Problem: Athanasius of Alexandria:

Conflict with Arius and Arianism as well as successive Roman emperors shaped Athanasius's career. In 325, at the age of 27, Athanasius began his leading role against the Arians as his bishop's assistant during the First Council of Nicaea. Roman emperor Constantine the Great had convened the council in MayAugust 325 to address the Arian position that the Son of God, Jesus of Nazareth, is of a distinct substance from the Father. Three years after that council, Athanasius succeeded his mentor as archbishop of Alexandria. In addition to the conflict with the Arians (including powerful and influential Arian churchmen led by Eusebius of Nicomedia), he struggled against the Emperors Constantine, Constantius II, Julian the Apostate and Valens. He was known as "Athanasius Contra Mundum" (Latin for Athanasius Against the World).

Problem: Old English nouns had grammatical gender, a feature absent in modern English, which uses only natural gender. For example, the words sunne ("sun"), mona ("moon") and wif ("woman/wife") were respectively feminine, masculine and neuter; this is reflected, among other things, in the form of the definite article used with these nouns: seo sunne ("the sun"), se mona ("the moon"), t wif ("the woman/wife"). Pronoun usage could reflect either natural or grammatical gender, when those conflicted (as in the case of wif, a neuter noun referring to a female person).
What type of gender did Old English nouns possess?

Question: A person can be exposed to uranium (or its radioactive daughters, such as radon) by inhaling dust in air or by ingesting contaminated water and food. The amount of uranium in air is usually very small; however, people who work in factories that process phosphate fertilizers, live near government facilities that made or tested nuclear weapons, live or work near a modern battlefield where depleted uranium weapons have been used, or live or work near a coal-fired power plant, facilities that mine or process uranium ore, or enrich uranium for reactor fuel, may have increased exposure to uranium. Houses or structures that are over uranium deposits (either natural or man-made slag deposits) may have an increased incidence of exposure to radon gas. The Occupational Safety and Health Administration (OSHA) has set the permissible exposure limit for uranium exposure in the workplace as 0.25 mg/m3 over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 0.2 mg/m3 over an 8-hour workday and a short-term limit of 0.6 mg/m3. At levels of 10 mg/m3, uranium is immediately dangerous to life and health.

The King presides over a period of misrule in which conventional social rules may be broken and reckless behavior is encouraged. Festivities are held in the open air, beginning with a cercavila, a ritual procession throughout the town to call everyone to attend. Rues of masked revelers dance alongside. On Thursday Dijous Gras (Fat Thursday) is celebrated, also called 'omelette day' (el dia de la truita), coques (de llardons, butifarra d'ou, butifarra) and omelettes are eaten. The festivities end on Ash Wednesday with elaborate funeral rituals marking the death of King Carnival, who is typically burned on a pyre in what is called the burial of the sardine (enterrament de la sardina), or, in Vilanova, as l'enterro.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who is typically burned on a pyre?

King Carnival
