Here is a question about this article: The Somerset Levels (or Somerset Levels and Moors as they are less commonly but more correctly known) are a sparsely populated wetland area of central Somerset, between the Quantock and Mendip hills. They consist of marine clay levels along the coast, and the inland (often peat based) moors. The Levels are divided into two by the Polden Hills; land to the south is drained by the River Parrett while land to the north is drained by the River Axe and the River Brue. The total area of the Levels amounts to about 647.5 square kilometres (160,000 acres) and broadly corresponds to the administrative district of Sedgemoor but also includes the south west of Mendip district. Approximately 70% of the area is grassland and 30% is arable. Stretching about 32 kilometres (20 mi) inland, this expanse of flat land barely rises above sea level. Before it was drained, much of the land was under a shallow brackish sea in winter and was marsh land in summer. Drainage began with the Romans, and was restarted at various times: by the Anglo-Saxons; in the Middle Ages by the Glastonbury Abbey, from 1400–1770; and during the Second World War, with the construction of the Huntspill River. Pumping and management of water levels still continues.
What is the answer to this question: who started drainage of the Somerset levels 
****
So... the Romans, and was restarted at various times: by the Anglo-Saxons


Here is a question about this article: As a side effect of the electrochemical processes used by neurons for signaling, brain tissue generates electric fields when it is active. When large numbers of neurons show synchronized activity, the electric fields that they generate can be large enough to detect outside the skull, using electroencephalography (EEG) or magnetoencephalography (MEG). EEG recordings, along with recordings made from electrodes implanted inside the brains of animals such as rats, show that the brain of a living animal is constantly active, even during sleep. Each part of the brain shows a mixture of rhythmic and nonrhythmic activity, which may vary according to behavioral state. In mammals, the cerebral cortex tends to show large slow delta waves during sleep, faster alpha waves when the animal is awake but inattentive, and chaotic-looking irregular activity when the animal is actively engaged in a task. During an epileptic seizure, the brain's inhibitory control mechanisms fail to function and electrical activity rises to pathological levels, producing EEG traces that show large wave and spike patterns not seen in a healthy brain. Relating these population-level patterns to the computational functions of individual neurons is a major focus of current research in neurophysiology.
What is the answer to this question: What type of brain waves are seen in mammals during sleep?
****
So... large slow delta waves


Here is a question about this article: Most historians today, including John's recent biographers Ralph Turner and Lewis Warren, argue that John was an unsuccessful monarch, but note that his failings were exaggerated by 12th- and 13th-century chroniclers. Jim Bradbury notes the current consensus that John was a "hard-working administrator, an able man, an able general", albeit, as Turner suggests, with "distasteful, even dangerous personality traits", including pettiness, spitefulness and cruelty. John Gillingham, author of a major biography of Richard I, follows this line too, although he considers John a less effective general than do Turner or Warren, and describes him "one of the worst kings ever to rule England". Bradbury takes a moderate line, but suggests that in recent years modern historians have been overly lenient towards John's numerous faults. Popular historian Frank McLynn maintains a counter-revisionist perspective on John, arguing that the king's modern reputation amongst historians is "bizarre", and that as a monarch John "fails almost all those [tests] that can be legitimately set".
