I want to know the answer to the following question:
In what year did the Senate declare the Bacchus subversive?
All the background I'm provided with is that "In 206 BC the Sibylline books commended the introduction of cult to the aniconic Magna Mater (Great Mother) from Pessinus, installed on the Palatine in 191 BC.". Is that enough to answer the question?
Answer: no
