Para-jumble (thinking without language): Reorder the sentences to contrast naming and reading failures with preserved conceptual play in chess. S1 = "The study of speech disorders due to brain injury suggests that patients can think without having adequate control over their language." S6 = "How they manage to do this we do not know." Between S1 and S6, arrange the clinical evidence in a revealing contrast: P = "But they succeed in playing games of chess." Q = "Some patients, for example, fail to find the names of objects presented to them." R = "They can even use the concepts needed for chess playing, though they are unable to express many of the concepts in ordinary language." S = "They even find it difficult to interpret long written notices." Choose the correct sequence of P–Q–R–S that completes the paragraph.
