Read this excerpt from The Great Fire. Schaffer's first signal went out at 9:30. Several minutes later, Schaffer realized his mistake and ordered Box 319 struck. This was still seven blocks away from the O'Learys', but close enough that firefighters could see the flames and alter their course. Unfortunately, Schaffer's young assistant, William J. Brown, stubbornly refused to strike Box 319, saying he was afraid it would confuse the situation. Brown was so stubborn about his decision that even after the fire he was able to write arrogantly in a letter that "I am still standing the watch that burned Chicago."

These errors had two fatal consequences. The most obvious was that a number of engines and dozens of firefighters were sent on a wild-goose chase and did not get to the fire for many minutes. More critical is that it kept fire companies located near De Koven Street in their stations. Several had seen the eerie, dancing glow beyond the rooftops near them and, even without official notice from Schaffer, prepared to respond. When they heard Box 342 rung, however, they assumed the fire was out of their territory and unhitched the horses. Only two fire companies were not fooled by the misleading alarm.

How does the structure of this excerpt illustrate the central idea that a series of individual mistakes contributed to the spread of the blaze?

A. by comparing and contrasting different people’s decisions and abilities

B. by comparing and contrasting the most effective firefighting techniques

C. by clearly explaining the reasons for the misleading alarm and its impact

D. by clearly explaining the reasons the fire started and the way it was put out

Read the passage from animal farm. as clover looked down the hillside her eyes filled with tears. if she could have spoken her thoughts, it would have been to say that this was not what they had aimed at when they had set themselves years ago to work for the overthrow of the human race. these scenes of terror and slaughter were not what they had looked forward to on that night when old major first stirred them to rebellion. if she herself had had any picture of the future, it had been of a society of animals set free from hunger and the whip, all equal, each working according to his capacity, the strong protecting the weak, as she had protected the lost brood of ducklings with her foreleg on the night of major's speech. instead—she did not know why—they had come to a time when no one dared speak his mind, when fierce, growling dogs roamed everywhere, and when you had to watch your comrades torn to pieces after confessing to shocking crimes. there was no thought of rebellion or disobedience in her mind. she knew that, even as things were, they were far better off than they had been in the days of jones, and that before all else it was needful to prevent the return of the human beings. whatever happened she would remain faithful, work hard, carry out the orders that were given to her, and accept the leadership of napoleon. but still, it was not for this that she and all the other animals had hoped and toiled. it was not for this that they had built the windmill and faced the bullets of jones's gun. such were her thoughts, though she lacked the words to express them. what was most likely orwell’s purpose for writing this passage? to show that clover is more sensitive to violence than the others to remind readers of major's speech and the original rebellion to present napoleon as a cruel leader unworthy of the animals’ support to represent misled followers and their dashed hopes for better lives
