neurons talk each other through, Context: The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead. The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

What benefits outside the show do the high end sponsors enjoy?, Context: The dominance of American Idol in the ratings had made it the most profitable show in U.S. TV for many years. The show was estimated to generate $900 million for the year 2004 through sales of TV ads, albums, merchandise and concert tickets. By season seven, the show was estimated to earn around $900 million from its ad revenue alone, not including ancillary sponsorship deals and other income. One estimate puts the total TV revenue for the first eight seasons of American at $6.4 billion. Sponsors that bought fully integrated packages can expect a variety of promotions of their products on the show, such as product placement, adverts and product promotion integrated into the show, and various promotional opportunities. Other off-air promotional partners pay for the rights to feature "Idol" branding on their packaging, products and marketing programs. American Idol also partnered with Disney in its theme park attraction The American Idol Experience.

Where has London yet to be classified as a capital city in the UK?, Context: Within London, both the City of London and the City of Westminster have city status and both the City of London and the remainder of Greater London are counties for the purposes of lieutenancies. The area of Greater London has incorporated areas that were once part of the historic counties of Middlesex, Kent, Surrey, Essex and Hertfordshire. London's status as the capital of England, and later the United Kingdom, has never been granted or confirmed officially—by statute or in written form.[note 6]
