Directions: After reading Chapter 2, do the following activities, which focus on recognizing whether the conditions for statements and opinions are sufficient.
Learning About Thinking
A condition is a thing on which something else depends. For example, sunlight is a condition for growing plants. A sufficient condition is a condition that, by itself, is enough to make something happen or to make a statement true. For example, in many classes, getting caught cheating on a test is a sufficient condition for failing the test.
To see whether or not a condition is a sufficient condition, use this formula: If the "If A, then B" statement is true, then the condition is sufficient. For example, let the statement "you buy a ticket to the basketball game" be A, and let the statement, "you may watch the game in person" be B." Your statement will be: If you buy a ticket to the basketball game, then you may watch the game in person.
Buying a ticket to the game is a sufficient condition for watching it in person. Now consider a statement in which the condition is not sufficient. Let A be "if you study hard for a test," and let B be "you will get a good grade." Your statement will be: If you study hard for a test, you will get a good grade.
Usually studying hard will produce a good test grade. Still, other factors enter into what type of grade you will receive. Your aptitude for the subject, your knowledge of what is to be covered by the test, and even your mood while taking the test can affect your grade. You could say that just studying hard is not always sufficient for producing a good grade. The condition is not sufficient for the validity of the statement that follows.
Thinking About the Novel
Sometimes statements seem to be true until you challenge the conditions upon which they are based. Statements cannot be correct if the basic conditions are not sufficient.
A. Consider the following statements from the novel. After each statement, condition A is suggest. Use the formula "If A, then B" to decide if the condition is sufficient for a valid statement. Give reasons for your decisions.
1. "The work of teaching and organizing the others fell naturally upon the pigs, who were generally recognized as being the cleverest of the animals."
Let A be: The pigs are the cleverest of the animals.
Statement:
Is the condition sufficient to make the statement correct? Why or why not?
2. "Some of the animals talked of the duty of loyalty to Mr. Jones, whom they referred to as 'Master,' or made elementary remarks such as 'Mr. Jones feeds us. If he were gone, we should starve to death.'"
Let A be "Mr. Jones feeds the animals."
Statement:
Is the condition sufficient to make the statement correct? Why or why not?
3. Mollie "had taken a piece of blue ribbon from Mrs. Jones's dressing table, and was holding it against her shoulder and admiring herself in the glass in a very foolish manner. The others reproached her sharply, and they went outside."
Let A be: Animals should not behave in any way like humans. Statement:
Is the condition sufficient to make the statement correct? Why or why not?
Can You Prove That?
B. The Seven Dommandments indicate that animals should have nothing to do with humans. Think od a sufficient condition that would make such a statement valid. Present your condition in the If A, then B formula by filling in the blank below.
If _______________________________ then animals should have nothing to do with humans.
Writing About the Novel.
Think of a statement about the relationship between animals and humans that is correct based on what you have read so far in Animal Farm. Form an If A, then B statement about the relationship and argue for its truth in a paragraph. Be sure to use examples from the novel to back up your argument.
