Please answer this: This article: Whales are known to teach, learn, cooperate, scheme, and grieve. The neocortex of many species of whale is home to elongated spindle neurons that, prior to 2007, were known only in hominids. In humans, these cells are involved in social conduct, emotions, judgement, and theory of mind. Whale spindle neurons are found in areas of the brain that are homologous to where they are found in humans, suggesting that they perform a similar function. Brain size was previously considered a major indicator of the intelligence of an animal. Since most of the brain is used for maintaining bodily functions, greater ratios of brain to body mass may increase the amount of brain mass available for more complex cognitive tasks. Allometric analysis indicates that mammalian brain size scales at approximately the or exponent of the body mass. Comparison of a particular animal's brain size with the expected brain size based on such allometric analysis provides an encephalisation quotient that can be used as another indication of animal intelligence. Sperm whales have the largest brain mass of any animal on earth, averaging 8,000 cubic centimetres (490 in3) and 7.8 kilograms (17 lb) in mature males, in comparison to the average human brain which averages 1,450 cubic centimetres (88 in3) in mature males. The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans.Small whales are known to engage in complex play behaviour, which includes such things as producing stable underwater toroidal air-core vortex rings or "bubble rings". There are two main methods of bubble ring production: rapid puffing of a burst of air into the water and allowing it to rise to the surface, forming a ring, or swimming repeatedly in a circle and then stopping to inject air into the helical vortex currents thus formed. They also appear to enjoy biting the vortex-rings, so that they burst into many separate bubbles and then rise quickly to the surface. Some believe this is a means of communication. Whales are... contains an answer for the question: What two types of odontocetes has a brain to body mass second only to humans?, what is it ?

Answer: belugas

Problem: This article: Amidst mourning with her family, she focused on work to deal with the grief, avoiding any news coverage of her sibling's death. She commented, "it's still important to face reality, and not that I'm running, but sometimes you just need to get away for a second." During this time, she ended her seven-year relationship with Jermaine Dupri.Several months later, Jackson performed a tribute to Michael at the 2009 MTV Video Music Awards, performing their duet "Scream". MTV stated "there was no one better than Janet to anchor it and send a really powerful message." The performance was lauded by critics, with Entertainment Weekly affirming the rendition "as energetic as it was heartfelt".Jackson's second hits compilation, Number Ones (retitled The Best for international releases), was released in November 2009. For promotion, she performed a medley of hits at the American Music Awards, Capital FM's Jingle Bell Ball at London's O2 arena, and The X-Factor. The album's promotional single "Make Me", produced with Rodney "Darkchild" Jerkins, debuted in September. It became Jackson's nineteenth number one on the Hot Dance Club Songs chart, making her the first artist to have number-one singles in four separate decades.Later that month, Jackson chaired the inaugural benefit of amfAR, The Foundation for AIDS Research, held in Milan in conjunction with fashion week. The foundation's CEO stated "We are profoundly grateful to Janet Jackson for joining amfAR as a chair of its first event in Milan.... She brings incomparable grace and a history of dedication to the fight against AIDS." The event raised a total of $1.1 million for the nonprofit organization. contains an answer for the question: What is the full name of the first artist to have number-one singles in four separate decades?, what is it ?

A: Janet Jackson

Q: This article: Edmund Sharpe was born on 31 October 1809 at Brook Cottage, Brook Street in Knutsford, Cheshire, the first child of Francis and Martha Sharpe. His father, a peripatetic music teacher and organist at Knutsford parish church, came from Stamford in Lincolnshire. At the time of marriage his wife, Martha Whittaker, was on the staff of an academy for young ladies, Belvedere House, in Bath, Somerset. During his childhood in Knutsford, the young Edmund played with Elizabeth Stevenson, the future Mrs Gaskell. In 1812 the Sharpe family moved across town from Over Knutsford to a farm in Nether Knutsford called Heathside, when Francis Sharpe then worked as both farmer and music teacher. Edmund was initially educated by his parents, but by 1818 he was attending a school in Knutsford. Two years later he was a boarder at a school near Runcorn, and in 1821 at Burney's Academy in Greenwich. Edmund's father died suddenly in November 1823, aged 48, and his mother moved to Lancaster with her family, where she later resumed her teaching career.Edmund continued his education at Burney's Academy, and became head boy. In August 1827 he moved to Sedbergh School (then in the West Riding of Yorkshire, now in Cumbria), where he remained for two years. In November 1829 he entered St John's College, Cambridge as a Lupton scholar. At the end of his course in 1832 he was awarded a Worts Travelling Bachelorship by the University of Cambridge, which enabled him to travel abroad for three years' study. At this time his friend from Lancaster at Trinity College, William Whewell, was Professor of Mineralogy. John Hughes, Edmund Sharpe's biographer, is of the opinion that Whewell was influential in gaining this award for Sharpe. Edmund graduated BA in 1833, and was admitted to the degree of MA in 1836. During his time abroad he travelled in Germany and southern France, studying Romanesque and early Gothic architecture. He had intended to travel further into northern France, but his tour was curtailed in Paris owing to "fatigue and illness".... contains an answer for the question: What is the full name of the person who was attending a school in Knutsford by 1818?, what is it ?

Edmund Sharpe
