Ex.1. Statement –

Any hotel is not a house.

Conclusion – I. Some hotels are houses.

                        II. Some poles are hotels.

Ans.:

We can see from the diagrams that house is not related to any of the objects here. Some of pole & hotels are covered with each other’s regions, so all the poles are hotels. So, some hotels are poles.

Only conclusion II is the logical answer from the above diagrams.

If the conclusion comes out of the graph, then all contain the conclusion.

      All fruits are roots.

      All trees are roots.

But the given statement is not included in the logical conclusion.
