The Four Statement Types

Statement	Meaning
All A are B	A circle fully inside B circle
Some A are B	A and B circles overlap partially
No A is B	A and B circles completely separate
Some A are not B	At least one A lies outside B

Either-Or Case

When two conclusions form a complementary pair and neither follows alone, but together they cover every possibility — mark "Either I or II follows."

💡 Example: All pens are books. Some books are pencils. → "Some books are pens" follows (since every pen is a book); "Some pencils are pens" does not follow.
