Subalterns differ in what aspect while sharing the same quality?

Explanation:
Subalterns are pairs of propositions that carry the same stance on the predicate (both affirmative or both negative) but differ in how much of the subject’s class they claim. The universal form says all of the subject are in the predicate, while the particular form says some of the subject are in the predicate. They refer to the same extension (the same set of things for the subject term), so the difference lies in quantity, not quality or extension. For example, All S are P and Some S are P share the affirmative quality but differ in quantity.
