Statements:
1. All tractors are machines.
2. Some machines are electric.
Conclusions:
I. Some tractors are electric.
II. Some machines are tractors.
Which of the conclusions logically follow(s)?
Options:
(A) Only conclusion I follows
(B) Only conclusion II follows
(C) Both conclusions I and II follow
(D) Neither conclusion follows
Answer Key:
B
Step-by-Step Solution & Explanation
- From Statement 1 ('All tractors are machines'), by conversion, 'Some machines are tractors' is unconditionally true (Conclusion II follows).
- However, Statement 2 only states that 'Some machines are electric', which does not necessarily overlap with the subset of machines that are tractors (Conclusion I does not necessarily follow).
