You are going to read four extracts which are all concerned in some way with art. For questions 19-26, choose the answer (A, B, C or D) which you think fits best according to the text.

19. The correct answer is C. The text describes the exhibition as a "charmingly idiosyncratic investigation" and notes that visitors are "left to have the pleasure of making connections and discoveries for themselves," which implies it is unpretentious and not overly guided by explanations. 20. The correct answer is B. The text states that the exhibition traces the history of an "almost forgotten aspect of the last 60 years," implying that kinetic art has not received the attention it deserves. 21. The correct answer is B. The first paragraph discusses Hockney's popularity, mentions his "engaging personality and the verbal wit that makes him such good copy for the newspapers," and then asks if this popularity negates the possibility that his art has a serious purpose. The writer is considering the possibility that his popularity might be the main reason for his fame (or at least a large contributor), rather than just his art. 22. The correct answer is C. The text states: "Hockney does not claim to be a great artist and is aware that only posterity can form a final judgement on his stature." This aligns with option C, as it indicates his view that his true value or final judgment will be determined in the future (by posterity).
