I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Pockets of Georgian architecture survived the war, but much of the city was levelled. There has been extensive redevelopment since World War II. Increasing traffic congestion in the 1920s led to partial demolition of medieval walls around the Bargate in 1932 and 1938. However a large portion of those walls remain."?
What specifically was wrong with the city that it needed redevelopment?
