French New Wave/400 Blows

One of the most important filmmaking techniques used by New Wave filmmakers was the long take that tracks actions through an entire street scene or a prolonged running escape shot. Pick out two scenes in The 400 Blows where this technique is used. How does it contribute to the effectiveness of the scene? If you choose a street scene (set in Paris, for instance), what role do the long takes play in creating a sense of what Paris was like in the late 1950s?
