Final answer:
The correct action is to add a quotation mark before the word 'I' to indicate the beginning of Johnny's direct speech, resulting in: "I will be visiting my family in Atlanta, Georgia next week."
Step-by-step explanation:
The question relates to the correct usage of punctuation, specifically regarding quotation marks and comma placements. When integrating a quote into a sentence, it's essential to ensure the punctuation aids in the clarity of the structure and meaning. In the case of Johnny's statement, the correct answer is to add a quote before 'I' to properly delineate the beginning of the direct speech. This makes the sentence read: "I will be visiting my family in Atlanta, Georgia next week." The opening quotation mark before 'I' signifies that the sentence that follows is spoken directly by Johnny. Additionally, to adhere to the rule that commas go inside quotation marks, the comma after 'Atlanta' should be kept as part of the quote to separate the elements within the quotation.
