54. Can you explain the role of Introduction in one sentence?

The single-sentence rule for understanding research paper Introductions.   Have you thought about what the Introduction section of a life-science paper really does?   

In this episode, we will address that question and discuss a simple rule.   We will share a single sentence that encapsulates the entire role of the Introduction.   It will make it easy to grasp the authors' intention and the paper’s core logic.    

Hint: it is related to the key trio in the Abstract: the "Background-Known-Unknown" trio from Episode #53.
