nisam znao 6 i 9, a osmo je ekstra glupo formulisano...

10 opstih pitanja... Moze jako puno takvih pitanja da se nadje (koliko ima planeta u suncevom sistemu (ili da se nabroje), kada je poceo 2. svetki rat, kako se reflektuje svetlost do nasih ociju, zasto je severni pol zaledjen a drugi delovi zemlje ne, zasto nije isto vreme na svim delovima Zemlje,...nema kraja) ali ne moze se preko toga odrediti necije znanje. 10 pitanja da se odredi necije znanje........GLUPOST!!!
btw...niti godina traje 365 dana, niti dan 24h. Suvise neprecizno pitanje da bi se odlucivalo o necijem znanju.

Razlika izmedju prakse i teorije je mnogo veca u praksi nego u teoriji.

pobedio sam :)

mislim da su dobra pitanja i da ok pokazuju nivo obrazovanja. naravno da nisu definitivni pokazatelj, ali ovo bi trebalo svako da zna da odogovori.
