Answer:
O Warrior Horseman
Explanation:
The Mongols had great military strengths and abilities. Their culture was such that at an early age, the young boys were trained in the use of horses. Horses were respected by the Mongols. When the young boys got to the teenage age of fifteen where they were now regarded as adults, they joined the military forces and had access to horses for battle.
Their culture was such that they were predominantly Warrior Horsemen. They also used implements like spears, swords, and arrows for battle. This culture of theirs is a likely reason why the Mongols did not develop guns.
