(esos, esas) Being Dutch, Learning Spanish

I’m learning Spanish on my mobile (spaans 2)
There is a problem with the translation of the Dutch words: “deze” en “die”. In Dutch these words can be used for a single object or plural, so the translation in Spanish for “deze” can be “esto” or “estos” and the translation for “die” can be “eso” or “esos”.
So if memrise asks for a translation into Spanish from “deze” or “die” it has to be made clear whether the answer has to be plural or single; like it is now, you have a fifty percent chance of an error!
