Explanation:

First Question (Lateen sails were adapted from ______):

Lateen sails, a triangular sail design, were historically adapted from Arab merchant ships. African navies, Mongol technology, and Chinese treasure ships are not the primary source of lateen sail adaptation.

A sternpost rudder is a device used to steer ships. Its main function is to enable ships to maneuver (turn, navigate) more easily. Stronger hulls relate to ship construction, sailing in weak wind is about sail design, so the correct function is easier maneuvering.

An astrolabe is a navigational instrument used to determine latitude (and thus location) by measuring the angle of celestial bodies above the horizon. It's not for easy sailing, direction (a compass is for that), or ship strength. So it's most helpful in determining location.

Answer:

C. Arab merchant ships
