Statements:
1. No dog is a cat.
2. All cats are lions.
Conclusions:
I. No dog is a lion.
II. Some lions are not dogs.
Which conclusion(s) logically follow?
A. Only conclusion II follows
B. Both I and II follow
C. Only conclusion I follows
D. Neither I nor II follows
Answer: Option A
Solution (By JKExamLibrary)
All cats are lions, and no dog is a cat. This means dogs cannot enter the 'cat' portion of the 'lion' circle. Therefore, those lions which are cats are definitely not dogs (Conclusion II). However, dogs could still overlap with the non-cat portion of lions, so Conclusion I does not follow.

The company has launched a new smartphone with advanced AI features at an affordable price.
Conclusions:
