Example Input: And as usual convoluted rules of engagement from this white house passed along through  the military they scorn, targeting low level direct US military combatants, no interest in winning by Obama, and this hospital having admitted and treated the terrorists fighters, what can you expect? And yes they did it to the soldiers in Vietnam as well.
Example Output: Yes

Example Input: Actually, McBeath retired (see "emeritus" in the story).  As it appears most folks who aren't Democratic insiders have long since forgotten about Scott McAdams, let me remind you that he was claiming to be "poor" when he and his wife were making around $150,000/year combined.  Oh, I know, "it's expensive to live in Sitka" yada yada...
Example Output: No

Example Input: Start making cash right now... Get more time with your family by doing jobs that only require for you to have a computer and an internet access and you can have that at your home. Start bringing up to $8012 a month. I've started this job and I've never been happier and now I am sharing it with you, so you can try it too. You can check it out here...
