Answer :
In the sentence "Carl Sagan himself wrote that document," the pronoun "himself" is a reflexive pronoun.
Here's why:
1. Reflexive pronouns are used when the subject and the object of a sentence refer to the same person or thing. In this case, the subject "Carl Sagan" is the same as the object referred to by "himself."
2. The pronoun "himself" reflects back to the subject "Carl Sagan," emphasizing that he personally wrote the document.
3. Examples of reflexive pronouns include: myself, yourself, himself, herself, itself, ourselves, yourselves, themselves.
Therefore, in this sentence, "himself" is a reflexive pronoun because it refers back to the subject "Carl Sagan" in a way that shows the action was done by the same person being referred to.
