Problem: Please answer a question about the following article about Aircraft carrier:
If the aircraft are VTOL-capable or helicopters, they do not need to decelerate and hence there is no such need. The arrested-recovery system has used an angled deck since the 1950s because, in case the aircraft does not catch the arresting wire, the short deck allows easier take off by reducing the number of objects between the aircraft and the end of the runway. It also has the advantage of separating the recovery operation area from the launch area. Helicopters and aircraft capable of vertical or short take-off and landing (V/STOL) usually recover by coming abreast the carrier on the port side and then using their hover capability to move over the flight deck and land vertically without the need for arresting gear.
What type of aircraft have no need to decelerate?
A: VTOL-capable or helicopters
Problem: Please answer a question about the following article about Capacitor:
Charles Pollak (born Karol Pollak), the inventor of the first electrolytic capacitors, found out that the oxide layer on an aluminum anode remained stable in a neutral or alkaline electrolyte, even when the power was switched off. In 1896 he filed a patent for an "Electric liquid capacitor with aluminum electrodes." Solid electrolyte tantalum capacitors were invented by Bell Laboratories in the early 1950s as a miniaturized and more reliable low-voltage support capacitor to complement their newly invented transistor.
Who invented the first electrolytic capacitor?
A: Charles Pollak
Problem: Please answer a question about the following article about Kanye West:
Beginning his second effort that fall, West would invest two million dollars and take over a year to craft his second album. West was significantly inspired by Roseland NYC Live, a 1998 live album by English trip hop group Portishead, produced with the New York Philharmonic Orchestra. Early in his career, the live album had inspired him to incorporate string arrangements into his hip-hop production. Though West had not been able to afford many live instruments around the time of his debut album, the money from his commercial success enabled him to hire a string orchestra for his second album Late Registration. West collaborated with American film score composer Jon Brion, who served as the album's co-executive producer for several tracks. Although Brion had no prior experience in creating hip-hop records, he and West found that they could productively work together after their first afternoon in the studio where they discovered that neither confined his musical knowledge and vision to one specific genre. Late Registration sold over 2.3 million units in the United States alone by the end of 2005 and was considered by industry observers as the only successful major album release of the fall season, which had been plagued by steadily declining CD sales.
What composer worked alongside Kanye on the album's production?
A: Jon Brion
