Answer:
Word of mouth
Social media
Step-by-step explanation:
An urban legend (also often called an urban myth or urban tale) is a story that is considered true as it spreads. It's usually told as something that has happened to a friend or family member, often with horrifying or humorous elements. A famous example of an urban legend is Bloody Mary.
Urban legends are spread by word of mouth - oral communication between people, and as the internet has become widely used, urban legends have begun spreading on social media, as well.
The point of historical lectures is to teach us about history (objective facts), while the purpose of political speeches is to make arguments for or against something that we might or might not do.
