Conclusions:
I. Some ponds are round. → False (it is possible but not definite)
II. Some mountains are square. → True (Some ponds are mountains and All ponds are square → Some mountains are square)
III. Some ponds are both mountains and round. → False (it is possible but not definite)
IV. Some stools are square. → False (it is possible but not definite)
Hence, only conclusion II follows.
