Answer:
a. Palestine
Step-by-step explanation:
The Romans fought the Jews led by Simon Bar Kochba. They even managed to beat the Romans in an open fight that was unheard of at that time. This angered the Roman Empire because they had to devote so much manpower to fight such a small region in comparison. After they had won they banished almost all Jews, sacked the temple and renamed the city. The Jews didn't disappear entirely from the region but most of them were killed, enslaved or banished.
