Question: Question: How long before "Promise This" was released was the city it was recorded in established? Passage:"Promise This" is an up-tempo dance-pop song written by American songwriter Priscilla Hamilton, British music producer Wayne Wilkins, who was responsible for Cole's debut single "Fight for This Love", and Christopher Jackson. It is written in the music key of C minor with a time signature in common time and a tempo of 151beats per minute. Cole's vocal range spans from G to E. The basic chord progression of the song is Cm, Cm, Cm, Cm, E, B, F, Cm, E, B and F. The song sees Cole singing some of the lyrics in French, referencing the children's song "Alouette". It was recorded in Santa Monica, California, and "finds her contemplating mortality with a cheerful morbidity, asking for prayers over a brutal march beat." Tabloids suggested that the lyrics were based upon her divorce from footballer Ashley Cole, and how her dancer friend Derek Hough nursed her to health while she was suffering from malaria. The Daily Star had also noted Cole's apparent affection in the song by her use of the French word alouette, meaning "skylark".

Question: Question: Of the grasses that the essex skipper eats, which is the longest? Passage:Eggs are laid in strings on the stems of grasses where they remain over the winter. The Essex skipper's favoured foodplant is cock's-foot (Dactylis glomerata), and it rarely uses the small skipper's favoured foodplant Yorkshire fog. Essex skippers' other foods include creeping soft grass (Holcus mollis), couch grass (Elymus repens), timothy-grass (Phleum pratense), meadow foxtail (Alopecurus pratensis), false brome (Brachypodium sylvaticum) and tor-grass (Brachypodium pinnatum). This skipper's caterpillars emerge in the spring and feed until June before forming shelters from leaves tied with silk at the base of the foodplant to pupate. Adults fly from July through August. Like most skippers, they are fairly strictly diurnal, though individuals are very rarely encountered during the night.

Question: Question: When did the conductor at Midori's concert debut begin conducting the New York Philharmonic? Passage:Midori gave her first public performance at the age of six, playing one of the 24 Caprices of Paganini in her native Osaka. In 1982 she and her mother moved to New York City, where Midori started violin studies with Dorothy DeLay at Pre-College Division of Juilliard School and the Aspen Music Festival and School. As her audition piece, Midori performed Bach's thirteen-minute-long Chaconne, generally considered one of the most difficult solo violin pieces. In the same year, she made her concert debut with the New York Philharmonic under Zubin Mehta, a conductor with whom she would later record on the Sony Classical label. In 1986 came her legendary performance of Leonard Bernstein's Serenade at Tanglewood, conducted by Bernstein. During the performance, she broke the E string on her violin, then again on the concertmaster's Stradivarius after she borrowed it. She finished the performance with the associate concertmaster's Guadagnini and received a standing ovation. The next day The New York Times front page carried the headline, "Girl, 14, Conquers Tanglewood with 3 Violins".
