Answer: The sentence fragments are "Advertising in the local newspaper and online" and "The candidates on television night and day". They can be rewritten as:
"Advertising in the local newspaper and online is very expensive"
"The candidates debate about economic measures on television night and day"
Step-by-step explanation: A sentence fragment is an incomplete sentence. In other words, a sentence fragment is a sentence that is considered to be incorrect because there is an important element missing. For example, "Advertising in the local newspaper and online" is a sentence fragment because it does not include the main verb. Moreover, in "The candidates on television night and day" the main verb is also missing. These two sentence fragments can be corrected by adding a main verb and modifiers. In that way, "Advertising in the local newspaper and online is very expensive" and "The candidates debate about economic measures on television night and day" are complete sentences.
