Because scops (oral storytellers) were telling their stories orally and not from a written account, they needed something that would allow them to easily remember those stories. This why you notice that tales or epics that were first told orally have a certain cadence that makes it easier to follow. This allows the storyteller to remember and it also allows the reader to follow along in a better way.
As an interesting side note, these story tellers would also sometimes put the stories to music as that was another way to tell the stories. They would start as ballads and the storyteller would play a tune while they sang the stories.
The answer is the third one
1. Both the written and the unwritten laws keep the community and the society together. The written ones that are laws and the unwritten ones that are customs and traditions. To see if the written laws have been broken is what the courts need to establish, and not the unwritten ones.
2. Atticus then claims that no written laws were broken by neither Mayella nor Tom Robinson when they kissed. Mayella, in fact, is the one who broke the unwritten laws and codes and customs of Maycomb when she decided and kissed Tom Robinson. She kissed a black person, and that was her transgression according to society.
3. Because she kissed a black person she felt guilty. Her father would not have such "shame" befall their family and Atticus clearly states that it was her father who has beaten her because she broke the "code". Because of her guilt she decides to hide the fact that she wanted to and did kiss Tom she accused him of r.ape.
Because he writes from a different period in time and he uses words that we don't use so much anymore. He has different patterns and different iambic pentameter
