The problem: Answer a question about this article:
As advances and specialization have made new scientific research inaccessible to most audiences, the "literary" nature of science writing has become less pronounced over the last two centuries. Now, science appears mostly in journals. Scientific works of Aristotle, Copernicus, and Newton still exhibit great value, but since the science in them has largely become outdated, they no longer serve for scientific instruction. Yet, they remain too technical to sit well in most programmes of literary study. Outside of "history of science" programmes, students rarely read such works.
The segregation of science writing means that articles in those subjects primarily appear where?
****
The answer: journals

The problem: Answer a question about this article:
The early currency of the United States did not exhibit faces of presidents, as is the custom now; although today, by law, only the portrait of a deceased individual may appear on United States currency. In fact, the newly formed government was against having portraits of leaders on the currency, a practice compared to the policies of European monarchs. The currency as we know it today did not get the faces they currently have until after the early 20th century; before that "heads" side of coinage used profile faces and striding, seated, and standing figures from Greek and Roman mythology and composite Native Americans. The last coins to be converted to profiles of historic Americans were the dime (1946) and the Dollar (1971).
Other than Greek and Roman mythology, who else was featured on the "heads" side of past coins?
****
The answer: composite Native Americans

The problem: Answer a question about this article:
Because of the vastness and diversity of the territory occupied by Slavic people, there were several centers of Slavic consolidation. In the 19th century, Pan-Slavism developed as a movement among intellectuals, scholars, and poets, but it rarely influenced practical politics and did not find support in some nations that had Slavic origins. Pan-Slavism became compromised when the Russian Empire started to use it as an ideology justifying its territorial conquests in Central Europe as well as subjugation of other ethnic groups of Slavic origins such as Poles and Ukrainians, and the ideology became associated with Russian imperialism. The common Slavic experience of communism combined with the repeated usage of the ideology by Soviet propaganda after World War II within the Eastern bloc (Warsaw Pact) was a forced high-level political and economic hegemony of the USSR dominated by Russians. A notable political union of the 20th century that covered most South Slavs was Yugoslavia, but it ultimately broke apart in the 1990s along with the Soviet Union.
When did Yugoslavia break apart?
****
The answer: 1990s
