Explanation:

27. A possessive pronoun indicates possession. For example, Whose pencil is this? 28. In this case, the word is feline because all the other options add some characteristics that the original word (cat) doesn't have. For example, tomcat is actually a cat, but is a male and domestic. Feline is a more formal way to refer to a cat without adding any other condition that we don't know if it has. 29. A reflexive pronoun is a word that ends in self or selves that is used when the subject and the object of the sentence are the same, for example I trust myself. The reflexive pronouns can be singular or plural, the singular reflexive pronoun in this case is yourself.
