D: This summer, we are going on a road trip to Philadelphia, Pennsylvania, Baltimore, Maryland, and Rehoboth Beach, Delaware.
D: This summer, we are going on a road trip to Philadelphia, Pennsylvania, Baltimore, Maryland, and Rehoboth Beach, Delaware.
The sentence that requires semicolons instead of commas is:
D: This summer, we are going on a road trip to Philadelphia, Pennsylvania, Baltimore, Maryland, and Rehoboth Beach, Delaware.
The sentence that requires semicolons instead of commas is option D: "This summer, we are going on a road trip to Philadelphia, Pennsylvania, Baltimore, Maryland, and Rehoboth Beach, Delaware."
To determine whether to use commas or semicolons in a sentence, we need to consider the items being listed and their relationship to each other.
In option A, the sentence lists the places we will travel to on our summer road trip: Pennsylvania, Maryland, and Delaware. Because these are just a simple list of places, commas are appropriate.
In option B, the sentence lists the modes of transportation we will use on our summer road trip: car, train, and bus. Again, since these are just a simple list, commas work well.
Option C lists the cities we will visit on our road trip: Philadelphia, Baltimore, and Rehoboth Beach. Like the previous examples, this is a straightforward list, so commas are suitable.
However, in option D, the sentence is listing both cities and their corresponding states. To avoid confusion and ensure clarity, it is best to use semicolons instead of commas. By using semicolons, we can clearly separate each city-state pair: Philadelphia, Pennsylvania; Baltimore, Maryland; and Rehoboth Beach, Delaware.
So the correct answer is D: This summer, we are going on a road trip to Philadelphia, Pennsylvania; Baltimore, Maryland; and Rehoboth Beach, Delaware.
