Passage: Robert and Cathy Wilson (Robert Donat and Deborah Kerr) are a timid married couple in 1940 London. He is a bookkeeper, she a bored housewife. However, their tedium-filled lives are drastically changed by the war. He enlists in the Royal Navy, while she (against his wishes) joins the Wrens. During the three years the couple are apart, they are transformed, each becoming much more self-confident.
Cathy's assertive new friend, Dizzy Clayton, helps her break out of her shell. She begins going out with Dizzy's cousin, naval architect Richard, who falls in love with her. However, she remains faithful (if unenthusiastically) to her husband.
Meanwhile, Robert toughens up on sea duty and in time becomes a petty officer. His hands are badly burned when his ship is sunk, but he stoically rows in the lifeboat for five days without complaint. He recuperates in a hospital, tended by Elena, a beautiful nurse. On the last night of his stay, he asks her out to dinner. He is attracted to her, but she informs him that she lost her beloved husband only six months earlier, kisses him, and leaves.
Robert and Cathy both receive ten-day leaves, but each dreads being reunited with the dowdy spouse each remembers and being forced back into the dreary life they shared. 
Question: What is the first name of the cousin of the person who falls in love with the bored housewife?
Dizzy.

Passage: By the late 1950s, Covent Garden was gradually abandoning its policy of productions in the vernacular; such singers as Maria Callas would not relearn their roles in English. This made it easier for Tucker to point up the difference between the two London opera companies. While Covent Garden engaged international stars, Sadler's Wells focused on young British and Commonwealth performers. Colin Davis was appointed musical director in succession to Gibson in 1961. The repertoire continued to mix familiar and unfamiliar operas. Novelties in Davis's time included Pizzetti's Murder in the Cathedral, Stravinsky's Oedipus rex, Richard Rodney Bennett's The Mines of Sulphur and more Janáček. Sadler's Wells's traditional policy of giving all operas in English continued, with only two exceptions: Oedipus rex, which was sung in Latin, and Monteverdi's L'Orfeo, sung in Italian, for reasons not clear to the press. In January 1962, the company gave its first Gilbert and Sullivan opera, Iolanthe, on the day on which the Savoy operas came out of copyright and the D'Oyly Carte monopoly ended.  The production was well received (it was successfully revived for many seasons until 1978) and was followed by a production of The Mikado in May of the same year.The Islington theatre was by now clearly too small to allow the company to achieve any further growth. A study conducted for the Arts Council reported that in the late 1960s the two Sadler's Wells companies comprised 278 salaried performers and 62 guest singers. The company had experience of playing in a large West End theatre, such as its 1958 sell-out production of The Merry Widow that had transferred to the 2,351-seat London Coliseum for a summer season. Ten years later, the lease of the Coliseum became available.  Stephen Arlen, who had succeeded Tucker as managing director, was the primary advocate for moving the company. After intense negotiations and fund-raising, a ten-year lease was signed in 1968.  One of the company's last productions at the Islington theatre was Wagner's The Mastersingers, conducted by Goodall in 1968, which 40 years later was described by Gramophone magazine as "legendary". The company left Sadler's Wells with a revival of the work with which it had re-opened the theatre in 1945, Peter Grimes. Its last performance at the Rosebery Avenue theatre was on 15 June 1968. 
Question: What theatre did the Sadler's Wells company perform prior to 1968?
Islington theatre.

Passage: While flying a routine mission for the U.S. Navy from his aircraft carrier, an emergency causes Lieutenant Robin "Rob" Crusoe to eject from his F-8 Crusader into the ocean. Crusoe drifts on the ocean in an emergency life raft for several days and nights until landing on an uninhabited island. Crusoe builds a shelter for himself, fashions new clothing out of available materials, and begins to scout the island, discovering an abandoned Japanese submarine from World War II. Scouring the submarine, Crusoe also discovers a NASA astrochimp named Floyd, played by Dinky.Using tools and blueprints found in the submarine, Crusoe and Floyd construct a Japanese pavilion, a golf course, and a mail delivery system for sending bottles containing missives to his fiancee out to sea.
Soon after, Crusoe finds that the island is not entirely uninhabited when he encounters a beautiful island girl, whom he names Wednesday. Wednesday recounts that due to her unwillingness to marry, her chieftain father, Tanamashuhi, plans to sacrifice her and her sisters to Kaboona, an immense effigy on the island with whom he pretends to communicate.
The day Tanamashu arrives on the island, Crusoe uses paraphernalia from the submarine to combat him, culminating in the destruction of the Kaboona statue.
After the battle, Crusoe and Tanamashu make peace. But when Crusoe makes it known that he does not wish to marry Wednesday, he is forced to flee to avoid her wrath. Pursued by a mob of irate island women, Crusoe is spotted by a U.S. Navy helicopter and he and Floyd narrowly escape with their lives. Large crowds turn out for their arrival on an aircraft carrier deck, but Floyd steals all the limelight. 
Question: What did Robin and the astrochimp build that makes it possible for Robin to communicate with his fiancee?

a mail delivery system.
