Question: There is no single definition of an "aircraft carrier", and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, and sometimes as distinct types of naval aviation-capable ships. Aircraft carriers may be classified according to the type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope, former head of the Royal Navy, has said that "To put it simply, countries that aspire to strategic international influence have aircraft carriers".
Is there an answer to this question: What is the definition of an "aircraft carrier"?

Answer: There is no single definition

Question: Slavs are the largest Indo-European ethno-linguistic group in Europe. They inhabit Central Europe, Eastern Europe, Southeast Europe, North Asia and Central Asia. Slavs speak Indo-European Slavic languages and share, to varying degrees, some cultural traits and historical backgrounds. From the early 6th century they spread to inhabit most of Central and Eastern Europe and Southeast Europe, whilst Slavic mercenaries fighting for the Byzantines and Arabs settled Asia Minor and even as far as Syria. The East Slavs colonised Siberia and Central Asia.[better source needed] Presently over half of Europe's territory is inhabited by Slavic-speaking communities, but every Slavic ethnicity has emigrated to other continents.
Is there an answer to this question: What did Slavic mercenaries colonise?

Answer: unanswerable


Question: In 1941, Zuse followed his earlier machine up with the Z3, the world's first working electromechanical programmable, fully automatic digital computer. The Z3 was built with 2000 relays, implementing a 22 bit word length that operated at a clock frequency of about 5–10 Hz. Program code was supplied on punched film while data could be stored in 64 words of memory or supplied from the keyboard. It was quite similar to modern machines in some respects, pioneering numerous advances such as floating point numbers. Replacement of the hard-to-implement decimal system (used in Charles Babbage's earlier design) by the simpler binary system meant that Zuse's machines were easier to build and potentially more reliable, given the technologies available at that time. The Z3 was Turing complete.
Is there an answer to this question: What did the Z3 operate for a clock frequency?

Answer:
about 5–10 Hz
