Statements:
1. All tractors are machines.
2. Some machines are autonomous.
Conclusions:
I. Some tractors are autonomous.
II. Some machines are tractors.
Which of the conclusions logically follows?
Options:
(A) Only conclusion II follows
(B) Only conclusion I follows
(C) Both conclusions I and II follow
(D) Neither conclusion follows
Answer Key:
A
Step-by-Step Solution & Explanation
From 'All tractors are machines', the converse 'Some machines are tractors' immediately follows (Conclusion II). Since the middle term 'machines' is undistributed, no definite link between tractors and autonomous can be deduced, so Conclusion I does not necessarily follow.
