correct answer is: OPTION b
Explanation: Let's analyze the given statements and conclusions step by step. The statements are: 1. Some animals are mouse. 2. No mouse is brown. The conclusions to evaluate are: I. Some animals are brown. II. No animals are brown. First, let's represent the statements logically:
- Statement 1: There exists at least one animal that is a mouse.
- Statement 2: All mice are not brown. Now, let's evaluate the conclusions: 1. Conclusion I: Some animals are brown.
- From the given statements, we know that some animals are mice, and no mice are brown. However, this does not provide information about other animals. It is possible that some animals (other than mice) are brown, but it is not certain. Therefore, we cannot definitively conclude that some animals are brown. 2. Conclusion II: No animals are brown.
- Similarly, we only know that mice are not brown. There is no information to suggest that all animals are mice or that no other animals are brown. Therefore, we cannot definitively conclude that no animals are brown. Since neither conclusion can be definitively drawn from the given statements, the correct answer is that either conclusion I or conclusion II follows, depending on additional assumptions not provided in the statements.

OPTION a: Incorrect. Only conclusion I does not follow because we cannot definitively conclude that some animals are brown.

OPTION b: Correct. Either conclusion I or conclusion II could follow, but not both.

OPTION c: Incorrect. Both conclusions cannot follow simultaneously.

OPTION d: Incorrect. Only conclusion II does not follow because we cannot definitively conclude that no animals are brown.
