Final answer:
The statement about the Jewish community existing from around 200 BCE to 70 CE and being responsible for the Dead Sea Scrolls is correct, with carbon dating supporting the timelines of these ancient texts.
Step-by-step explanation:
The Jewish community that flourished from c.a. 200 BCE-70 CE and left behind many of the Dead Sea Scrolls is true. During this period, Jewish culture indeed thrived despite later periods of hardship. The scrolls themselves provide insight into the beliefs and practices of this community. Carbon-14 dating has verified these texts to be from around the timeframe of 100 BC to AD 50. Hence, this era was marked by significant Jewish presence and activity in regions surrounding the Dead Sea, and their remnants constitute some of the most important archaeological findings of Jewish history.
