Ar som popl born clvr, and othrs born stupid? Or is intllignc dvlopd by our nvironmnt or xprinc? Strangly nough, th answr to both qustions is ys.

On th on hand, if w tak two popl at random from th crowd, it is vry likly that thir dgrs of intllignc will b compltly diffrnt. Howvr, if w tak two idntical twins, chancs ar that thy will b as intllignt as ach othr. Thrfor, a conclusion can b drawn that intllignc is to som xtnt somthing w ar born with. Th closr th blood rlationship btwn two popl, th closr thy ar likly to b in intllignc.

On th othr hand, though, if w put two idntical twins in diffrnt nvironmnts, for xampl, w might snd on to univrsity and th othr to a factory whr th work is boring, w would find diffrncs in thir intllignc svral yars latr, which indicats that nvironmnt dos play a crucial rol in our intllignc.

Just as vry coin has two sids, our intllignc is partly born and partly dvlopd. Th sur way to dvlop our intllignc is intllignt parnts as wll as a good nvironmnt. (192 words)
