Correct Answer: Only conclusions II and III follow
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion I: All supervisors are clerks – From the Venn diagram, it is evident that some parts of the circle representing supervisors lie outside the circle representing clerks while some lie inside. So, from this, it can be concluded that some supervisors are clerks. Therefore, this conclusion does not follow. Conclusion II: Some clerks are supervisors – From the Venn diagram, it is evident that the circle representing clerks completely lies inside the circle representing supervisors. So, from this, it can be concluded that all clerks are supervisors. Thus, if all clerks are supervisors, then some clerks will definitely be supervisors. So, this conclusion follows. Conclusion III: Some managers are clerks – From the Venn diagram, it is evident that some parts of the circle representing managers lie outside the circle representing clerks while some lie inside. So, from this, it can be concluded that some managers are clerks. Therefore, this conclusion follows. Conclusion IV: All superintendents are clerks – From the Venn diagram, it is evident that some parts of the circle representing superintendents lie outside the circle representing clerks while some lie inside. So, from this, it can be concluded that some superintendents are clerks. Therefore, this conclusion does not follow.
Therefore, only conclusions II and III follow. Hence, the second option is correct.
