Certainly! Let's break down the sentences and clarify the use of "their," "theirs," "her," "hers," "our," "ours," "your," and "yours" in each context.

1. It's (their / theirs) door. - "Their" is the correct choice here. So the sentence should be: "It's their door."

2. They're new pupils, and I don't know (their / theirs) names. - "Their" is the correct choice here. So the sentence should be: "They're new pupils, and I don't know their names."

3. (My / Mine) flat is bigger than (her / hers). - "My" is the correct choice here. So the sentence should be: "My flat is bigger than hers."

4. They took (our / ours) books, and we took (their / theirs). - "Our" is the correct choice here. So the sentence should be: "They took our books, and we took theirs."

5. Are these pencils (her / hers)? - "Hers" is the correct choice here. So the sentence should be: "Are these pencils hers?"

6. Is this (your / yours) house or (their / theirs)? - "Yours" is the correct choice here. So the sentence should be: "Is this your house or theirs?"

7. It's (theirs / their) problem, not (our / ours). - "Theirs" and "ours" are both correct. So the sentence could be: "It's theirs problem, not ours."

8. Is it (yours / your) article about spiders? - "Yours" is the correct choice here. So the sentence should be: "Is it your article about spiders?"

9. - No, it's not (my / mine). - "Mine" is the correct choice here. So the sentence should be: "No, it's not mine."

10. We know (their / theirs) address, but they don't know (our / ours). - "Their" and "ours" are both correct. So the sentence could be: "We know their address, but they don't know ours."
