Read the given statements and conclusions carefully. You have to assume the given statements to be true, even if they seem to be at variance with commonly known facts. Which of the given conclusions logically follow from the statements.
Statements: Some fish are whales. No whale is an octopus.
Conclusion (I): Some fish are octopuses.
Conclusion (II): Some whales are fish.
Only conclusion II follows
Draw Venn circles for the two statements. "Some fish are whales" means the fish and whale circles overlap. "No whale is an octopus" means the whale circle lies completely outside the octopus circle.
Conclusion (I): Some fish are octopuses. The overlapping part of fish and whales is excluded from octopuses, but the remaining fish may or may not touch octopuses. This is only a possibility, not a certainty, so it does not follow.
Conclusion (II): Some whales are fish. This is the valid conversion of the particular affirmative "Some fish are whales", so it necessarily follows.
Hence, the correct answer is Only conclusion II follows.
