Explanation:
Subject-verb agreement errors usually happen the plural form of a verb is used when the singular form is required for the subject or when the singular form of the verb is used in a situation that needs the plural form to be used. In such case, the subject is said to disagree with the verb resulting in a subject-verb agreement error.
The sentence in the question should be rewritten as "Dancers from the movie Rize does continue to spread their inspirational message of hope to Los Angeles' South Central youth" in order to correct the subject-verb agreement.
Implicit means something not clearly stated, so implicit details are details that are not clearly stated. Or rather, they are details that are more implied, rather than given. And how they contribute to the story is that they make the reader figure things out, so it isn't just another easy story to read, but it is a little more difficult to read, because you have to figure things out. hope this answer helps :)
