The passage states, 'However, the most important thing is not just superficial responses like tools and systems... It is the attitude of everyone... to reform their consciousness and proactively create a culture suitable for the new way of working that will be required.' This directly supports the correct answer. Wrong answer A is mentioned as a measure companies take, but the author calls it a 'superficial response' and not the most important thing. Wrong answer B mentions the advantages, not the solution to the problems. Wrong answer C describes a problem (loss of casual chats) but not the author's ultimate solution, which is a broader cultural and mindset shift.
