Problem: Mandolin:

A mandolin (Italian: mandolino pronounced [mandoˈliːno]; literally "small mandola") is a musical instrument in the lute family and is usually plucked with a plectrum or "pick". It commonly has four courses of doubled metal strings tuned in unison (8 strings), although five (10 strings) and six (12 strings) course versions also exist. The courses are normally tuned in a succession of perfect fifths. It is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass.

Problem: Comics:

Similar to the problems of defining literature and film, no consensus has been reached on a definition of the comics medium, and attempted definitions and descriptions have fallen prey to numerous exceptions. Theorists such as Töpffer, R. C. Harvey, Will Eisner, David Carrier, Alain Rey, and Lawrence Grove emphasize the combination of text and images, though there are prominent examples of pantomime comics throughout its history. Other critics, such as Thierry Groensteen and Scott McCloud, have emphasized the primacy of sequences of images. Towards the close of the 20th century, different cultures' discoveries of each other's comics traditions, the rediscovery of forgotten early comics forms, and the rise of new forms made defining comics a more complicated task.

Comic critics, such as McCloud, stressed that sequences of what should be primary?
---
A: images


Problem: Josip Broz Tito:

Tito was interred in a mausoleum in Belgrade, which forms part of a memorial complex in the grounds of the Museum of Yugoslav History (formerly called "Museum 25 May" and "Museum of the Revolution"). The actual mausoleum is called House of Flowers (Kuća Cveća) and numerous people visit the place as a shrine to "better times". The museum keeps the gifts Tito received during his presidency. The collection also includes original prints of Los Caprichos by Francisco Goya, and many others. The Government of Serbia has planned to merge it into the Museum of the History of Serbia. At the time of his death, speculation began about whether his successors could continue to hold Yugoslavia together. Ethnic divisions and conflict grew and eventually erupted in a series of Yugoslav wars a decade after his death.

What name was given to Tito's mausoleum?
---
A: House of Flowers


Problem: Han dynasty:

From roughly 115 to 60 BC, Han forces fought the Xiongnu over control of the oasis city-states in the Tarim Basin. Han was eventually victorious and established the Protectorate of the Western Regions in 60 BC, which dealt with the region's defense and foreign affairs. The Han also expanded southward. The naval conquest of Nanyue in 111 BC expanded the Han realm into what are now modern Guangdong, Guangxi, and northern Vietnam. Yunnan was brought into the Han realm with the conquest of the Dian Kingdom in 109 BC, followed by parts of the Korean Peninsula with the colonial establishments of Xuantu Commandery and Lelang Commandery in 108 BC. In China's first known nationwide census taken in 2 AD, the population was registered as having 57,671,400 individuals in 12,366,470 households.
