The correct answer is D. She put a message inside an empty eggshell
Explanation:
In the case of writing a summary of Elizabeth Van Lew's role as a spymaster or any summary about the life of someone and their role related to some specifc issue, you need to include those details that key and that support the main theme. In the case of Elizabeth' role as a spymaster the fact that she uses messages in empty eggshells, supports the main theme and allow you to develop further ideas in the summary, especially related to her role as a spy. This can be explained as this detail supports her role as a spy, considering Elizabeth used different methods or techniques to get confidential information or transmitting that information to others, including visiting soldiers in prison, inventing a code to send information to the Union generals and <u>putting messages inside empty eggshells</u> so this messages could not be discovered. Other options are not correct as any other person could be born in 1818, use her/ his house as a safe home or send three messages weekly without being a spy.
