___________________________________________________________.For instance, 19th-century Japan was a world where steam and sail, railroads and rickshaws all shared common space. Industrial revolutions were distributed unequally in place and time. In the Second World War, the most common transport for the German army wasn’t tanks and other motorized vehicles but horses. The technological world wasn’t flat. This is the world, still, today. It is lumpy and bumpy, with old and new technologies accumulating on top of and beside each other. Choose the option which fits in best in the given blank:
The paragraph describes 19th century Japan and Second World War Germany to highlight the fact that technological change results in a “lumpy and bumpy” world where old and new technologies co-exist, piling on top of each other. This idea is best captured by option (B). Technologies layer and stack and endure over time. Option (A) talks of factors other than “efficiency” driving technological change. This is unrelated to the rest of the paragraph. Option (C) states that “the best ideas” do not necessarily become popular right away. The paragraph does not describe any “great ideas” and say that these were unpopular when they were first introduced. Option (D) states that innovations do not spread at the same rate; some are adopted slowly while some catch on quickly. The paragraph given, however, does not relate to this idea. Correct Answer: Choice (b)
