[EX Q]: Question: How many songs are on the album that "Sometimes" is part of? Passage:Before recording her debut album, Spears had originally envisioned it in the style of "Sheryl Crow music, but younger [and] more adult contemporary". However, the singer agreed with her label's appointment of producers, who had the objective to reach a teen public at the time. She flew to Cheiron Studios in Stockholm, Sweden, where half of the album was recorded the spring of 1998, with producers Max Martin, Denniz Pop and Rami Yacoub, among others. "Sometimes" was written by Jörgen Elofsson, and produced by Per Magnusson and David Kreuger. Spears recorded the vocals for the song in May 1998, at Cheiron Studios in Stockholm, Sweden. It was also mixed at Cheiron Studios by Martin. Esbjörn Öhrwall played the acoustic guitar, while bass guitar was done by Thomas Lindberg. Keyboards and programming was done by Kreuger, and additional keyboards by Magnusson. Background vocals were provided by Anders von Hoffsten. Spears also co-wrote and recorded a track called "I'm So Curious", produced by Eric Foster White, that was released as a B-side to "Sometimes". The track was recorded in 1997 at 4MW East Studios in New Jersey. "Sometimes" was released as the second single from ...Baby One More Time on April 30, 1999.

[EX Q]: Question: Of the two colonies captured by Philip, which one was established first? Passage:Athens and Macedon had been at war since 356 BC, after Philip's capture of the Athenian colonies of Pydna and Potidea. Shortly afterwards, the Third Sacred War began after the Phocian seizure of the Temple of Apollo in Delphi. Athens allied herself with Phocis, against the other members of the Amphictyonic League. In 354 or 353 BCE, the Thessalians, having been defeated by the Phocians, requested that Philip become archon of Thessaly, to which Philip assented, drawing Macedon into the Sacred War. In 352 BC, Philip's erstwhile ally, the Chalkidian League (led by Olynthos), alarmed by Philip's growing power, sought to ally themselves with Athens, in clear breach of their alliance with Philip. In response, Philip attacked Chalkidiki in 349 BC, and by 348 BC, had completely destroyed the Chalkidian League, razing Olynthos in the process.

[EX Q]: Question: When was the author of JFK and the Unspeakable born? Passage:Jim Garrison said anti-Communist and anti-Castro extremists in the CIA plotted the assassination of Kennedy to maintain tension with the Soviet Union and Cuba, and to prevent a United States withdrawal from Vietnam. James Douglass wrote in JFK and the Unspeakable that the CIA, acting upon the orders of conspirators with the "military industrial complex", killed Kennedy and in the process set up Lee Harvey Oswald as a patsy. Like Garrison, Douglass stated that Kennedy was killed because he was turning away from the Cold War and pursuing paths of nuclear disarmament, rapprochement with Fidel Castro, and withdrawal from the war in Vietnam. Mark Lane — author of Rush to Judgment and Plausible Denial and the attorney who defended Liberty Lobby against a defamation suit brought by former CIA agent E. Howard Hunt — has been described as a leading proponent of the theory that the CIA was responsible for the assassination of Kennedy. Others who believe the CIA was involved include authors Anthony Summers and John M. Newman.
