Which answer best identifies the sentence fragment? The package is still on the front porch today. A house with no cars in the driveway. I have not seen the neighbors for a few days. I noticed a large package on my neighbor's front porch yesterday.

The answer is "A house with no cars in the driveway."

Explanation:

A sentence fragment is basically an incomplete sentence. That means it is a phrase that is missing a key element, such as a verb or a subject, or a phrase that is dependent on a main clause but has been detached from it through wrong punctuation.

The three following sentences presented in the question all possess the basic elements - subject, verb, and object or complement - and express a complete thought:

- The package is still on the front porch today.

- I have not seen the neighbors for a few days.

- I noticed a large package on my neighbor's front porch yesterday.

However, the fragment "A house with no cars in the driveway" is missing elements and, because of that, does not express a complete thought. Is the house the subject of a sentence? If so, where is the verb? Is it the object or the complement? What happened to the house? There are several questions we could ask, and none would be answered since we don't have the necessary information to do so. Below, some possibilities of full sentences are provided using the fragment above:

- I live at the end of the street, in a house with no cars in the driveway.

- While riding my bike, I passed by a house with no cars in the driveway. It was my friend Mike's home. By the looks of it, his parents weren't home.
