Lines 265–267: What tone does King create through his word choices in these lines? What effect does this shift in tone have on King’s audience?

King's choice of words allows for a humble tone, which makes the audience see him as peaceful, friendly and gentle.

Explanation:

This question is about "Letter from Birmingham Jail".

In lines 265-267, we can see that King uses a standard language, but very humble and apologetic, with the use of popular words and is easily understandable. This creates a very beneficial effect on King, because he shows him as someone who is not interested in appearing elite and academic, but he shows him as an ordinary, friendly, suffering and meek man.

This kind of diction comes to King's supporters who see him as a great example and can even touch those who disapprove of him by showing that King is being polite and peaceful in his claims.

explanation:

21 balloons is the story of professor william sherman's travels.

in 1883, he set off from san francisco for a balloon ride over the pacific and was found a month later floating with 21 balloons in the atlantic ocean. this seemed an astounding feat and everyone wanted to know what had happened.    

professor sherman was loyal, however, and said he would tell his tale first to the western american explorers club in san francisco, of which he was a member. this built up suspense for several chapters before he began to tell of the wonders of his adventures and the amazing island of krakatoa, an island which had just been blown up by a volcano.  

the residents of krakatoa are all millionaires who live under a "gourmet government" of their own devising. we get to see all the incredible adventures that creative people with unlimited resources would create according to the author.
