Title: वैकल्पिक

Text: If P and Q are statements, then the statement "P and Q" is true if both P and Q are true and false otherwise. The statement "P or Q" is true in all cases except when both P and Q are false. An implication is a statement of the form "P implies Q" or "if P, then Q" (written symbolically as P -> Q). An implication is false if P is true and Q is false; it is true in all other cases. प्रत्येक पराग्राफले परीक्षण हुनेछ।
