I think they do, but can someone tell me if these 3 sentences contain conjunctive adverbs:

Question

It is one thing to have a baseball card from that era; undoubtedly, to have the opportunity to see Wagner play, though, that would be a real treat for us both.
You and I, however, should get together very soon and talk about those times when we played baseball together when I was a kid; certainly, memories like those, they last forever. &
The past is a precious thing, you always told me to remember that; nonetheless, I feel like the future is just as important.

Answer 1

Yes. All three sentences contain conjunctive adverbs.
