Passage: Diana Scott is a beautiful, bored young model married to Tony Bridges. One day, Diana meets Robert Gold, a literary interviewer/director for television arts programmes, by chance when she is spotted on the street by his roving film crew and interviewed by him about young people's views on convention. Diana is invited to watch the final edit in the TV studio and there their relationship starts. After liaisons in bleak hotel rooms they leave their spouses (and, in Robert's case, children) and move into an apartment.
As a couple, they become part of the fashionable London media/arts set. Initially, Diana is jealous when Robert sees his wife while visiting his children, but she quickly loses this attachment when she mixes with the predatory males of the media, arts and advertising scene, particularly Miles Brand, a powerful advertising executive for the "Glass Corporation" who gets her a part in a trashy thriller after she has sex with him. The bookish Robert prefers the quiet life; it is he who now becomes jealous, but increasingly detached, depressed and lonely.
Diana attends a high-class charity draw for world hunger for which she is the face. The event, adorned by giant images of African famine victims, is at the height of cynical hypocrisy and bad taste, showing Diana's rich white set, which now includes the establishment, playing at concern, gorging themselves, gambling and generally behaving decadently.
Already showing signs of stress from constantly maintaining the carefree look demanded by the false, empty lifestyle to which she has become a prisoner, Diana becomes pregnant, and has an abortion. 
Question: What is the last name of the person who got a part in a trashy thriller?
Scott.

Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai.  The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janáček operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North. 
Question: What is the first name of the person who unwell and unhappy during his brief tenure?
Charles.

Passage: In his 1924 publication dealing with Kent, the archaeologist O. G. S. Crawford, then working as the archaeological officer for the Ordnance Survey, listed the Coldrum Stones alongside the other Medway Megaliths. In 1926, the Coldrum Stones were given to The National Trust, which dedicated it as a memorial to the Kentish prehistorian Benjamin Harrison. A plaque was erected to mark this, which erroneously termed the monument a stone circle; in 1953, the archaeologist Leslie Grinsell expressed the view that "it is hoped that this error may be rectified in the near future". Still owned by the Trust, the site is open to visitors all year round, free of charge. On their website, the Trust advises visitors to look for "stunning views from the top of the barrow". John H. Evans characterised the site as "the most impressive" of the Medway Megaliths, while Grinsell described it as "the finest and most complete" of the group.Among the Pagans who use the Coldrum Stones for their ritual activities, there is general satisfaction with the Trust's management of the site, although some frustration at the poor access for disabled visitors. A patch of scorched earth exists on the grass in the centre of the monument, perhaps used by Pagans as well as non-Pagans, and the Trust warden responsible for the site has decided to leave it there rather than seeding it over, in order to encourage any who do light fires to do so in the same spot rather than nearer to the stones themselves. The site also faces a problem from litter left by visitors, although Pagans who regularly visit the site clean this up. 
Question: What is the name of the site for which the responsible Trust warden has chosen to leave the patch of scorched earth rather than seeding it over?

Coldrum Stones.
