Question
Statements: Only a few Elements is Compounds.
Only a few Acids is Elements. No Acid is Neutral. Conclusions: I. Every Elements can be Acids. II. No Neutral is Compound. III. Some Elements are not Neutrals. In the question below there are three statements followed by three conclusions I, II and III. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions definitely follows from the three statements disregarding commonly known facts.Solution
Only a few Acids is Elements β All Elements may be Acids (A). Hence conclusion I follows. No Acid is Neutral (E) β Conversion β No Neutral is Acid (E) + Only a few Acids is Elements (I) β Some Elements are not Neutrals (O*) + Only a few Elements is Compounds (I) β No conclusion. Hence conclusion II does not follow but conclusion III follows.
