In a dialogue - replies?

[englishhobby]

Hello, everyone! It turned out to be a problem for me to translate into English from my native tongue the word meaning "a sentence or a few sentences that each speaker says in a dialogue". (I sometimes need to denote not just one sentence, but all the sentences said by one speaker in his part). I wouldn't call all of them replies, because sometimes they are initial phrases, not replies. So which word should I use if I want to give directions to my students of this sort:

Put the ______________ in the dialogue into the correct order.
Here's a sample jumbled dialogue:
- Yes, I like these trousers. Do you have them in size 42? - how should I call this?
- Well, it wouldn’t matter too much. Can I try them on?
- Can I help you, sir?
- Of course. The changing rooms are over there.
- Just a minute, sir. I am afraid this is the last pair. We have the same trousers in Size 42, but in a different colour. They are grey, not black.


P.S. I don't need to rephrase the above sentence, I just need the right word to fit in.
Thank you in advance.

Sorry for boosting my post , but I still hope someone will help me with this problem.

I would just put "Put this dialogue in the right order" or "The lines in this dialogue have been mixed up. Rearrange them so that they make sense".

I would just write:

"Put the lines of dialogue in the correct order."
