Which of the following technologies allowed explorers to determine their location by the position of the stars? a. the caravel b. the compass c. the astrolabe d. the telescope

The correct answer is C, the astrolabe.

Explanation:

The astrolabe is an astronomical instrument which allowed to determine the position above the horizon of stars and planets. The astrolabe was used primarily by navigators to determine their latitude given their current time.  With no other points of reference except for celestial bodies, the astrolabe helped sailors find their way while on high seas. By taking several measurements and triangulating them, these instruments helped navigators to determine their current location. Astrolabes were especially common during the Middle Ages and the Age of Exploration.

the answer would be logic.
