Question

Select the answer that correctly inserts the clause into the blank in this sentence: Thomas Edison __________ lived and worked in New Jersey. *

Answer 1

Answer:

The correct answer is the third -Thomas Edison, who is best known for inventing the light bulb, lived and worked in New Jersey.

In this case, the noun phrase is followed by a clause which provides additional information about the noun phrase. This is a grammatical construction we refer to as apposition. Since the clause is embedded in this sentence, the rule is that it needs to be separated from the rest of the sentence by commas.
