I wrote "Ona jsou zvířata" and that was accepted. I thought that ona had to accord with zvířata, i.e. it should be neuter. But apparently it has to have the gender of the word it refers to. So my sentence is correct if I refer to a neuter word (e.g. zvířata, prasata, kuřata)?
'oni jsou zvířata' Another puzzling rejection. If it is the sentence case capital, that is quite inconsistent with every other Duo exercise. So I report. Oops. The report options lack 'Accept my input'. Edit: in fact it is the missing full stop. Now, that is a new one.
