Passage: Minogue has been inspired by and compared to Madonna throughout her career. Her producer, Pete Waterman, recalled Minogue during the early years of her success with the observation: "She was setting her sights on becoming the new Prince or Madonna ... What I found amazing was that she was outselling Madonna four to one, but still wanted to be her." Minogue received negative comments that her Rhythm of Love tour in 1991 was too similar visually to Madonna's Blond Ambition World Tour, for which critics labelled her a Madonna wannabe. Rufus Wainwright wrote for the Observer Music Monthly, "Madonna subverts everything for her own gain. I went to see her London show and it was all so dour and humourless. She surpasses even Joan Crawford in terms of megalomania. Which in itself makes her a kind of dark, gay icon ... I love Kylie, she's the anti-Madonna. Self-knowledge is a truly beautiful thing and Kylie knows herself inside out. She is what she is and there is no attempt to make quasi-intellectual statements to substantiate it. She is the gay shorthand for joy." Kathy McCabe for The Telegraph noted that Minogue and Madonna follow similar styles in music and fashion, but concluded, "Where they truly diverge on the pop-culture scale is in shock value. Minogue's clips might draw a gasp from some but Madonna's ignite religious and political debate unlike any other artist on the planet ... Simply, Madonna is the dark force; Kylie is the light force." Rolling Stone commented that, with the exception of the US, Minogue is regarded throughout the world as "an icon to rival Madonna", saying, "Like Madonna, Minogue was not a virtuosic singer but a canny trend spotter." Minogue has said of Madonna, "Her huge influence on the world, in pop and fashion, meant that I wasn't immune to the trends she created. I admire Madonna greatly but in the beginning she made it difficult for artists like me, she had done everything there was to be done", and "Madonna's the Queen of Pop, I'm the princess. I'm quite happy with that."In January 2007, Madame Tussauds in London unveiled its fourth waxwork of Minogue; only Queen Elizabeth II has had more models created. During the same week a bronze cast of her hands was added to Wembley Arena's "Square of Fame". On 23 November 2007, a bronze statue of Minogue was unveiled at Melbourne Docklands for permanent display. 
Question: What is the last name of the singer that had their London concert described as dour and humourless?
Minogue.

Passage: A NASA spacecraft lands on an unknown planet and begins to take rock and soil samples. Four aliens discover it and are sucked into the craft through its vacuum tube, after which it makes its way back to Earth. The aliens are able to escape from a government base by using their powers (with which they can destroy or heal anything they touch). During the escape, the youngest one hides in a passing van, occupied by a boy named Eric Cruise who uses a wheelchair, his older brother, Michael, and their single mother, Janet, who are moving to California from Illinois.
Shortly after the Cruise family arrives at their new home, Eric becomes suspicious of the alien's presence. The next morning, he finds that the creature has trashed most of the house and learns its identity, but is blamed alongside his brother by their mother for what has happened. After seeing the creature again, Eric tries to catch up to him, but ends up sliding down a hill and falls into a lake, where he nearly drowns, but is rescued by the alien. Eric is not believed at all when he tries to tell his family about the creature's actions.
Later that night, he sets a trap with the help of his new friend, Debbie, who had also seen the alien. The two trap him inside a vacuum cleaner, which malfunctions and causes the entire neighborhood to suffer a power surge. After the alien is released, Michael now believes Eric, but it leaves before Janet can be convinced. Eric's behavior towards the alien changes after he fixes all of the damage he caused to the house, and leaves behind several newspaper clippings which Eric believes are an attempt to communicate. 
Question: Who is attempting to communicate with Eric?
the alien.

Passage: Peter Hall directed the Bayreuth Ring after Chéreau. His version, staged 1983–86, portrayed the natural innocence of the Rhinemaidens in the simplest of ways; they were naked. Keith Warner adapted this feature in his Ring production for the Royal Opera House Covent Garden, first staged 2004–06. A Covent Garden spokesman explained "The maidens are children of innocence, a vision of nature – and as soon as someone appears they hastily throw on some clothes to protect their modesty." While Warner relies on lighting to achieve an underwater effect, Hall used a Pepper's ghost illusion: mirrors at a 45° angle made the Rhinemaidens appear to swim vertically when the performers were in fact swimming horizontally in a shallow basin.Although the roles of the Rhinemaidens are relatively small, they have been sung by notable singers better known for performing major roles in Wagnerian and other repertoire. The first person to sing the part of Woglinde in full was Lilli Lehmann at Bayreuth in 1876. In 1951, when the Bayreuth Festival re-opened after the Second World War, the same part was taken by Elisabeth Schwarzkopf. Other Bayreuth Rhinemaidens include  Helga Dernesch who sang Wellgunde there between 1965 and 1967. Lotte Lehmann  played Wellgunde at the Hamburg State Opera between 1912 and 1914 and the Vienna State Opera in 1916.   Recorded Rhinemaidens have included Sena Jurinac for Furtwängler and RAI, Lucia Popp and Gwyneth Jones for Georg Solti, and Helen Donath and Edda Moser for Karajan. 
Question: What is the first name of the person who relies on lighting to achieve an underwater effect?

Keith.
