Quizplus · Accepted Answer

The first premise states that no politicians are honest. This implies that all politicians are dishonest. 
The second premise states that some dishonest people are found out. This implies that only a subset of all dishonest people are found out, not necessarily including politicians. 
Therefore, the conclusion that some politicians are found out cannot be logically inferred from the given premises. The argument is invalid.
