Why is the careful observation of the key sentence important in identifying the main idea of a paragraph

the careful observation of the key sentence is important cause it helps give u an idea of what your reading about and what the main focus is

Explanation:

The correct answer for the question that is being presented above is this one: "The key sentence should state what the rest of the paragraph is going to be about." The careful observation of the key sentence is important in identifying the main idea of a paragraph because it is will lead us what the paragraph is talking about.

the excerpt from chapter 2 of "animal farm", by george orwell that is an example of foreshadowing is "these three (snowball, napoleon, and squealer) had elaborated old major's teachings into a complete system of thought to which they gave the name of animalism." animal farm is an allegory of how czarist russia developed into communist russia with all its corruption. old major's teachings represent marx's theories turned into communism, animalism, by the three pigs. this foreshadows the oppression and corruption that will follow this revolt.

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.  

faulty coordination occurs when the writer gives equal importance two different ideas (clauses) which in fact are not equivalent. in order to correct a misplaced clause or idea, the writer can place less important or emphatic ideas in a relative clause as in the previous sentence.
