I am currently trying to write a persuasive essay in English about single payer healthcare. I'm trying to get more views and opinions from different people so I can be more informed. If any of you have an opinion on single payer healthcare please tell me- There is no judging or arguing here :)

i say that the right answer is: three personal subject pronouns. that’s because you will see “she” two times, referring to the librarian, and “they” one time, referring to the books. personal subject pronouns are used to replace common nouns or proper names.

the only possessive noun it’s present on the first sentence, when the speaker refers to “his” father.

i don’t know the story but to answer the fiest question about theme and   subject . theme is a debatable opinion about a subject while the subject is a topic the author deside's to stick with and use through out the book and in his/her writing
