Comma as a support?

Hello @gregmat
You said in order to solve the 3rd blank, we should get ‘to’ which has come before ‘prevent’ as a clue for support. My question is: we have a comma a few words later after the 3rd blank. Can we use it as a support instead of ‘to’ and if the answer is no, why is that so? Would you please help me get this?

Thank you!

Yes, you can, although it does present a bit of a paradox or irony. If you have a formidable security apparatus, you SHOULDN’T be overthrown…of course the problem is if you make them so strong that they now have the power to overthrow you.

I still think it’s cleaner to focus on the “to.”

Thanks for yoyr reply.
That paradox you said is still there regardless of using either ‘to’ as a clues or the ‘,’ . Its just a nuance the sentence is pointing to.

Am I right, @gregmat ?

Yeah
