If you're still wary, pick the most unremarkable one, that you think most people are likely to click. That way it seems more normal from their perspective -- you're just one among many in the wide sea. Here, I'll even help you out: https://secureweb.hqda.pentagon.mil/dpo/Details.asp?ID=108
Anyways add a ' to the end of that URL and you'll see clear evidence of a SQL injection bug. But it is just demonstrating that the bug is there. It would take more work to get access to their database.
This sentence makes no sense whatsoever. It seems that you think "unremarkable" means likely to draw a lot of attention.
