Problem: Rajasthan:

Rajasthan is known for its traditional, colorful art. The block prints, tie and dye prints, Bagaru prints, Sanganer prints, and Zari embroidery are major export products from Rajasthan. Handicraft items like wooden furniture and crafts, carpets, and blue pottery are commonly found here. Shopping reflects the colorful culture, Rajasthani clothes have a lot of mirror work and embroidery. A Rajasthani traditional dress for females comprises an ankle-length skirt and a short top, also known as a lehenga or a chaniya choli. A piece of cloth is used to cover the head, both for protection from heat and maintenance of modesty. Rajasthani dresses are usually designed in bright colors like blue, yellow and orange.

Bagaru and Sanganer represent what type of art?

A: prints


Problem: Pharmaceutical industry:

Ehrlich’s approach of systematically varying the chemical structure of synthetic compounds and measuring the effects of these changes on biological activity was pursued broadly by industrial scientists, including Bayer scientists Josef Klarer, Fritz Mietzsch, and Gerhard Domagk. This work, also based in the testing of compounds available from the German dye industry, led to the development of Prontosil, the first representative of the sulfonamide class of antibiotics. Compared to arsphenamine, the sulfonamides had a broader spectrum of activity and were far less toxic, rendering them useful for infections caused by pathogens such as streptococci. In 1939, Domagk received the Nobel Prize in Medicine for this discovery. Nonetheless, the dramatic decrease in deaths from infectious diseases that occurred prior to World War II was primarily the result of improved public health measures such as clean water and less crowded housing, and the impact of anti-infective drugs and vaccines was significant mainly after World War II.

What causes Streptococci?

A: pathogens


Problem: Mandolin:

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.

 Who contributed to the idea that the mandolin was not just a fad?
---
A: unanswerable


Problem: Neptune:

Some of the earliest recorded observations ever made through a telescope, Galileo's drawings on 28 December 1612 and 27 January 1613, contain plotted points that match up with what is now known to be the position of Neptune. On both occasions, Galileo seems to have mistaken Neptune for a fixed star when it appeared close—in conjunction—to Jupiter in the night sky; hence, he is not credited with Neptune's discovery. At his first observation in December 1612, Neptune was almost stationary in the sky because it had just turned retrograde that day. This apparent backward motion is created when Earth's orbit takes it past an outer planet. Because Neptune was only beginning its yearly retrograde cycle, the motion of the planet was far too slight to be detected with Galileo's small telescope. In July 2009, University of Melbourne physicist David Jamieson announced new evidence suggesting that Galileo was at least aware that the 'star' he had observed had moved relative to the fixed stars.

Who drew Neptune after observing it with a telescope?

A:
Galileo
