It depends on the context. Sometimes pure study is based on factual information and research, making it not purely fictional. But in some cases, it could be presented in a fictional way to make it more engaging.
Not really. Although folktales often have fictional elements like magic and mythical creatures, they can also have roots in historical events or cultural practices. For example, some folktales might be based on a real - life hero from a tribe, but as the story is told and retold, fictional aspects are added. So, not all folktales are pure fiction.
The Scooby - Doo gang is a great pure fiction team. Shaggy and Scooby are always there for comic relief but also have a knack for stumbling upon mysteries. Fred is the leader who comes up with plans, Daphne is brave and often gets into scrapes, and Velma is the brains of the group, solving the mysteries with her intelligence.
