Answer:
I didn't understand what the question meant exactly, but I'm assuming it's asking which word or words are used to convey a passage of time or to imply a sequence. So, I will answer each question based off of my understanding and give a short explanation for each.
1) immediately- because it signifies that something happened or is supposed to happen immediately after another event, implying a sequence. I would argue that when could also imply sequence because it specifies that after that exact moment something else will happen, but that's stretching it a bit, so don't quote me on it.
2) often- because it is a word that signifies a specific frequency that something may occur and implies a specific measure of time.
3) often- for the same reason as question 2.
4) Meanwhile- because it signifies that after a certain block of time, something else is happening and it implies a passage of time. I'm also unsure with this one but slowly could be an answer as well, because it implies a specific speed in which an event is occurring.
5) eventually- because it suggests that at some point in the near future, an event might have to occur, signifying a passage of time.
(Once again though, you might want to test slowly and when, to make sure they count, because I'm not entirely sure.)
