Concept:Use the least possible Venn diagram to check logical conclusions from given statements.
Explanation:All land are ground means the land circle is completely inside the ground circle.
All big are land means the big circle is completely inside the land circle.
Only a few big are pond means some big are pond and some big are not pond.
So the pond circle overlaps only with a part of the big circle.
Thus, the overlapping part of pond lies inside big, land, and ground.
Hence, some ground (the part that contains pond) are pond – conclusion I is true.
Also, some pond (the same overlapping part) are land – conclusion II is true.
Since both conclusions are true, both follow.
Answer:Both conclusion I and II follow. (Option E)
