I was in my son's English class (beginner) and there was a picture of a lobsters on it. The teacher wanted the kids to form a correct sentence using 'lobster(s)'. A kid said:
"These are the lobsters."
Was it correct? I feel like it sounds a little bit off because I'd often hear:
"These are lobsters"
instead, unless it's:
"These are the lobsters that we caught this morning"
or something. I'm not very knowledgeable when it comes to grammar, so I can only feel like it's off, but having no explanation whether or not it is wrong.
I'm not a native speaker, so kindly forgive me if my question is silly.
Thank you very much for your help!
