This is a given example when I looked up "insofar" in a dict app. I don't know what exactly the origin is, since it doesn't matter anyway, I guess. The bolded part are those I find hardly comprehensible. Please help me restate the whole sentence into that I can readily understand.
With respect to the source: I'm sorry I really dont know, all that I can tell is that it is an randomly given example from an app"English dictionary--livio" when I searched word "insofar".
If someone does know about it, that would be very nice of you to help me edit and add the source to it as a matter of convenience.
