A letter to an editor has the purpose of putting forth a social issue or a problem that the writer of the letter wishes to be resolved, whether it be at a newspaper, or a magazine, and which may or may not be published by the media to which the editor belongs, depending on the exact objective of the letter and its usefulness. Because it is a formal letter, formal language must be used. As to the format used in these types of letters, this is the information that should always be added: 1. Senders address and contact information, 2. Date, 3. The editors contact information, including address, 4. The subject of the letter, 5. A Salutation, 6. A Body, 7. A closing statement that can also include compliments, and 8. Sender´s information, including signature and title if there is one. Given these characteristics mentioned above, the correct option, the one thing that cannot go inside the format of a letter to the editor is a caption (answer D) because a caption is literally a text that goes underneath a picture or photograph and has the purpose of explaining or giving further information on the picture. This is not the purpose of a letter to the editor and that is why it does not go in the format.
