•Incorrect Version:
–The purpose of the book persuades readers to get involvedin sports.
•In the sentence above, the subject is “purpose.”However, the purpose itself can’t “persuade,” as theverb in this sentence states.
•Correct Version:
–The author of the book persuades readers to get involvedin sports.
•In the revised sentence, the subject is “author,” and theverb is “persuades.” Because an author can attempt topersuade his or her readers, this sentence isgrammatically correct.
