Directions (1-5): Read both the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts. Give answer— (1) if only conclusion I is true. (2) if only conclusion II is true. (3) if either conclusion I or conclusion II is true. (4) if neither conclusion I nor conclusion II is true (5) if both conclusions I and II are true.Solution
 Alternate solution:  Some glasses are not tables(O) `->`  I.I `->`  No conclusion. Hence conclusion I does not follow.  All doors are chairs(A) `->`  Conversion `->`  Some chairs are doors(I). Hence conclusion II does not follow.
