Problem: The Dominican Order came into being in the Middle Ages at a time when religion began to be contemplated in a new way. Men of God were no longer expected to stay behind the walls of a cloister. Instead, they travelled among the people, taking as their examples the apostles of the primitive Church. Out of this ideal emerged two orders of mendicant friars: one, the Friars Minor, was led by Francis of Assisi; the other, the Friars Preachers, by Dominic of Guzman. Like his contemporary, Francis, Dominic saw the need for a new type of organization, and the quick growth of the Dominicans and Franciscans during their first century of existence confirms that the orders of mendicant friars met a need.
Who led the Friars Major order at this time?

One method to obtain information on the oldest core of Buddhism is to compare the oldest extant versions of the Theravadin Pali Canon and other texts.[note 27] The reliability of these sources, and the possibility to draw out a core of oldest teachings, is a matter of dispute.[page needed][page needed][page needed][page needed] According to Vetter, inconsistencies remain, and other methods must be applied to resolve those inconsistencies.[note 28]

Question: Sleep involves great changes in brain activity. Until the 1950s it was generally believed that the brain essentially shuts off during sleep, but this is now known to be far from true; activity continues, but patterns become very different. There are two types of sleep: REM sleep (with dreaming) and NREM (non-REM, usually without dreaming) sleep, which repeat in slightly varying patterns throughout a sleep episode. Three broad types of distinct brain activity patterns can be measured: REM, light NREM and deep NREM. During deep NREM sleep, also called slow wave sleep, activity in the cortex takes the form of large synchronized waves, whereas in the waking state it is noisy and desynchronized. Levels of the neurotransmitters norepinephrine and serotonin drop during slow wave sleep, and fall almost to zero during REM sleep; levels of acetylcholine show the reverse pattern.
Is there an answer to this question: During what stage of sleep do serotonin and norepinephrine levels drop?

Answer: slow wave sleep

On ancient reliefs, especially from Mesopotamia, kings are often depicted as hunters of big game such as lions and are often portrayed hunting from a war chariot. The cultural and psychological importance of hunting in ancient societies is represented by deities such as the horned god Cernunnos and lunar goddesses of classical antiquity, the Greek Artemis or Roman Diana. Taboos are often related to hunting, and mythological association of prey species with a divinity could be reflected in hunting restrictions such as a reserve surrounding a temple. Euripides' tale of Artemis and Actaeon, for example, may be seen as a caution against disrespect of prey or impudent boasting.
