History. "Marco Polo was the first to introduce the tasty..."
The answer is "informal and simple".
Which book.
First one, she impressed them with her amazing shot by shooting the apple, and it was unique because it was risky. She in a way, called them out for their lack of attention, which is an attitude few tributes have.
Second one wasn’t so unique because it was similar to peetas, but again she called them out for killing (no spoilers).
The term mimetic is associated with "imitation" so it might be said that during the 1800, literature tried to replicate or portray real life in the stories. that is to say, novels were based on realism so they were considered unique and a revelation because it was a new way of writing.
I haven't seen anything but cowardice and expediency.
