Final answer:
Historical newspaper ads played a significant role in shaping public opinion and encouraging action, which could have provided Mary with important information and societal cues.
Step-by-step explanation:
In the context of Mary and the importance of information printed in newspaper ads, we see that historical newspaper ads played a crucial role in public communication and influencing public perception, particularly in times of conflict or political change. Ads and articles urged actions, such as pressuring men to enlist in war, and they informed citizens of ongoing events, such as those leading up to the American Revolution. While print media has seen a decline due to the rise of technology and social media, its historical impact remains evident in how it shaped public opinion and action. In Mary's case, such ads could have been helpful by providing information relevant to her time, encouraging community participation, or offering support through advertised products.
