The question given below contains three elements. These elements may or may not have some inter linkage. Each group of elements may fit into one of these diagrams at (A), (B), (C), (D) and/or (E). You have to indicate the group of elements which correctly fits into the diagrams. Which of the following diagrams indicates the best relation between Examination, Questions and Practice?

In 'best relation' Venn-diagram questions, first turn the sentence that classifies how the three given terms relate into standard set relationships: 'All A are B' places circle A entirely inside circle B; 'Some A are B' means circles A and B partly overlap without either fully containing the other; and 'A and B are different from each other' (or 'no A is B') means circles A and B do not touch at all. The diagram that reproduces every one of these pairwise relationships simultaneously is the correct answer.
The standard classification for these three terms is: some questions are asked in examination and some in practice, but examination and practice are different from each other. Applying the rule above: Questions and Examination must partly overlap (some, not all, questions are exam questions); Questions and Practice must partly overlap (some, not all, questions are practice questions); and Examination and Practice must not overlap at all (they are different from each other).
The layout where one term sits fully nested inside another, with the third term completely separate, would require total containment for one pair and zero connection for the other pair -- stronger than, and different from, 'some ... but different'.
The layout with all three terms fully separate from each other would mean no term shares anything with any other term -- but the classification gives two explicit partial overlaps, so total separation is too weak a fit.
The layout with one large circle fully containing two smaller, mutually exclusive circles would require every examination-related item and every practice-related item to belong entirely to the third category -- an 'all' relationship, not the 'some' relationship the classification states.
Only the diagram with three circles arranged in a chain -- the middle circle overlapping each of the two outer circles in turn, while the two outer circles do not overlap each other -- reproduces both required partial overlaps and the one required separation, and this matches the standard published explanation for this exact question.
