How to differentiate long paraphrasing and original ideas with APA in-text citations? Let's say I have the following paragraph:


  Smith (2011) contends that blah blah blah.  Blah blah blah blah blah blah blah.  blah blah blah blah blah blah blah blah.  This allows for one to decide that monkeys are actually fish.


Everything in blahs is paraphrased from Smith (2011), but the conclusion that monkeys are actually fish is my own idea.  How do I mark where Smith's ideas end and my ideas start?
Use a conditional construction to indicate distance from the cited claim.  E.g., 


  Smith (2011) contends that blah blah blah. Blah blah blah blah blah blah blah. blah blah blah blah blah blah blah blah. If Smith's contention were true, it would follow that monkeys are actually fish.
