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.
 Where are dioxins expelled in our animal sources of food?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the 19th century, southern and central European sport hunters often pursued game only for a trophy, usually the head or pelt of an animal, which was then displayed as a sign of prowess. The rest of the animal was typically discarded. Some cultures, however, disapprove of such waste. In Nordic countries, hunting for trophies was—and still is—frowned upon. Hunting in North America in the 19th century was done primarily as a way to supplement food supplies, although it is now undertaken mainly for sport.[citation needed] The safari method of hunting was a development of sport hunting that saw elaborate travel in Africa, India and other places in pursuit of trophies. In modern times, trophy hunting persists and is a significant industry in some areas.[citation needed]
What did North America primarily hunt for?
A: food supplies


Context and question: The early Christian philosophy of Augustine of Hippo was heavily influenced by Plato. A key change brought about by Christian thought was the moderatation of the Stoicism and theory of justice of the Roman world, as well emphasis on the role of the state in applying mercy as a moral example. Augustine also preached that one was not a member of his or her city, but was either a citizen of the City of God (Civitas Dei) or the City of Man (Civitas Terrena). Augustine's City of God is an influential work of this period that attacked the thesis, held by many Christian Romans, that the Christian view could be realized on Earth.
Who influenced Terrena's view of the moderation of the Stoicism?

Question: Classified as a Subtropical Mediterranean climate (Köppen Csb), Santa Monica enjoys an average of 310 days of sunshine a year. It is located in USDA plant hardiness zone 11a. Because of its location, nestled on the vast and open Santa Monica Bay, morning fog is a common phenomenon in May, June and early July (caused by ocean temperature variations and currents). Like other inhabitants of the greater Los Angeles area, residents have a particular terminology for this phenomenon: the "May Gray" and the "June Gloom". Overcast skies are common during June mornings, but usually the strong sun burns the fog off by noon. In the late winter/early summer, daily fog is a phenomenon too. It happens suddenly and it may last some hours or past sunset time. Nonetheless, it will sometimes stay cloudy and cool all day during June, even as other parts of the Los Angeles area enjoy sunny skies and warmer temperatures. At times, the sun can be shining east of 20th Street, while the beach area is overcast. As a general rule, the beach temperature is from 5 to 10 degrees Fahrenheit (3 to 6 degrees Celsius) cooler than it is inland during summer days, and 5–10 degrees warmer during winter nights.
Is there an answer to this question: What the average temperature in winter in fahrenheit?

Answer: unanswerable
