Huh. Actaully, I wasn't confusing Islamic and Arabic; I just thought the Arabic population was much bigger. Only 3%? Really? *blinks*

I think I was just thrown off by the phrasing of the question. I wasn't sure whether they meant 'an Arabic country' as in its geographic location, the size of the ethnic group, or what. I'm still not entirely clear on what they're asking, though looking at a map I can see that Iran is farther off to the side of the Arabic peninsula than I pictured it. Oh well.
