Answer :
The correct answers are A) The Italians had a monopoly on Mediterranean trade. D) Ottoman Turks had captured Constantinople. E) Extremely high prices were caused by the difficulty of moving Eastern goods to Europe. F) Ships traveling water routes could carry more goods.
These were the reasons why Europeans wanted an all-water route to the Orient.
Europeans wanted to find new trade routes and reach to Orient lands to establish commerce alliances with other regions. They wanted to break the monopoly Italians had in the Mediterranean Sea. Things became more complicated when the Ottomans defeated the Byzantine Empire and captured the capital city of Constantinople. Europeans knew that goods transportation through ships was an efficient way to transport more products.
