Answer:
This ancient group of people lived in the Bronze Age.
Step-by-step explanation:
If you look at the passage, you are looking to find a sentence that simply summerizes who the Celts were.
In the sentence that I found, it told us in just a couple of words many facts that tell us a lot.
"This ancient group of people lived in the Bronze Age."
From that sentence we know that the Celts were:
- Ancient
- A group of people
- They lived and formed during the Bronze Age
I really hope this helped!
