Is it crucial for us to note that this situation is taking place on Earth, in the Milky Way galaxy, in time?

Ok I need the answers to this questions base on Letter From a Birmingham Jail by Martin Luther King Jr:1.Who is the Author?2.Who is the Audience?3What is the Form of the Text?4What is the Subject?5.What is the Context/Kairos?for this last question I’m including the text :Context: KairosAnd… a note about “context.”Context could be just about anything, so we have to focus on what is immediately relevant to a given rhetorical situation. For example, think back to our Metallica fan going into a job interview at a bank. There are many different ways to describe that particular rhetorical situation’s context. One might ask what city or state they’re in, since customs may differ from place to place. The kind of bank itself may matter as well; consider the difference in the way employees might dress at major international banks versus local credit unions. These would be relevant contextual details. Also consider details about the Metallica guy himself: why does he need a job? Is he looking for a permanent position (and, say, his life depends on it), or is he just looking for an informal summer gig unloading reams of paper? Obviously, details such as these would change our estimation of the guy’s “composition” (i.e. how he’s presented himself to the potential employer), and perhaps even in drastic ways. All of these potential contexts would be very relevant.There would be, however, details of context that were not so relevant to the composition. For example, is it crucial for us to note that this situation is taking place on Earth, in the Milky Way galaxy, in time? Those are legitimate aspects of this situation, but we don’t need to dwell on things that aren’t immediately relevant.We want to examine the context carefully and identify the environmental factors that are most relevant to the potential success of a text. The moment in time in which a particular text is able to make its mark is known as Kairos. According to Wikipedia, the Greeks had two words for time, Chronos and Kairos. In English, when things happen over a course of time, we refer to the events happening “chrono-logically.” Kairos, on the other hand, refers to a precise moment in time that allows for something of meaning to take place. It could be interpreted as a fancy way of talking about context. What characteristics of the environment surrounding the text were important in causing the text in the first place? How is the text effective as a result of certain environmental characteristics?
