What custom did Natchez tribesmen volunteer for when their chief died?

Ritual sucide

Explanation:

The Natchez are a Native American people that lived in Mississippi before the colonists took the land. After some wars against the French they were dispersed with a large number sold into slavery by the French and most of the rest joining the Cherokee and Muscogee.

In times past they were ruled by the Great Sun and when he died, his wives were expected to commit sucide to be with him. Tribesmen would also volunteer to commit ritual sucide to be with him as well as it was considered to be a great honor to do so.

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.  

freedom of speech is also protected by the 1 amendment.

explanation:

here is pretty much what the 1st amendment says:

congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
