Thanks!That's actually from a handout from my writing class. I am learning to describe statistical information. If you say so, I think it's just an unreal source of information. thanks.
I wouldn't call it "unreal" so much as unspecific. We do this often in English: We know that a particular institution must exist, but we don't know the exact name for it, so we call it by a descriptive name that explains what we mean.If you say so, I think it's just an unreal source of information. thanks.
