Statements: All Star are Meteor. Some
Meteor are Comet. Only a few Constellation are Comet. Conclusions: I. All Comet can be Constellation II. Some Star are Comet. III. All Comet can never be Constellation. In the question below there are four statements followed by three conclusions I, II and III.
