How to determine the complexity of fiction and non-fiction text?

You can look for elements like made-up characters, settings, and events that aren't based on real life. If it's full of imagination and creativity, chances are it's fiction.

You can look at the genre labels or descriptions. If it's labeled as 'novel' or 'fantasy,' it's likely fiction. If it's labeled as 'biography' or 'history,' it's probably non-fiction.

One way to determine a non-fiction book is by looking at the subject matter. If it's based on real events, facts, or provides educational or informative content, it's likely non-fiction.

You can look at the themes explored, the character development, and the overall message the author seems to be conveying.

Look at the source material. Since it's about a real person, J. Robert Oppenheimer, and a well - documented historical event (the Manhattan Project), it's non - fiction.

You can look at the elements like made-up characters, fantastical settings, or events that seem unlikely in real life. If these are present, it's likely fiction.

We need to consider the purpose of the text. If we think the Book of Genesis was written to convey spiritual and moral lessons rather than a scientific or historical account in the modern sense, then we can't simply label it as fiction or non - fiction. It's a complex text that has been interpreted in many ways over time. In a religious community, it's often regarded as non - fiction for its religious significance, while from a scientific perspective, its accounts don't match up with established scientific knowledge.

Look at the cover and blurb. If it has a picture of a made - up scene or characters, and the blurb mentions things like 'a world of fantasy' or 'a fictional journey', it's likely fiction. If it has something related to medical, scientific, or real - life events regarding heartbeats, it might be non - fiction.

The fact that it has a fictional narrative arc with made - up characters going through various fictional events within the framework of historical events makes it fiction. It's not a historical account in the sense of non - fiction. Tolstoy uses his creativity to tell a story that may be inspired by history but is not a pure retelling of facts, so it's fiction.

Well, you can start by looking at the topic of the book. If it's about history, it might appeal to history buffs. If it's a self-help book on fitness, then fitness enthusiasts could be the target.
