Some cups are spoons – From the Venn diagram, there is no definite relation between the circle of the cup and the spoon. Therefore, this conclusion does not follow.
Conclusion (II):
Some spoons are plates – From the Venn diagram, the circle of plates is completely inside the circle of spoons. So, some spoons are plates. Therefore, this conclusion follows.
