I can help you with your grammar questions. It looks like you are asking about possessive adjectives and pronouns in English. Here is a brief explanation and the answers to your questions.

Possessive adjectives are words like my, your, his, her, its, our, and their. They are used before a noun to show who owns or has something. For example:

- This is my book. (The book belongs to me.) - She likes her job. (The job is hers.) - They live in their house. (The house is theirs.)

Possessive pronouns are words like mine, yours, his, hers, its, ours, and theirs. They are used instead of a noun to show who owns or has something. For example:

- This book is mine. (The book belongs to me.) - She likes her job. It is hers. (The job is hers.) - They live in their house. It is theirs. (The house is theirs.)

The answers to your questions are:

20. My brother is a teacher but hers is a doctor. (C) 21. Are these pencils yours? Yes, they are mine. (B)
