Task: Explanation
Input (English): The Battle of the Boyne (Irish: "Cath na Bóinne" ] ) was a battle in 1690 between the forces of the deposed King James II of England, and those of Dutch Prince William of Orange who, with his wife Mary II (his cousin and James's daughter), had acceded to the Crowns of England and Scotland in 1688. The battle took place across the River Boyne near the town of Drogheda in the east of Ireland, and resulted in a victory for William. This turned the tide in James's failed attempt to regain the British crown and ultimately aided in ensuring the continued Protestant ascendancy in Ireland. Question: Who was the wife of the prince who was the victor of the battle that is celebrated in part by a series of parades known as "Orange walks"? Answer: Mary II
