However, both in English and Spanish, this is changing. You will see more and more the use of "actor" to signify male or female
Are there any general rules in Spanish for adding -s or -es when the noun is in plural form? Thanks.
in english, "the actors" could be feminine or masculine, so asking us to translate "the actors" into spanish, "las actrices" should also be marked correct.
If it's not used in the target language, then it should be marked wrong. We need to learn that it's incorrect to say some things - even if in English it would make sense
I disagree. "The actors" could mean "a group of female actors" in English. so asking us how to say "the actors" could be asking us to say "a group of female actors" or "a group of male/mixed gender actors". In which case either is correct.
I think you have a point. Suggest submiting your version the next time you see the problem then report it when you error out and select the choice saying that your answer should have been accepted.
