Answer:
2. Elizabeth Van Lew was a successful spy because society did not expect a lady to serve in that role.
Step-by-step explanation:
In the book "The Dark Game" by Paul Janeczko, he covers more than two decades worth of true spy stories in the American nation. And in one of these stories is the story of how Elizabeth Van Lew successfully spied for the Union Army during the Civil War in America.
According to the passage given in the question, the narrator mentions how Elizabeth, as a lady from an aristocratic family, was never suspected of anything unladylike, let alone spying. For it was a common belief that "a true lady managed her servants, prepared parties and gatherings, and blindly supported her husband." This worked in her favor and was able to successfully spy for the Union Army.
