Read the given statement(s) and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statement(s).

Statements:
All kings are bombs.
No parrots are kings.

Conclusions:
(I) Some bombs are not parrots.
(II) Some bombs are kings.

The correct answer is
Both conclusions (I) and (II) follow.

Statement Analysis

We are given two statements:

  • Statement 1: All kings are bombs.
  • Statement 2: No parrots are kings.

We need to determine if the conclusions logically follow from these statements.

Conclusion Evaluation

Conclusion (I): Some bombs are not parrots.

From Statement 1, we know that the set of 'kings' is entirely contained within the set of 'bombs'.

From Statement 2, we know that the set of 'kings' and the set of 'parrots' are completely separate (they have no members in common).

Since all kings are bombs, and no kings are parrots, it logically follows that the bombs which are kings cannot be parrots. Therefore, there exist bombs that are not parrots. Conclusion (I) follows.

Conclusion (II): Some bombs are kings.

Statement 1 states: "All kings are bombs."

Assuming that the category 'kings' is not empty (which is a standard logical convention for such problems), this statement directly implies that if something is a king, it is also a bomb.

Therefore, the set of kings is a subset of the set of bombs. This means there are bombs that are also kings. Conclusion (II) follows.

Final Decision

Both Conclusion (I) and Conclusion (II) logically follow from the given statements.
