Input: A cappella
The Swingle Singers used nonsense words to sound like instruments, but have been known to produce non-verbal versions of musical instruments. Like the other groups, examples of their music can be found on YouTube. Beatboxing, more accurately known as vocal percussion, is a technique used in a cappella music popularized by the hip-hop community, where rap is often performed a cappella also. The advent of vocal percussion added new dimensions to the a cappella genre and has become very prevalent in modern arrangements. Petra Haden used a four-track recorder to produce an a cappella version of The Who Sell Out including the instruments and fake advertisements on her album Petra Haden Sings: The Who Sell Out in 2005. Haden has also released a cappella versions of Journey's "Don't Stop Believin'", The Beach Boys' "God Only Knows" and Michael Jackson's "Thriller". In 2009, Toyota commissioned Haden to perform three songs for television commercials for the third-generation Toyota Prius, including an a cappella version of The Bellamy Brothers' 1970s song "Let Your Love Flow".[citation needed]

What was used to make an a capella recording of The Who Sell Out?
Output: a four-track recorder

Input: Transistor
In a switching circuit, the idea is to simulate, as near as possible, the ideal switch having the properties of open circuit when off, short circuit when on, and an instantaneous transition between the two states. Parameters are chosen such that the "off" output is limited to leakage currents too small to affect connected circuitry; the resistance of the transistor in the "on" state is too small to affect circuitry; and the transition between the two states is fast enough not to have a detrimental effect.

What is a switching circuit trying to simulate when off?
Output: open circuit

Input: Pacific War
Midway proved to be the last great naval battle for two years. The United States used the ensuing period to turn its vast industrial potential into increased numbers of ships, planes, and trained aircrew. At the same time, Japan, lacking an adequate industrial base or technological strategy, a good aircrew training program, or adequate naval resources and commerce defense, fell further and further behind. In strategic terms the Allies began a long movement across the Pacific, seizing one island base after another. Not every Japanese stronghold had to be captured; some, like Truk, Rabaul, and Formosa, were neutralized by air attack and bypassed. The goal was to get close to Japan itself, then launch massive strategic air attacks, improve the submarine blockade, and finally (only if necessary) execute an invasion.

What blockade against Japan  was to be improved on?
Output: submarine blockade

Input: Thuringia
The first railways in Thuringia had been built in the 1840s and the network of main lines was finished around 1880. By 1920, many branch lines had been built, giving Thuringia one of the densest rail networks in the world before World War II with about 2,500 km of track. Between 1950 and 2000 most of the branch lines were abandoned, reducing Thuringia's network by half compared to 1940. On the other hand, most of the main lines were refurbished after 1990, resulting in improved speed of travel. The most important railway lines at present are the Thuringian Railway, connecting Halle and Leipzig via Weimar, Erfurt, Gotha and Eisenach with Frankfurt and Kassel and the Saal Railway from Halle/Leipzig via Jena and Saalfeld to Nuremberg. The former has an hourly ICE/IC service from Dresden to Frankfurt while the latter is served hourly by ICE trains from Berlin to Munich. In 2017, a new high speed line will be opened, diverting long-distance services from these mid-19th century lines. Both ICE routes will then use the Erfurt–Leipzig/Halle high-speed railway, and the Berlin-Munich route will continue via the Nuremberg–Erfurt high-speed railway. Only the segment west of Erfurt of the Frankfurt-Dresden line will continue to be used by ICE trains after 2017, with an increased line speed of 200 km/h (currently 160 km/h). Erfurt's central station, which was completely rebuilt for this purpose in the 2000s (decade), will be the new connection between both ICE lines. The most important regional railway lines in Thuringia are the Neudietendorf–Ritschenhausen railway from Erfurt to Würzburg and Meiningen, the Weimar–Gera railway from Erfurt to Chemnitz, the Sangerhausen–Erfurt railway from Erfurt to Magdeburg, the Gotha–Leinefelde railway from Erfurt to Göttingen, the Halle–Kassel railway from Halle via Nordhausen to Kassel and the Leipzig–Hof railway from Leipzig via Altenburg to Zwickau and Hof. Most regional and local lines have hourly service, but some run only every other hour.

When will the new high speed train be open? 
Output:
In 2017, a new high speed line will be opened,
