South Slavic historically formed a dialect continuum, i.e. each dialect has some similarities with the neighboring one, and differences grow with distance. However, migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans have caused large-scale population displacement that broke the dialect continuum into many geographical pockets. Migrations in the 20th century, primarily caused by urbanization and wars, also contributed to the reduction of dialectal differences.
Contrary to the 16th and 18th centuries, what caused migrations in the 20th century?
A: urbanization and wars

FBI records show that 85% of COINTELPRO resources targeted groups and individuals that the FBI deemed "subversive", including communist and socialist organizations; organizations and individuals associated with the Civil Rights Movement, including Martin Luther King, Jr. and others associated with the Southern Christian Leadership Conference, the National Association for the Advancement of Colored People, and the Congress of Racial Equality and other civil rights organizations; black nationalist groups; the American Indian Movement; a broad range of organizations labeled "New Left", including Students for a Democratic Society and the Weathermen; almost all groups protesting the Vietnam War, as well as individual student demonstrators with no group affiliation; the National Lawyers Guild; organizations and individuals associated with the women's rights movement; nationalist groups such as those seeking independence for Puerto Rico, United Ireland, and Cuban exile movements including Orlando Bosch's Cuban Power and the Cuban Nationalist Movement.

The responsibility for military command remained with the British Crown-in-Council, with a commander-in-chief for North America stationed at Halifax until the final withdrawal of British Army and Royal Navy units from that city in 1906. Thereafter, the Royal Canadian Navy was formed, and, with the advent of military aviation, the Royal Canadian Air Force. These forces were organised under the Department of Militia and Defence, and split into the Permanent and Non-Permanent Active Militiasfrequently shortened to simply The Militia. By 1923, the department was merged into the Department of National Defence, but land forces in Canada were not referred to as the Canadian Army until November 1940.
What responsibility remained with a commander-in-chief for North America?
A: unanswerable

The British Isles lie at the juncture of several regions with past episodes of tectonic mountain building. These orogenic belts form a complex geology that records a huge and varied span of Earth's history. Of particular note was the Caledonian Orogeny during the Ordovician Period, c. 488444 Ma and early Silurian period, when the craton Baltica collided with the terrane Avalonia to form the mountains and hills in northern Britain and Ireland. Baltica formed roughly the northwestern half of Ireland and Scotland. Further collisions caused the Variscan orogeny in the Devonian and Carboniferous periods, forming the hills of Munster, southwest England, and southern Wales. Over the last 500 million years the land that forms the islands has drifted northwest from around 30S, crossing the equator around 370 million years ago to reach its present northern latitude.
Avalonia formed the northwestern half of Ireland and what other country?
A:
unanswerable
