Fiame Mata'afa Faumuina Mulinu'u II, one of the four highest-ranking paramount chiefs in the country, became Samoa's first Prime Minister. Two other paramount chiefs at the time of independence were appointed joint heads of state for life. Tupua Tamasese Mea'ole died in 1963, leaving Malietoa Tanumafili II sole head of state until his death on 11 May 2007, upon which Samoa changed from a constitutional monarchy to a parliamentary republic de facto. The next Head of State, Tuiatua Tupua Tamasese Efi, was elected by the legislature on 17 June 2007 for a fixed five-year term, and was re-elected unopposed in July 2012.

Context and question: One way of proving that a given disease is "infectious", is to satisfy Koch's postulates (first proposed by Robert Koch), which demands that the infectious agent be identified only in patients and not in healthy controls, and that patients who contract the agent also develop the disease. These postulates were first used in the discovery that Mycobacteria species cause tuberculosis. Koch's postulates can not be applied ethically for many human diseases because they require experimental infection of a healthy individual with a pathogen produced as a pure culture. Often, even clearly infectious diseases do not meet the infectious criteria. For example, Treponema pallidum, the causative spirochete of syphilis, cannot be cultured in vitro - however the organism can be cultured in rabbit testes. It is less clear that a pure culture comes from an animal source serving as host than it is when derived from microbes derived from plate culture. Epidemiology is another important tool used to study disease in a population. For infectious diseases it helps to determine if a disease outbreak is sporadic (occasional occurrence), endemic (regular cases often occurring in a region), epidemic (an unusually high number of cases in a region), or pandemic (a global epidemic).
What is the causative spirochete of syphilis?
Answer: Treponema pallidum

Question: Judging by the historical records, by approximately 1000 AD the predominant ethnic group over much of modern European Russia, Ukraine and Belarus was the Eastern branch of the Slavs, speaking a closely related group of dialects. The political unification of this region into Kievan Rus' in about 880, from which modern Russia, Ukraine and Belarus trace their origins, established Old East Slavic as a literary and commercial language. It was soon followed by the adoption of Christianity in 988 and the introduction of the South Slavic Old Church Slavonic as the liturgical and official language. Borrowings and calques from Byzantine Greek began to enter the Old East Slavic and spoken dialects at this time, which in their turn modified the Old Church Slavonic as well.
Is there an answer to this question: When did Eastern Slavs become the dominant group in the area of Ukraine?

Answer: approximately 1000 AD

From 22 March through 26 March 1991, mass pro-democracy rallies and a nationwide strike was held in both urban and rural communities, which became known as les evenements ("the events") or the March Revolution. In Bamako, in response to mass demonstrations organized by university students and later joined by trade unionists and others, soldiers opened fire indiscriminately on the nonviolent demonstrators. Riots broke out briefly following the shootings. Barricades as well as roadblocks were erected and Traore declared a state of emergency and imposed a nightly curfew. Despite an estimated loss of 300 lives over the course of four days, nonviolent protesters continued to return to Bamako each day demanding the resignation of the dictatorial president and the implementation of democratic policies.
Who opened fire on violent demonstrators?
A:
unanswerable
