Input: Transistor
Because the electron mobility is higher than the hole mobility for all semiconductor materials, a given bipolar npn transistor tends to be swifter than an equivalent pnp transistor. GaAs has the highest electron mobility of the three semiconductors. It is for this reason that GaAs is used in high-frequency applications. A relatively recent FET development, the high-electron-mobility transistor (HEMT), has a heterostructure (junction between different semiconductor materials) of aluminium gallium arsenide (AlGaAs)-gallium arsenide (GaAs) which has twice the electron mobility of a GaAs-metal barrier junction. Because of their high speed and low noise, HEMTs are used in satellite receivers working at frequencies around 12 GHz. HEMTs based on gallium nitride and aluminium gallium nitride (AlGaN/GaN HEMTs) provide a still higher electron mobility and are being developed for various applications.

What are common applications of HEMT?
Output: satellite receivers

Input: A cappella
Instruments have divided Christendom since their introduction into worship. They were considered a Catholic innovation, not widely practiced until the 18th century, and were opposed vigorously in worship by a number of Protestant Reformers, including Martin Luther (14831546), Ulrich Zwingli, John Calvin (15091564) and John Wesley (17031791). Alexander Campbell referred to the use of an instrument in worship as "a cow bell in a concert". In Sir Walter Scott's The Heart of Midlothian, the heroine, Jeanie Deans, a Scottish Presbyterian, writes to her father about the church situation she has found in England (bold added):

What was the name of the book in which Jeanie Deans is the protagonist?
Output: The Heart of Midlothian

Input: Somalis
A number of writing systems have been used over the years for transcribing the language. Of these, the Somali alphabet is the most widely used, and has been the official writing script in Somalia since the government of former President of Somalia Mohamed Siad Barre formally introduced it in October 1972. The script was developed by the Somali linguist Shire Jama Ahmed specifically for the Somali language, and uses all letters of the English Latin alphabet except p, v and z. Besides Ahmed's Latin script, other orthographies that have been used for centuries for writing Somali include the long-established Arabic script and Wadaad's writing. Indigenous writing systems developed in the twentieth century include the Osmanya, Borama and Kaddare scripts, which were invented by Osman Yusuf Kenadid, Abdurahman Sheikh Nuur and Hussein Sheikh Ahmed Kaddare, respectively.

Who created the Somali alphabet?
Output: Shire Jama Ahmed

Input: Classical music
Typical stringed instruments of the early period include the harp, lute, vielle, and psaltery, while wind instruments included the flute family (including recorder), shawm (an early member of the oboe family), trumpet, and the bagpipes. Simple pipe organs existed, but were largely confined to churches, although there were portable varieties. Later in the period, early versions of keyboard instruments like the clavichord and harpsichord began to appear. Stringed instruments such as the viol had emerged by the 16th century, as had a wider variety of brass and reed instruments. Printing enabled the standardization of descriptions and specifications of instruments, as well as instruction in their use.

What enabled descriptions and specification of instruments?
Output:
Printing
