Correct option is A
Argument:
All advocates of high tariffs (A) are Republicans (R).
Some Republicans (R) are not conservatives (C).
∴ Some conservatives (C) are not advocates of high tariffs (A).
Step 1: Identify Terms
Major Term (P)= Predicate of conclusion =advocates of high tariffs (A)
Minor Term (S)= Subject of conclusion =conservatives (C)
Middle Term (M)= Term in both premises but not conclusion =Republicans (R)
Step 2: Rewrite in Standard Form
Premise 1:All A are R →All P are M(A-type)
Premise 2:Some R are not C →Some M are not S(O-type)
Conclusion:Some C are not A →Some S are not P(O-type)
Mood:AOO
Step 3: Determine Figure
Check theposition of the middle term (M = R):
Premise 1 (All P are M):M is thepredicate.
Premise 2 (Some M are not S):M is thesubject.
This fitsFigure IV(middle term is predicate in Premise 1 and subject in Premise 2).
(Mood = AOO, Figure = IV → AOO-IV
