Which line in this excerpt from the still alarm by george s. kaufman demonstrates the use of understatement? ed (crosses up to r. window—peering out): it's reached the floor right underneath. bellboy: yes, sir. the lower part of the hotel is about gone, sir. bob (still looking out—looks up): still all right up above, though. (turns to boy) have they notified the fire department? bellboy: i wouldn't know, sir. i'm only the bellboy. bob: well, that's the thing to do, obviously—(nods head to each one as if the previous line was a bright idea)—notify the fire department. just call them up, give them the name of the hotel— ed: wait a minute. i can do better than that for you. (to the boy) ring through to the chief, and tell him that ed jamison told you to telephone him. (to bob) we went to school together, you know.
