Show the answer and explanation
CorrectNot quiteAnswer A
Correct answer: A
Explanation
Look at the ladders that are ropes. No rope is a bucket, so these ladders are not buckets. Some ladders are not buckets: I follows.
The other ladders, the ones that are not ropes, are free to be buckets. So 'No ladder is a bucket' is possible but not certain; II does not follow.
Only I follows.
Worth noting
Some + No gives 'Some … are not', never a full 'No'. The statements only control the ladders that are ropes.
