Answer:
The information that should be included in the summary is:
Spaniards came to the mountains in the mid-sixteenth century.
Ancient pottery and rock art have been found in the mountains.
The people who lived in the mountains were hunter-gatherers.
Evidence shows that the mountains were inhabited over 10,000 years ago.
Explanation:
A summary should be composed of the most relevant information that will help the reader to understand the main subject of the original text. Repetitive phrases, with little impact and information that are not relevant to understanding the subject such as "Many of the early residents lived in caves," can be omitted so that the text becomes smaller, but objective and more direct.
 
        
             
        
        
        
Answer:
The meaning is this, this boy was vexed by the horrible habit of smoking from the peer pressure of others. The author uses satire to jokingly tell of how much importance chewing tobacco was for a boy of his age. When Twain states " I was not able to learn to chew tobacco. I learned to smoke fairly well, but that did not conciliate anybody and I remained a poor thing, and characterless." he uses words such as "poor thing" and "characterless" to show humor within his writing. Though smoking and chewing tobacco isn't such a humorous subject, Twain uses a good amount of satire to represent comedy in such a serious topic. 
Explanation:
Mark Twain uses satire to show humor through his most serious topics. This brings the reader into the story with interest. 
 
        
             
        
        
        
It is false that the organization of a literary work is the central message or insight that it conveys.
This definition actually refers to the theme, not the organization of the text. Although sometimes organization can be quite important (usually in poems), in prose the theme or the plot are far more important.
