Answer :
This sentence is correct as it is because it includes the correct tense.
What is this sentence about?
The sentence refers to a tribe and it describes a historical process of the tribe.
Is the sentence correct?
Considering the sentence refers to an event of the past the use of the verb "roamed" is correct. Indeed, this is the only one that is correct as the words roam, did roam, etc. do not show the grammatically correct use of the simple past tense.
Note: This question is incomplete because the original sentence is missing; here is the missing sentence:
- This powerful tribe then roamed over the whole extent of the Mississippi valley, between that river and the Rockies.
