QUES: The international repertoire of music for mandolin is almost unlimited, and musicians use it to play various types of music. This is especially true of violin music, since the mandolin has the same tuning of the violin. Following its invention and early development in Italy the mandolin spread throughout the European continent. The instrument was primarily used in a classical tradition with Mandolin orchestras, so called Estudiantinas or in Germany Zupforchestern appearing in many cities. Following this continental popularity of the mandolin family local traditions appeared outside of Europe in the Americas and in Japan. Travelling mandolin virtuosi like Giuseppe Pettine, Raffaele Calace and Silvio Ranieri contributed to the mandolin becoming a "fad" instrument in the early 20th century. This "mandolin craze" was fading by the 1930s, but just as this practice was falling into disuse, the mandolin found a new niche in American country, old-time music, bluegrass and folk music. More recently, the Baroque and Classical mandolin repertory and styles have benefited from the raised awareness of and interest in Early music, with media attention to classical players such as Israeli Avi Avital, Italian Carlo Aonzo and American Joseph Brent.

QUES: Although the Estonian and Germanic languages are of very different origins, one can identify many similar words in Estonian and English, for example. This is primarily because the Estonian language has borrowed nearly one third of its vocabulary from Germanic languages, mainly from Low Saxon (Middle Low German) during the period of German rule, and High German (including standard German). The percentage of Low Saxon and High German loanwords can be estimated at 22–25 percent, with Low Saxon making up about 15 percent.[citation needed]

When did Low Saxon stop being part of the Estonian language?

QUES: The United States launched three more Mercury flights after Glenn's: Aurora 7 on May 24, 1962 duplicated Glenn's three orbits; Sigma 7 on October 3, 1962, six orbits; and Faith 7 on May 15, 1963, 22 orbits (32.4 hours), the maximum capability of the spacecraft. NASA at first intended to launch one more mission, extending the spacecraft's endurance to three days, but since this would not beat the Soviet record, it was decided instead to concentrate on developing Project Gemini.

How many more Mercury missions were there after John Glenn's?
