1. The condition no < 11 will get evaluated only if age > 18 evaluates to False.
2. The condition no < 11 will get evaluated if age > 18 evaluates to True.
3. The statement a = 25 will get evaluated if any one one of the two conditions is True.
4. || is known as a short circuiting logical operator.
5. The statement a = 25 will get evaluated only if both the conditions are True.
