The mood of a categorical syllogism describes the types of categorical propositions that constitute the syllogism. In a standard-form categorical syllogism, the major premise, the minor premise, and the conclusion must all be standard-form categorical propositions. Hence, each of these statements can be identified according to the letters (A, E, I, and O) used to specify what type of categorical proposition it is. You can then describe the syllogism, as a whole, with a three-letter combination that lists the letters of the major premise, the minor premise, and the conclusion, respectively.

Examine each of the following standard-form categorical syllogisms. Determine which type of categorical proposition is represented by each of the syllogism's statements, and enter the identifying letter for each in the spaces provided. Then enter the three-letter combination that specifies the mood of the syllogism.

Example 1

Major Premise: No poultry are cattle.
Minor Premise: All animals on Old MacDonald's farm are poultry.
Conclusion: Some animals on Old MacDonald's farm are not cattle.
The major premise in Example 1 is an __ proposition.
The minor premise in Example 1 is an __ proposition.
The conclusion in Example 1 is an __ proposition.
Therefore, the mood of the categorical syllogism in Example 1 __ is.
