Person A found a old paper written in Arabic script in their basement. They took a picture of it and post it on a language forum.
Person B says: Do you have any relatives who used to live in an Arab country?
Person A: I don't think so.
The next comment reads:
Person B's question on whether you have relatives who used to live in an Arab country made me wonder if it could be the other way around, meaning perhaps someone who spoke a language that uses/used the Arabic script was living in the house.
Is using the present form of "have" correct here or should it be in the past?
