"The bulls or the oxen?"

Translation: Taurii sau boii?

[vincemat]

Yeah boii

[xferguson]

Why can't we say "taurii ori boii" here? The one time I try ori instead of sau it doesn't work....

[backfrick]

For me the correct option was "Taurii ori boii?" and i'm confused on sau vs. ori. Are they used interchangeably?
