Tom: Hi, Alex! I'm sorry I'm late again. I lost my keys. I thought: "They are not in my bag, so they [can't|must|might] be somewhere in the apartment". And I was right! I needed some time to check all the house, so…
Alex: OK, don't worry. I'm happy you solved your problem. Now we can discuss our project about technology. I don't know for sure, but I believe that robots [must|can't|might] replace humans in the future. Let's write about it!
Tom: Of course, it [must|could|may] be, but I do not think it is likely. This sounds too futuristic and utopian. There are some professions that can't be mastered by artificial intelligence.
Alex: Well, that's why I'm not sure. It could be, or it [couldn't|must|might]... Right, your suggestions?
Tom: I think the problem of fatal diseases [could|must|may not] be solved in the future. We have so many medications and tools, so that's for sure! Why don't we opt for writing about this?
Alex: You are absolutely right, Tom. I can't agree with you more. I even know a cool website where we [may|could|can't] find all the necessary information. Unless there are some technical issues, it is very likely that we'll find some good articles there!
