Which of the following codes correctly represents the figure and mood of the…

CONCEPT

The mood of a categorical syllogism records the proposition types of the major premise, minor premise, and conclusion in that order: A is universal affirmative and E is universal negative.

The figure records the position of the middle term in the two premises; in figure III, the middle term is the subject of both premises.

APPLICATION

Let W denote warships, C commercial vessels, and N nuclear-powered submarines.

1. The conclusion is ‘No W are C’, so W is the minor term, C is the major term, and N—absent from the conclusion—is the middle term.

2. The major premise is ‘No N are C’: it has form E and layout M–P.

3. The minor premise is ‘All N are W’: it has form A and layout M–S.

4. The conclusion ‘No W are C’ has form E. The mood is therefore EAE, while M–P / M–S makes the figure III.

CROSS-CHECK / CONTRAST

Reading the original order around ‘so’ gives the same two premises and conclusion. The argument’s validity is separate from its figure-and-mood classification.

• EAE-IV has the same proposition-type sequence but figure IV requires P–M / M–S.

• AEE-III changes the major premise from universal negative to universal affirmative.

• EAE-III preserves E–A–E and places the middle term as subject in both premises.

• EEA-II changes the proposition-type sequence and uses P–M / S–M.

Result: the figure-and-mood code is EAE-III.
