Answer explanation

Here's an example of an acceptable response:

Ruth Wakefield’s mistake led to the invention of the chocolate chip cookie. She was in a hurry and didn’t have time to melt the chocolate like the recipe said. Instead, she broke the chocolate into chunks and mixed them into the dough. When the cookies came out of the oven, the chocolate hadn’t melted all the way. Even though she thought they were ruined, the cookies tasted really good. Her guests liked them too, and that’s how chocolate chip cookies were invented by accident.
