Problem: Conventional bleaching of wood pulp using elemental chlorine produces and releases into the environment large amounts of chlorinated organic compounds, including chlorinated dioxins. Dioxins are recognized as a persistent environmental pollutant, regulated internationally by the Stockholm Convention on Persistent Organic Pollutants. Dioxins are highly toxic, and health effects on humans include reproductive, developmental, immune and hormonal problems. They are known to be carcinogenic. Over 90% of human exposure is through food, primarily meat, dairy, fish and shellfish, as dioxins accumulate in the food chain in the fatty tissue of animals.
Which agency nationally regulates dioxins?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The term also has closely related synonyms that are employed throughout the Quran. Each synonym possesses its own distinct meaning, but its use may converge with that of qur'an in certain contexts. Such terms include kitab (book); ayah (sign); and surah (scripture). The latter two terms also denote units of revelation. In the large majority of contexts, usually with a definite article (al-), the word is referred to as the "revelation" (wahy), that which has been "sent down" (tanzil) at intervals. Other related words are: dhikr (remembrance), used to refer to the Quran in the sense of a reminder and warning, and hikmah (wisdom), sometimes referring to the revelation or part of it.
What name doesn't the Quran use for itself that means "revelation"?
A: unanswerable

Context and question: In past times, mending was an art. A meticulous tailor or seamstress could mend rips with thread raveled from hems and seam edges so skillfully that the tear was practically invisible. When the raw material cloth was worth more than labor, it made sense to expend labor in saving it. Today clothing is considered a consumable item. Mass-manufactured clothing is less expensive than the labor required to repair it. Many people buy a new piece of clothing rather than spend time mending. The thrifty still replace zippers and buttons and sew up ripped hems.
What type of person is likely to replace zippers and buttons?
Answer: thrifty

Question: The interior of Galicia is characterized by its hilly landscape, although mountain ranges rise to 2,000 m (6,600 ft) in the east and south. The coastal areas are mostly an alternate series of rias (submerged valleys where the sea penetrates tens of kilometres inland) and cliffs. The climate of Galicia is temperate and rainy, but it is also markedly drier in the summer, being usually classified as Oceanic in the west and north, and Mediterranean in the southeast. Its topographic and climatic conditions have made animal husbandry and farming the primary source of Galicia's wealth for most of its history. With the exception of shipbuilding and food processing, Galicia was largely a semi-subsistence farming and fishing economy and did not experience significant industrialization until after the mid-20th century. In 2012, the gross domestic product at purchasing power parity was 56,000 million, with a nominal GDP per capita of 20,700. The population is largely concentrated in two coastal areas: from Ferrol to A Coruna in the northwest and from Pontevedra to Vigo in the southwest. To a lesser extent, there are smaller populations around the interior cities of Lugo, Ourense and Santiago de Compostela. The political capital is Santiago de Compostela, in the province of A Coruna. Vigo, in the province of Pontevedra, is the most populous municipality with 294,997 (2014), while A Coruna is the most populous city with 215.227 (2014).
Is there an answer to this question: Name its northwestern coastal area.

Answer: Ferrol to A Coruna

A major feature is the calypso competition. Calypso music, originating in Trinidad, uses syncopated rhythm and topical lyrics. It offers a medium in which to satirise local politics, amidst the general bacchanal. Calypso tents, also originating in Trinidad, feature cadres of musicians who perform biting social commentaries, political exposes or rousing exhortations to "wuk dah waistline" and "roll dat bumper". The groups compete for the Calypso Monarch Award, while the air is redolent with the smells of Bajan cooking during the Bridgetown Market Street Fair. The Cohobblopot Festival blends dance, drama and music with the crowning of the King and Queen of costume bands. Every evening the "Pic-o-de-Crop" Show is performed after the King of Calypso is finally crowned. The climax of the festival is Kadooment Day celebrated with a national holiday when costume bands fill the streets with pulsating Barbadian rhythms and fireworks.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What do the musical groups compete for?
Ah, so..
the Calypso Monarch Award
