Question
Five sentences related to a topic are given below. Four of them can be put together to form a meaningful and coherent paragraph. Identify the odd one out and key in the number of that sentence.
Sentences
Early-twentieth-century museums of natural history were organised on the conviction that arranging specimens by morphological similarity would make evolutionary relationships visible to any attentive observer.
This conviction reflected a faith, common to the period, that the right ordering of objects could
substitute for explicit theoretical commentary, which would have seemed didactic.
Visitors were therefore presented with rows of beetles and birds whose meaning, curators
believed, would be inferred from the very fact of their arrangement.
Modern museum design increasingly favours interactive screens that allow visitors to customise
the level of detail they encounter.
The implicit theory of viewing was that the eye, properly guided by sequence, would discover
relationships without being told what to find.
Detailed solution
Q20. Answer: 4. Sentences 1, 2, 3, and 5 form a coherent paragraph about early-twentieth-century museum theory: the conviction that arrangement could substitute for explicit theory (1, 2), the practical consequence (3), and the underlying theory of viewing (5). Sentence 4 is on the same broad theme (museum design) but shifts to modern interactive screens and visitor customisation, which belongs to a different stage of argument. The oddness is structural, not topical.
