Please answer the following question: Information: - London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly. - Sir William Crookes (17 June 1832 4 April 1919) was an English chemist and physicist who attended the Royal College of Chemistry, London, and worked on spectroscopy. He was a pioneer of vacuum tubes, inventing the Crookes tube which was made in 1875. Crookes was the inventor of the Crookes radiometer, which today is made and sold as a novelty item. Late in life, he became interested in spiritualism, and became the president of the Society for Psychical Research. - The Society for Psychical Research (SPR) is a non-profit organisation in the United Kingdom. Its stated purpose is to understand events and abilities commonly described as psychic or paranormal. It describes itself as the "first society to conduct organised scholarly research into human experiences that challenge contemporary scientific models." It does not however, since its inception in 1882, hold any corporate opinions: SPR members assert a variety of beliefs with regard to the nature of the phenomena studied. - A Crookes tube is an early experimental electrical discharge tube, with vacuum, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. - Florence Cook ( ca 1856 -- 22 April 1904 ) was a medium who claimed to materialise a spirit , '' Katie King '' . The question of whether the spirit was real or a fraud was a notable public controversy of the mid- 1870s . Her abilities were endorsed by Sir William Crookes but many observers were sceptical of Crookes 's investigations , both at the time and subsequently . - The Crookes radiometer, also known as a light mill, consists of an airtight glass bulb, containing a partial vacuum. Inside are a set of vanes which are mounted on a spindle. The vanes rotate when exposed to light, with faster rotation for more intense light, providing a quantitative measurement of electromagnetic radiation intensity. The reason for the rotation was a cause of much scientific debate in the ten years following the invention of the device, but in 1879 the currently accepted explanation for the rotation was published. Today the device is mainly used in physics education as a demonstration of a heat engine run by light energy. After reading the paragraphs above, we are interested in knowing the entity with which 'florence cook' exhibits the relationship of 'occupation'. Find the answer from the choices below.
