Question

Statements:
All cars are not trains.
All cars are four-wheeled vehicles.
Conclusions:
I. All trains are not four-wheeled vehicles.
II. Some trains are four-wheeled vehicles.

• A. If only conclusion I follows
• B. If only conclusion II follows
• C. If both the conclusions follow
• D. If neither I nor II follows

Answer 1

Answer: (A)

If only conclusion I follows

Answer 2

The correct option is (A):
Explanation: The first statement indicates that not all cars are trains, but it does not provide information about trains that allows us to conclude anything specific about their wheel count. Conclusion I asserts that all trains are not four-wheeled vehicles, which is a valid deduction since cars (four-wheeled vehicles) are excluded from being trains. However, conclusion II, which suggests that some trains could be four-wheeled vehicles, is not necessarily supported by the statements. Therefore, the correct answer is Option A – only conclusion I follows.
