Example: Percy and Annabeth enjoy swimming in the canoe lake at camp.
"and"
This is S because the sentence is talking about Percy and Annabeth, who are the subjects. "and" is the word that combines the subjects.
Your key words here are, But, And, Or, Yet, ext. These are words that combine. If any of these words are in between two names that sentence is S. If any of these words are in between any other words, it is P.
I hope I was able to answer your question and you understand what to do now! :) Best of luck!
Oh, don't forget to put parenthesis around the But, And, Or, Yet, ext. type of words! :)
