Question
Statements:All funnels are flasks.No flask is a beaker.All funnels are test tubes.Conclusions: I. Some test tubes are not beakers.II. No funnel is a beaker.OptionsIf only conclusion I followsIf either conclusion I or conclusion II followsIf both conclusion I and conclusion II followsIf neither conclusion I nor conclusion II followsIf only conclusion II follows
Solution
The given statements are:
- All funnels are flasks.
- No flask is a beaker.
- All funnels are test tubes.
From these statements, we can infer the following:
- Since all funnels are flasks and no flask is a beaker, it follows that no funnel is a beaker. Therefore, conclusion II is correct.
- Since all funnels are test tubes and no funnel is a beaker, it follows that some test tubes (the ones that are funnels) are not beakers. Therefore, conclusion I is also correct.
So, the correct option is "If both conclusion I and conclusion II follows".
