Statement:
Only good singers are invited to the conference. Voice is a good singer.
Conclusions:
I. Voice is invited to the conference.
II. All invited people are good singers.
Which conclusion(s) logically follow?
Explanation:
The statement says 'only good singers are invited', which translates to 'All invited people are good singers' (II follows). However, it does not say *all* good singers are invited. Voice is a good singer, but might not be invited. Thus, I does not strictly follow.
Statements:
1. All cars are vehicles.
2. Some vehicles are not machines.
Conclusions:
I. Some cars are not machines.
II. All vehicles are cars.
Which conclusion(s) logically follow?
Explanation:
We know all cars are vehicles, but the vehicles that are not machines might be entirely outside the 'cars' circle. Therefore, Conclusion I is not definite. Conclusion II is a reverse of an 'All' statement, which is generally invalid. Neither follows.
