Highlight the piece of evidence that best supports the claim. Claim: The chocolate chip cookie, first created in 1938 at the Toll House Inn, shows just how valuable word of mouth can be in making a new product popular.

During World War II, American soldiers from Massachusetts began to receive chocolate chip cookies in care packages. They shared the dessert with fellow soldiers who then quickly wrote home, asking their loved ones to ship batches of Toll House cookies. Ruth Graves Wakefield, the cookie's creator, started to receive tons of mail asking for the recipe, and she knew she would have to publish all the details in her next cookbook.​
