The correct answer is 2. “We’ll just have to figure out something else to do.” said Sam
Step-by-step explanation:
In literature, it is common dialogues are marked using quotation marks ("); in this case, the appropriate is to enclose the exact words of the character in quotation marks and add a punctuation mark if needed before the enclosing quotation mark. Besides this, a period should not be placed at the end of a quotation, except if the author does not add any information, and therefore a new sentence begins.
In the case of paragraph 2, there is a mistake in the punctuation of dialogues because a period is included before the closing quotation mark, despite new information is added and the sentence has not ended. Therefore, the correct would be to place a comma to add this detail as "We’ll just have to figure out something else to do,” said Sam.
