Passage: The Slaters of Wolverhampton are plagued with Mrs. Slater's chronic debilitating asthma and her cooking limited to what comes in canned goods that she can heat in boiling water. Mr. Alan Slater is sick with worry and has a cantankerous personality. Nigel longs for a life that is more than a succession of canned-food dinners made from what can be heated in boiling water. When dinner is burnt, the standard substitute of toast is always served. He loves toast, with the crunchy outside giving way to buttery softness inside. Despite her infrequent forays into cooking meals from scratch, his mother's attempts to improve her cooking change nothing before or after her death. His father continues in widowhood with the same cooking style and frequent dinners of toast. The experience brings Nigel to conclude that he is not liked. Nigel learns from a friend that the way in which he could attempt a better relationship with his father is to cook a meal for him.
His cooking efforts are thwarted by the new housekeeper, the married and "common" Mrs. Joan Potter, who seduces Alan with her apple pie and array of gourmet meals. The two start to spend time together: at one point, she exiting her council house through an upstairs window so as not to be found out by her husband. Without announcement, the Slaters move to the Herefordshire countryside along with Mrs. Potter. Nigel co-exists with her but never accepts her. She makes a competition of cooking when the teenaged Nigel's shows an emerging interest in developing his skills at school home economics class cookery lessons. Mrs. Potter's lemon meringue pie becomes Nigel's quest to learn the secret recipe. 
Question: While Nigel's mom has asthma, what makes his dad ill?

Ex Output:
worry.

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?

Ex Output:
Scott.

Passage: In 1983, theater and opera director Peter Sellars proposed to American composer John Adams that he write an opera about Nixon's 1972 visit to China. Sellars was intrigued by Nixon's decision to make the visit, seeing it as both "a ridiculously cynical election ploy ... and a historical breakthrough". Adams, who had not previously attempted an opera, was initially skeptical, assuming that Sellars was proposing a satire. Sellars persisted, however, and Adams, who had interested himself in the origin of myths, came to believe the opera could show how mythic origins may be found in contemporary history.  Both men agreed that the opera would be heroic in nature, rather than poking fun at Nixon or Mao.  Sellars invited Alice Goodman to join the project as librettist,  and the three met at the Kennedy Center in Washington D.C. in 1985 to begin intensive study of the six characters, three American and three Chinese, upon whom the opera would focus. The trio endeavored to go beyond the stereotypes about figures such as Nixon and Chinese Chairman Mao Tse-tung and to examine their personalities.As Adams worked on the opera, he came to see Nixon, whom he had once intensely disliked, as an "interesting character", a complicated individual who sometimes showed emotion in public.  Adams wanted Mao to be "the Mao of the huge posters and Great Leap Forward; I cast him as a heldentenor".  Mao's wife, on the other hand, was to be "not just a shrieking coloratura, but also someone who in the opera's final act can reveal her private fantasies, her erotic desires, and even a certain tragic awareness.  Nixon himself is a sort of Simon Boccanegra, a self-doubting, lyrical, at times self-pitying melancholy baritone."Goodman explained her characterizations:
A writer tends to find her characters in her self, so I can tell you ... that Nixon, Pat, Mme. Mao, Kissinger and the chorus were all 'me.' And the inner lives of Mao and Chou En-Lai, who I couldn't find in myself at all, were drawn from a couple of close acquaintances. 
Question: What are the full names of the three individuals who met at the Kennedy Center in Washing D.C. in 1985 to begin intensive study of the six characters upon whom the opera would focus?

Ex Output:

Peter Sellars.
