Explanation:
The sentences have possessive adjectives. In other words, they are pronouns followed by a noun. When we want to add a person's name in the sentence, we have to replace the possessive adjective with the name in brackets. Then we and add the 's, which is the genitive case.
For example, in the sentence These are her keys (Susan), the possessive adjective is her, and the noun that follows is keys, so we write Susan's instead of her. These are Susan's keys.
The possessive case and the genitive case both show possession. Another way to show possession is by writing the word of. To do so, we first identify the possessive pronoun and the noun. Then we change the possessive pronoun by the and, then we write of and the person. For example, In Its dinner is here, it becomes the dinner of the dog is here.
