instruction:
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
question:
What event caused a potential change in presidental leadership, Context: The House of Representatives currently has 59 members elected for a five-year term, 56 members by proportional representation and 3 observer members representing the Armenian, Latin and Maronite minorities. 24 seats are allocated to the Turkish community but remain vacant since 1964. The political environment is dominated by the communist AKEL, the liberal conservative Democratic Rally, the centrist Democratic Party, the social-democratic EDEK and the centrist EURO.KO. In 2008, Dimitris Christofias became the country's first Communist head of state. Due to his involvement in the 2012–13 Cypriot financial crisis, Christofias did not run for re-election in 2013. The Presidential election in 2013 resulted in Democratic Rally candidate Nicos Anastasiades winning 57.48% of the vote. As a result, Anastasiades was sworn in on and has been President since 28 February 2013.
answer:
the 2012–13 Cypriot financial crisis


question:
What did reading Carl Menger's work do for Hayek?, Context: During Hayek's years at the University of Vienna, Carl Menger's work on the explanatory strategy of social science and Friedrich von Wieser's commanding presence in the classroom left a lasting influence on him. Upon the completion of his examinations, Hayek was hired by Ludwig von Mises on the recommendation of Wieser as a specialist for the Austrian government working on the legal and economic details of the Treaty of Saint Germain. Between 1923 and 1924 Hayek worked as a research assistant to Prof. Jeremiah Jenks of New York University, compiling macroeconomic data on the American economy and the operations of the US Federal Reserve.
answer:
left a lasting influence


question:
How common are carbonates and deposits in North America?, Context: To the north of Africa the Tethys Sea continued to narrow. Broad shallow seas advanced across central North America (the Western Interior Seaway) and Europe, then receded late in the period, leaving thick marine deposits sandwiched between coal beds. At the peak of the Cretaceous transgression, one-third of Earth's present land area was submerged. The Cretaceous is justly famous for its chalk; indeed, more chalk formed in the Cretaceous than in any other period in the Phanerozoic. Mid-ocean ridge activity—or rather, the circulation of seawater through the enlarged ridges—enriched the oceans in calcium; this made the oceans more saturated, as well as increased the bioavailability of the element for calcareous nanoplankton. These widespread carbonates and other sedimentary deposits make the Cretaceous rock record especially fine. Famous formations from North America include the rich marine fossils of Kansas's Smoky Hill Chalk Member and the terrestrial fauna of the late Cretaceous Hell Creek Formation. Other important Cretaceous exposures occur in Europe and China. In the area that is now India, massive lava beds called the Deccan Traps were laid down in the very late Cretaceous and early Paleocene.
answer:

widespread
