That underlined part is the wrong question... it should be, "and what are the things that must come to pass in quickness [noun] after the things WHICH ARE [/exist in the present]?" That's different from the question you're conveying, which I believe misses the point.
Kroogz had it, where he explained:
I believe when one CONFLATES the "in quickness [noun]" of verse 1 with that of the "near/soon [adverb]" issue of the other verses containing this word, only then can one come to the [incorrect] conclusion that the "after these things" things, had to have happened in the first century (the events surrounding 70ad, i.e. "soon" or "imminently" from when written).

And I've asked you a handful of times what was God's primary message in the book of Revelation. You haven't been considerate enough to give an answer. @Kroogz said it was about the rapture. Do you believe this too?
