In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Let me give you an example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

OK. solve this:
Passage: "Ooh La La", Supernature's opening track, inspired by T. Rex, was chosen as its lead single "because it was up and in your face and it carried on the theme of the glammy, discoey beat from the last album". It was the duo's first song to feature the electric guitar, and received positive reviews, often being noted as a highlight of the album. "Ooh La La" became Goldfrapp's most successful single on the UK Singles Chart to date when it peaked at number four, while topping the Billboard Hot Dance Club Play chart in the United States. The second track, "Lovely 2 C U", received mixed reviews from critics, with one reviewer stating that it was the "worst offender of sounding by-numbers, its lazy glam affectations sounding all the worse amid a chorus striking only in its complete dullness"."Ride a White Horse", the third single, was inspired by the disco era. Like previous singles from the album, the song was another top-20 single in the UK, where it peaked at number 15. The ballads "You Never Know" and "Let It Take You" have minimal background electronics, and were generally well received by critics, who drew comparisons to Goldfrapp's debut album Felt Mountain. Goldfrapp's performance on "You Never Know" was described as "chameleonic" with odes to Debbie Harry and Siouxsie Sioux. "Fly Me Away", another synth ballad, had an associated music video which featured Goldfrapp as an animated doll; the video, however, was never released. Serving as the fourth and final single from Supernature, the song was not heavily promoted and was less commercially successful than the other singles, peaking at number 26 on the UK chart. "Slide In", an electroclash song about sex, and "Koko" were compared to Gary Numan's early compositions."Satin Chic" is a disco song with glam rock and cabaret influences, similar to early Elton John. Cited by Goldfrapp and Gregory as their favourite song on Supernature, it was remixed by The Flaming Lips, and issued as a limited-edition single on 4 September 2006. The 10th track, "Time Out from the World", features an orchestra and whispered vocals by Goldfrapp. Critics liked the song, writing that it was an "exception to the prevailing style of Supernature" due to its "haunting, yet glamorous, atmospherics". The album's closing track and second single "Number 1" is about the importance and meanings of relationships. The song, which is based around a synth and bass arrangement, reached number nine on the UK Singles Chart and number one on the US Hot Dance Club Play chart.
Answer:
What are the last names of the people in the duo whose first song to feature electric guitar was "Ooh La La?"?
