To write a persuasive essay, you need an argument. Your primary reason for wanting to go somewhere on summer vacation would be called your "thesis." Put your thesis in your introduction, and then elaborate on it. You basically need three reasons, one for each body paragraph, and conclude your argument in the final paragraph, the conclusion. Hope that helps!
Below I have bolded the parts of speech:
Jill bought a new dress for the party.
Jill (subject) bought (verb) a new dress (indirect object) for the party (direct object).
Answer: E. subject→verb→indirect object→direct object
Hope this helps!
If you could explain better maybe I could help.
