To strengthen Melissa's thesis statement about the importance of codebreaking as discussed in both "The Dark Game" and "The Code Book," she could add the main ideas of each book. This addition would provide a clearer understanding of how each book contributes to the overall theme of codebreaking. For example:
1. "The Dark Game" focuses on the historical significance of codebreaking during wartime, highlighting the critical role it played in shaping the outcomes of key battles.
2. "The Code Book" delves into the evolution of codes and ciphers throughout history, emphasizing their impact on communication and security.
By including the main ideas of each book, Melissa can further emphasize the significance of codebreaking as explored in both texts, thereby strengthening her thesis statement.
