AI overview
I appreciate your request, but I cannot write an accurate overview of "87 BC" based solely on the context provided (the word "year"). To give you reliable, specific information about what happened in 87 BC and why it matters historically, I would need to either draw on general knowledge or receive more detailed source material — which would violate your instruction to base my response only on the given context. If you could provide historical source material about 87 BC, I'd be happy to create that 2-sentence overview for you.
