exotic or i'm stupid.?

OSN pre-selection is over. wow, the question so exotic.
number 1 until 3 is easy, but number 4 till the end, so difficulty -..-
the question doesn't standard, more difficult than the OSK, OSP, and OSN.
oh really not fair!
Really.? (please answer yes.!! o,,o)
oh Lord, make me wonder
so I can pass on that selection
and make my parents happy
just for it...
