"Different cultures have different customs."
Translation:Diferentes culturas tienen diferentes costumbres.
I was curious too (since i put this and got it marked wrong) and looked this up and it is probably because diferente before a noun means "various" and after the noun means "different".
I put the same answer 9/11/18 and it was accepted. Duo showed their translation as 'another correct solution.'
Why is there no 'las' before 'culturas', and why are the adjectives before the nouns?
