Problem: Bacteria were first observed by the Dutch microscopist Antonie van Leeuwenhoek in 1676, using a single-lens microscope of his own design. He then published his observations in a series of letters to the Royal Society of London. Bacteria were Leeuwenhoek's most remarkable microscopic discovery. They were just at the limit of what his simple lenses could make out and, in one of the most striking hiatuses in the history of science, no one else would see them again for over a century. Only then were his by-then-largely-forgotten observations of bacteria as opposed to his famous "animalcules" (spermatozoa) taken seriously.
How long did it take for his discovery to be taken seriously?
The answer is the following: over a century

Problem: The municipalities have two major policy responsibilities. First, they administer programs authorized by the federal or state government. Such programs typically relate to youth, schools, public health, and social assistance. Second, Article 28(2) of the Basic Law guarantees the municipalities "the right to regulate on their own responsibility all the affairs of the local community within the limits set by law." Under this broad statement of competence, local governments can justify a wide range of activities. For instance, many municipalities develop and expand the economic infrastructure of their communities through the development of industrial trading estates.
What is one way municipalities develop the economic infrastructure?
The answer is the following: development

Problem: Greeks from Cyprus have a similar history of emigration, usually to the English-speaking world because of the island's colonization by the British Empire. Waves of emigration followed the Turkish invasion of Cyprus in 1974, while the population decreased between mid-1974 and 1977 as a result of emigration, war losses, and a temporary decline in fertility. After the ethnic cleansing of a third of the Greek population of the island in 1974, there was also an increase in the number of Greek Cypriots leaving, especially for the Middle East, which contributed to a decrease in population that tapered off in the 1990s. Today more than two-thirds of the Greek population in Cyprus is urban.
Which colonial enterprise for land was the Greek Isles a part of
The answer is the following: British Empire

Problem: Similar examples abound. Macedonian, although mutually intelligible with Bulgarian, certain dialects of Serbian and to a lesser extent the rest of the South Slavic dialect continuum, is considered by Bulgarian linguists to be a Bulgarian dialect, in contrast with the contemporary international view and the view in the Republic of Macedonia, which regards it as a language in its own right. Nevertheless, before the establishment of a literary standard of Macedonian in 1944, in most sources in and out of Bulgaria before the Second World War, the southern Slavonic dialect continuum covering the area of today's Republic of Macedonia were referred to as Bulgarian dialects.
In what year was a Macedonian literary standard established?
The answer is the following:
1944
