In the question below are given four statements followed by four conclusions numbered I, II, III and IV. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts. Statements: Some chairs are tables. Some beds are sofas. No chair is a sofa. No bed is a table. Conclusions: I. It is possible that a bed is a chair. II. It is possible that some sofas are tables. III. Some chairs are sofa. IV. All tables are chairs.

Conclusions:
I. It is possible that a bed is a chair → The possibility is true.
II. It is possible that some sofas are tables → The possibility is true.
III. Some chairs are sofa → Not possible, hence False.
IV. All tables are chairs → False (it is possible but not definite true)
Thus, only conclusion I and II follows.
