A sentence fragment is a group of words that does not convey a complete thought. Most likely, a sentence fragment is either missing a subject or predicate. The first line "Advertising in the local newspaper and online" is a fragment because it does not have a subject. It neglects to mention WHAT or WHO is advertising. The second line "The politician, whom I used to like, made many promises." This is a complete sentence because it has both a subject and predicate. The third line is "The candidates on television night and day" is a fragment because it is lacking a verb. The final line is a sentence because it has both a complete subject and predicate.
