D. The end of English explorations in the New World.
Explanation:
Henry Hudson was an English explorer who embarked on four journeys to America. Hudson was tasked with finding a shorter route to Asia from Europe through the Arctic Ocean. The first two journeys were stopped by ice. During the third one, he sailed up the Hudson River. Finally, during his last voyage, he fell victim to a mutiny by his crew. Hudson's journeys are considered the end of English explorations in the New World.
The League of Nations issued a British mandate for Palestine—a document that gave Britain administrative control over the region, and included provisions for establishing a Jewish national homeland in Palestine—which went into effect in 1923.
