Correct Answer: Only conclusions I and III follow
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): All tuberculosis is curable – From the Venn diagram, it is evident that the circle representing tuberculosis lies inside the circle representing curable. So, from this, it can be concluded that all tuberculosis is curable. Thus, this conclusion follows. Conclusion (II): Some cancers are tuberculosis – From the Venn diagram, it is evident that there is no direct relation between cancer and tuberculosis. So, no definite relation can be drawn. Thus, this conclusion does not follow. Conclusion (III): All cancers are curable – From the Venn diagram, it is evident that the circle representing cancer lies inside the circle representing curable. So, from this, it can be concluded that all cancers are curable. Thus, this conclusion follows.
Therefore, only conclusions I and III follow. Hence, the second option is correct.
