Where to cite has nothing to do with my original argument (apart from anything else citeing at the end only is largely meaningless since you can't tell what is and isn't cited).
Your argument was that you had two sources which made it complicated to show which statements came from which. That is entirely about where to put the references. You can tell what is and what isn't cited by reading the sources.
You gave two examples, in both of which you said you had the sources, so why can't you cite them?
