The correct answers are map making, compasses, and square sails .
Map making made significant progress during the Age of Exploration (when Europeans were sailing to Asia). Thanks to maps that accurately included North and South America and their separation from Asia, sailors were better able to navigate their way around the globe.
Compasses also helped tremendously. These devices helped sailors to find their bearings and assess what direction they were heading.
Lastly, square sails helped in the process of traveling from Europe to Asia. During this period, caravels became ships developed by the Portuguese. These easily movable ships often used square sails as a means to direct their boat.
