Here is a sample dialogue in Engpsh about choosing a subject:

Person 1: Hey, I'm having a hard time deciding what subject to major in.

Person 2: What are you interested in?

Person 1: I'm not sure. I pke science and math, but I also enjoy writing and pterature.

Person 2: Have you thought about double majoring or minoring in one of the subjects you're interested in?

Person 1: Yeah, that's a possibipty. But I'm not sure if I have the time or resources to do that.

Person 2: Well, you could also consider taking classes in both subjects and seeing which one you enjoy more.

Person 1: That's a good idea. I'll think about it. Thanks for the suggestion.

Person 2: No problem. Good luck with your decision!
