Here is a situation:
A: Hey, who is that girl? The one with the blue backpack. B: She is Susan, the daughter of Mr. Norman.
In this case, should Susan be the only daughter of Mr. Norman or she could have her sister? Or either is possible?
My guess is either is possible; the former is possible because literally that sounds like he has only one daughter, and the later is also okay considering the situation where Susan is the daughter of Mr. Norman that is being mentioned in the dialogue
Thanks in advance for any comments!
