Two statements are given followed by conclusions. Assuming the statements to be true ,even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow ( s ) from the statements.

Statements:

I. All stones are chairs.

II. Some chairs are dogs.

Conclusions:

1. All dogs are stones.

2. At least some dogs are chairs.​​

I. All stones are chairs.

II. Some chairs are dogs.
