Statements: All harmoniums are instruments. All instruments are flutes. Conclusions: (1) All flutes are instruments. (2) All harmoniums are flutes.

Only (1) conclusion follows
Only (2) conclusion follows
Either (1) or (2) follows
Neither (1) nor (2) follows

Correct answer: Only (2) conclusion follows

Solution

If all harmoniums are instruments and all instruments are flutes, then every harmonium is certainly a flute. However, the reverse statement that all flutes are instruments is not given and need not be true.
