Some politicians are honest. All honest people are truthful. Which of the following conclusions necessarily follows?
Correct: B
From 'Some P are H' and 'All H are T', we can conclude 'Some P are T' by the chain rule. Since some politicians are honest and all honest people are truthful, those same politicians are also truthful. This is a valid conclusion (DAR-1 in figure 1). The other options either reverse the universal premise or make unsupported claims.
