Answer:
seek new trade routes to East Asia.
Explanation:
After Byzantine Empire fell in the hands of Ottomans, the trade links between Europe and East were interrupted. Therefore, Portuguese and Spanish sailors decided to find a water route to East India.
Their first idea was to sail around Africa and to reach India. That was the idea of Portuguese, while Spaniards believed that by sailing towards the west they will reach eastern shores of Asia.
These two protestant churches believed that you shouldn’t have to visit the church to determine if you will go to heaven or hell in the afterlife, but they believed in predestination and faith that does not rely on how often you visit church, which persuaded the poor (the majority of europe) to convert to these churches. this defied the anglican’s belief that if you’re a good person and visit church consistently, heaven will be rewarded and not that your whole
life is planned out for you, which is what the protestants thought.
