                                Why did Europeans want a water route to India? (hint: Didn't they already have a land route? What was the disadvantage to a land route that a water route would solve?)
                                To travel by land from India, camels carried 100 pounds of silk, spices, and gold each while walking through the desert.  A ship route would result in over 600 pounds of merchandise at once, without relying on camel speed.
