Hello. It is not possible to answer your question because it is not possible to hear the sentences that Felix is hearing on his cell phone. However, I will try to help you in the best possible way.
To answer that question, you need to know what pronouns are. In general, pronouns are the words the words that relate to the nouns of the sentences determining the gender, degree and number of that noun. To answer your question, you must listen to the nouns of the sentences (which are the words that name something or someone) and understand the pronoun that best suits that noun and the context of the sentence. Examples of pronouns are: me, you, him, she, it, us, me, mine, yours, hers, hers, ours, myself, yourself, herself, himself, ourselves, themselves, yourselves, this, that, that, someone, nobody, none, any, who, other, among others.
