Statements: Some wheels are rubber. All rubber is soft. Conclusions: I. Some wheels are soft. II. All soft things are wheels.
Correct answer: A. Only I
- A. Only I
- B. Only II
- C. Both
- D. None
Explanation
In logical deduction, we examine the provided statements and draw conclusions based on them. The statements given are: 'Some wheels are rubber' and 'All rubber is soft.' From these, we can infer that 'Some wheels are soft' because if some wheels are rubber and all rubber is soft, then some of those wheels must be soft. However, the conclusion 'All soft things are wheels' does not logically follow because there could be other soft things that are not wheels. Therefore, only conclusion I is correct.
