3 پرسش دربارهٔ آنچه شرح توضیح می‌دهد. با ۶ از ۱۰ یا بیشتر (دو ستاره) درس بعدی باز می‌شود.
پرسش 1
What does the second figure require in quality?
“In the second, the two must differ in quality and the major must be universal.” Its conclusions are therefore always negative.
پرسش 2
What can the third figure conclude?
With a minor that is affirmative and actual and one premise universal, the third figure yields a particular affirmative or a particular negative.
پرسش 3
Name one way, given in the Tahdhīb, of proving the moods of the fourth figure.
The fourth figure is shown by reductio, by reversing the order and then the conclusion, by converting both premises, or by reduction to the second or the third figure.
