Question
Three statements are given, followed by three
conclusions numbered I, II and III. 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: All Planet are Star No Star is Comet A few Meteor are Comet Conclusions: I. No Comet is Planet II. At least some Comet are Meteor III. Some Meteor are not StarSolution
All Planet are Star (A) + No Star is Comet (I) → No Planet is Comet (E) → Conversion → No Comet is Planet (E). Hence conclusion I follows. A few Meteor are Comet (I) → Conversion → Some Comet are Meteor (I). Hence conclusion II follows. A few Meteor are Comet (I) + [No Star is Comet (E) → Conversion → No Comet is Star (E) → Some Meteor are not Star. Hence conclusion III follows.
