In the question below some statements are given followed by two conclusions I, and II. 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 conclusion definitely follows from the given statements, disregarding commonly known facts.
Statements:
All Spectacle are Lens.
Some Lens are Goggle.
Some Lens are Frame.
No Frame is Mirror.
Conclusions:
I. Some Goggle are Frame.
II. Some Lens are not Mirror.
III. Some Goggle are not Spectacle.
Some Lens are Goggle (I) → Conversion → Some Goggle are Lens (I) + Some Lens are Frame (I) → No conclusion. Hence conclusion I does not follow. Some Lens are Frame (I) + No Frame is Mirror (E) → Some Lens are not Mirror (O). Hence conclusion II follows. All Spectacle are Lens (A) + Some Lens are Goggle (I) → No conclusion. Hence conclusion III does not follow.
