Example Input: The African Great Lakes region, which Kenya is a part of, has been inhabited by humans since the Lower Paleolithic period. By the first millennium AD, the Bantu expansion had reached the area from West-Central Africa. The borders of the modern state consequently comprise the crossroads of the Niger-Congo, Nilo-Saharan and Afroasiatic areas of the continent, representing most major ethnolinguistic groups found in Africa. Bantu and Nilotic populations together constitute around 97% of the nation's residents. European and Arab presence in coastal Mombasa dates to the Early Modern period; European exploration of the interior began in the 19th century. The British Empire established the East Africa Protectorate in 1895, which starting in 1920 gave way to the Kenya Colony. Kenya obtained independence in December 1963. Following a referendum in August 2010 and adoption of a new constitution, Kenya is now divided into 47 semi-autonomous counties, governed by elected governors.
Example Output: How long has the African Great Lakes region been inhabited?

Example Input: As soon as the Greek War of Independence broke out in 1821, several Greek Cypriots left for Greece to join the Greek forces. In response, the Ottoman governor of Cyprus arrested and executed 486 prominent Greek Cypriots, including the Archbishop of Cyprus, Kyprianos and four other bishops. In 1828, modern Greece's first president Ioannis Kapodistrias called for union of Cyprus with Greece, and numerous minor uprisings took place. Reaction to Ottoman misrule led to uprisings by both Greek and Turkish Cypriots, although none were successful. After centuries of neglect by the Turks, the unrelenting poverty of most of the people, and the ever-present tax collectors fuelled Greek nationalism, and by the 20th century idea of enosis, or union, with newly independent Greece was firmly rooted among Greek Cypriots.
Example Output:
What year did the Greek war of independence break out?
