Final answer:
The Kenderians suggest arming themselves and forming a strategic military defense to protect against threats. They advocate for physical defense, a strong leadership structure, and preparedness for warfare. Additionally, in case of a solar storm, measures like powering down grids can protect civilization.
Step-by-step explanation:
To protect themselves, the Kenderians suggest preparing for battle by arming warriors and forming a strategic military defence. First, they prepare weapons to protect the villagers, illustrating the need for immediate physical defense. Additionally, a council of aristocrats with their own troops and a strong army under a khan's control is formed to maintain internal peace and protect against external threats, as was done by the historical nomadic society led by Modun.
In the event of a large solar storm threatening civilization, protecting our technological infrastructure and electricity grids by powering them down or shielding them would be crucial to prevent widespread damage. The guardians in a society are also trained from a young age for strong character and courage, which is essential for reliable defense. Soldiers are well-equipped for travel and combat, as seen by their shields, spears, and helmets, indicating readiness for long-distance campaigns to battle. Lastly, the Kayapó tribespeople's cultural traditions also involve preparations for defending their lands.
