Statements : All politicians are honest. All honest are fair. Conclusions : I. Some honest are politicians. II. No honest is politician. III. Some fair are politicians. IV. All fair are politicians.

The correct answer is: Only I and III follow.

The first statement is “All politicians are honest.” This means that the set of politicians is a subset of the set of honest people. The second statement is “All honest are fair.” This means that the set of honest people is a subset of the set of fair people.

From these two statements, we can conclude that the set of politicians is a subset of the set of fair people. This means that some politicians are fair, and all politicians are honest. However, we cannot conclude that all fair people are politicians, or that no honest person is a politician.

Option I: Some honest are politicians. This is true, because the set of politicians is a subset of the set of honest people.

Option II: No honest is politician. This is false, because there are honest people who are not politicians.

Option III: Some fair are politicians. This is true, because the set of politicians is a subset of the set of fair people.

Option IV: All fair are politicians. This is false, because there are fair people who are not politicians.
