Which is the correct way to add information to the underlined portion of the sentence?

Ralph is coming with me to the concert and puppet show.
A
Ralph, my 2–year–old nephew, is coming

B
Ralph, my 2–year–old nephew is coming

C
Ralph my 2–year–old nephew, is coming

D
Ralph my 2–year–old nephew is coming

B

Ralph, my 2–year–old nephew is coming

The correct way to add information to the underlined portion of the sentence is option B: "Ralph, my 2-year-old nephew is coming."

To determine the correct way to add information to the underlined portion of the sentence, we need to consider the rules of punctuation and sentence structure. In this case, the underlined portion is meant to provide additional information about Ralph.

The correct answer is A: "Ralph, my 2-year-old nephew, is coming."

This choice uses a pair of commas around the phrase "my 2-year-old nephew" to set off the added information. The commas indicate that this information is not essential to the main sentence but provides extra details about Ralph. This is called an appositive phrase.

Option B does not include any punctuation to set off the additional information, making it incorrect.

Option C includes only one comma before "my 2-year-old nephew," which is not enough to properly separate the additional information from the rest of the sentence.

Option D also lacks any punctuation to set off the added information, making it incorrect as well.

Remember, when adding extra information to a sentence, use commas to set off that information and ensure clarity for the reader.
