Step-by-step explanation:
Let's start with question 1: "She said, 'Where did you find it?'" The first step is to remove the quotation marks and add a comma after the word "said." The full sentence is "She said, 'Where did you find it?'" Now let's look at question 2: "You haven't heard this, have you?" There are two changes to make here. First, there should be a comma after "haven't." Second, the question mark should be replaced with a period. The full sentence is "You haven't heard this, have you?"
