I want to know the answer to the following question:
In what year was Diana  brought into the pomerium?
All the background I'm provided with is that "Greek deities were brought within the sacred pomerium: temples were dedicated to Juventas (Hebe) in 191 BC, Diana (Artemis) in 179 BC, Mars (Ares) in 138 BC), and to Bona Dea, equivalent to Fauna, the female counterpart of the rural Faunus, supplemented by the Greek goddess Damia.". Is that enough to answer the question?
Answer: yes
