So, in the example "The fans in the stadium screamed loudly," the verb is ''screamed''. Asking the question, "Who screamed loudly?" gives the answer - and thus the subject: "The fans in the stadium". The predicate provides us with more information about the subject, in this case it tells us they "screamed loudly."
