Input: Read this: Service trials demonstrated another problem however: that ranging and tracking the new high-speed targets was almost impossible. At short range, the apparent target area is relatively large, the trajectory is flat and the time of flight is short, allowing to correct lead by watching the tracers. At long range, the aircraft remains in firing range for a long time, so the necessary calculations can in theory be done by slide rules - though, because small errors in distance cause large errors in shell fall height and detonation time, exact ranging is crucial. For the ranges and speeds that the Bofors worked at, neither answer was good enough.
Question: At long range what, in theory, could be used to set ranging calculations?

Output: slide rules

Input: Read this: At launch, the Xbox 360 was available in two configurations: the "Xbox 360" package (unofficially known as the 20 GB Pro or Premium), priced at US$399 or GB279.99, and the "Xbox 360 Core", priced at US$299 and GB209.99. The original shipment of the Xbox 360 version included a cut-down version of the Media Remote as a promotion. The Elite package was launched later at US$479. The "Xbox 360 Core" was replaced by the "Xbox 360 Arcade" in October 2007 and a 60 GB version of the Xbox 360 Pro was released on August 1, 2008. The Pro package was discontinued and marked down to US$249 on August 28, 2009 to be sold until stock ran out, while the Elite was also marked down in price to US$299.
Question: When was the Core package launched?

Output: unanswerable

Input: Read this: Bateman was responsible for the building of 36 new buildings for the university both on and off campus, including the expansion of the Harold B. Lee Library. He was also one of several key college leaders who brought about the creation of the Mountain West Conference, which BYU's athletics program joined BYU previously participated in the Western Athletic Conference. A BYU satellite TV network also opened in 2000 under his leadership. Bateman was also president during the September 11th attacks in 2001. The planes crashed on a Tuesday, hours before the weekly devotional normally held at BYU. Previous plans for the devotional were altered, as Bateman led the student body in a prayer for peace. Bateman was followed by Cecil O. Samuelson in 2003. Samuelson was succeeded by Kevin J Worthen in 2014.
Question: What infamous event occurred during Bateman's term as president?

Output: the September 11th attacks

Input: Read this: So-called voiced aspirated consonants are nearly always pronounced instead with breathy voice, a type of phonation or vibration of the vocal folds. The modifier letter after a voiced consonant actually represents a breathy-voiced or murmured dental stop, as with the "voiced aspirated" bilabial stop b in the Indo-Aryan languages. This consonant is therefore more accurately transcribed as b, with the diacritic for breathy voice, or with the modifier letter b, a superscript form of the symbol for the voiced glottal fricative .
Question: What represents the "voice aspirated" bilabial stop in the English language?

Output:
unanswerable
