Final answer:
Henry VIII arranged for the Act of Supremacy to secure his position and obtain a male heir.
Step-by-step explanation:
The reason why Henry VIII arranged for parliament to pass the Act of Supremacy during the English Reformation was because he needed a son as his successor and had to divorce his wife who was unable to bear children. The Act of Supremacy established Henry VIII as the Supreme Head of the Church of England, granting him the power to control religious affairs in the country. By separating from the Catholic Church and divorcing his wife, Henry VIII sought to secure his position and ensure a male heir for the English throne.
