Solution

Let's analyze the statements and conclusions one by one:

Statements:

  1. Some mice are keyboards.
  2. No keyboard is a key.
  3. All keys are rings.

Conclusions: I. Some rings are not keyboards. II. All mice being keys is a possibility.

Analysis: I. Since all keys are rings and no keyboard is a key, it is true that some rings (those that are keys) are not keyboards. II. Since some mice are keyboards and no keyboard is a key, it is not possible for all mice to be keys.

So, the answer is: Conclusion I is true. Conclusion II is false.
