Is this like 'teenage son' or 'the young people of this village or similar'?
"Where does your youth work?" Can youth not be plural? Or is that incorrect in this sentence?
youth used as a collective noun can be used with either single or plural form. So it would not be incorrect to say "the youth does", nor would it be incorrect to say "the youth do". Unfortunately this program has not been written as yet to such an intricate extent an still requires plural form verbs for collective nouns.
Wow, awesome streak when you posted this comment.
Where is your youth working is not entirely wrong, it just isn't used generally speaking. When using general terms you just say "where do your youth work, or where does your youth work" (either form is acceptable for collective nouns). You would say "where is...." more when speaking about something specific or current. Like, "what is going on with the youth these days"
When I did the exercise 2 years ago, my post above is what was accepted as the answer. I would not take issue with the answer accepted now: "Where do your young people work." (I am a native English speaker.)
My mistake. I don't know why but I thought you were asking a question. It's clear now you weren't.
