "tile", of Arabic origin, contrast with Spanish tinaja and teja, of Latin origin; whereas Catalan oli "oil" and oliva "olive", of Latin origin, contrast with Spanish aceite and aceituna. However, the Arabic element in Spanish is generally much more prevalent.

What is the origin of the Spanish word teja?

A: Latin origin


Problem: Carnival Tuesday hosts the main events. Full costume is worn, complete with make-up and body paint/adornment. Usually "Mas Boots" that complement the costumes are worn. Each band has their costume presentation based on a particular theme, and contains various sections (some consisting of thousands of revelers) that reflect these themes. The street parade and band costume competition take place. The mas bands eventually converge on the Queen's Park Savannah to pass on "The Stage" for judging. The singer of the most played song is crowned Road March King or Queen earning prize money and usually a vehicle.
Who gets to be crowned Road March King or Queen?
---
Answer: The singer of the most played song


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
"Green" in modern European languages corresponds to about 520–570 nm, but many historical and non-European languages make other choices, e.g. using a term for the range of ca. 450–530 nm ("blue/green") and another for ca. 530–590 nm ("green/yellow").[citation needed] In the comparative study of color terms in the world's languages, green is only found as a separate category in languages with the fully developed range of six colors (white, black, red, green, yellow, and blue), or more rarely in systems with five colors (white, red, yellow, green, and black/blue). (See distinction of green from blue) These languages have introduced supplementary vocabulary to denote "green", but these terms are recognizable as recent adoptions that are not in origin color terms (much like the English adjective orange being in origin not a color term but the name of a fruit). Thus, the Thai word เขียว besides meaning "green" also means "rank" and "smelly" and holds other unpleasant associations.
In which language does the word for "green" also mean "rank" and "smelly"?
A: Thai


Context and question: Chapter IV details natural selection under the "infinitely complex and close-fitting ... mutual relations of all organic beings to each other and to their physical conditions of life". Darwin takes as an example a country where a change in conditions led to extinction of some species, immigration of others and, where suitable variations occurred, descendants of some species became adapted to new conditions. He remarks that the artificial selection practised by animal breeders frequently produced sharp divergence in character between breeds, and suggests that natural selection might do the same, saying:
What did Darwin say could happen somewhere if there is a change in conditions?
Answer: extinction of some species


Question: On an international level the German DIN 4512 system has been effectively superseded in the 1980s by ISO 6:1974, ISO 2240:1982, and ISO 5800:1979 where the same sensitivity is written in linear and logarithmic form as "ISO 100/21°" (now again with degree symbol). These ISO standards were subsequently adopted by DIN as well. Finally, the latest DIN 4512 revisions were replaced by corresponding ISO standards, DIN 4512-1:1993-05 by DIN ISO 6:1996-02 in September 2000, DIN 4512-4:1985-08 by DIN ISO 2240:1998-06 and DIN 4512-5:1990-11 by DIN ISO 5800:1998-06 both in July 2002.
Is there an answer to this question: What standards did the DIN begin to use?

Answer: ISO standards


QUES: The history of emotions has become an increasingly popular topic recently, with some scholars arguing that it is an essential category of analysis, not unlike class, race, or gender. Historians, like other social scientists, assume that emotions, feelings and their expressions are regulated in different ways by both different cultures and different historical times, and constructivist school of history claims even that some sentiments and meta-emotions, for example Schadenfreude, are learnt and not only regulated by culture. Historians of emotion trace and analyse the changing norms and rules of feeling, while examining emotional regimes, codes, and lexicons from social, cultural or political history perspectives. Others focus on the history of medicine, science or psychology. What somebody can and may feel (and show) in a given situation, towards certain people or things, depends on social norms and rules. It is thus historically variable and open to change. Several research centers have opened in the past few years in Germany, England, Spain, Sweden and Australia.

Along with Germany, England, Spain and Australia, where hasn't a research center on the history of emotions recently opened?
