Question: Which continent, located almost entirely within the Northern and Western Hemispheres, did Thaddeus Radzilowski lecture in?

full_context: Document 1: Europe: Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. It comprises the westernmost part of Eurasia. Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary and amount to a historical and social construct. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundary with Asia.
Document 2: Arctic realm: The Arctic realm is one of the planet's twelve marine realms, as designated by the WWF and Nature Conservancy. It includes the coastal regions and continental shelves of the Arctic Ocean and adjacent seas, including the Arctic Archipelago, Hudson Bay, and the Labrador Sea of northern Canada, the seas surrounding Greenland, the northern and eastern coasts of Iceland, and the eastern Bering Sea.
Document 3: Arctic: The Arctic ( or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Northern Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost-containing tundra. Arctic seas contain seasonal sea ice in many places.
Document 4: North American Arctic: The North American Arctic comprises the northern portions of Alaska (USA), Northern Canada and Greenland. Major bodies of water include the Arctic Ocean, Hudson Bay, the Gulf of Alaska and North Atlantic Ocean. The western limit is the Seward Peninsula and the Bering Strait. The southern limit is the Arctic Circle latitude of 66° 33’N, which is the approximate limit of the midnight sun and the polar night.
Document 5: Thaddeus Radzilowski: Thaddeus C. Radzilowski or Tadeusz Radziłowski (born February 4, 1938 in Detroit) is an award-winning Polish-American historian, scholar, author, professor and co-founder of the Piast Institute, a national institute for Polish and Polish-American affairs. Dr. Radzilowski's work has focused on Poland and other Central and Eastern European nations, including Russia. He has written extensively on the histories of these regions as well as the migration of peoples from Central and Eastern Europe, with special emphasis on social history and historiography. He has lectured widely in Europe and North America and has published more than 100 monographs, edited collections, journal articles, book chapters and scholarly papers. In 1999, the President of Poland presented Dr. Radzilowski with the country’s high civil honor of the Order of Merit of the Republic of Poland for distinguished contributions to the dissemination of Polish culture in the world.

Document 7: North America: North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere; it is also considered by some to be a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea.
Document 8: Eurasia: Eurasia is a combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents (Europe & Asia). Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical social construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data.
Document 9: Territorial claims in the Arctic: The Arctic consists of land, internal waters, territorial seas, exclusive economic zones (EEZs) and high seas. All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the five Arctic coastal states: Canada, Norway, Russia, Denmark (via Greenland), and the United States. International law regulates this area as with other portions of the Earth.
