"They are..." vs. "these are" when answering the question "What are these...?"
When asked, "What are these called in English?" or similar, should we use just the right pronoun or can we also answer with the right demonstrative pronoun? For example, which is grammatical or preferred: "They are chopsticks" or "These are chopsticks"?
Although "These are ..." would be preferred to match the question, I would use "They are ..." since the item(s) in question (in most of the cases) will not be close enough for me to refer them with "these".
