While reasonable safety concerns may require changes in the building, the "beacon" promised by mr. libeskind cannot under any circumstances be replaced with a dreary, fear-inspired fortress. the tower could become overly bulky if extra security demands are simply grafted onto the present plan. it already calls for a massive building, with too much extra office space - added to suit the developer - and a very tall spire for those who want a perpetual sign of defiance to terrorists. nothing would better express capitulation to terrorism than a large skyscraper that looks like a vertical bunker. given the author’s tone, how do you think he feels about the security changes being made to the freedom tower? a. he is happy about the changes. b. he is unhappy about the changes. c. he is neutral about the changes. d. he believes the changes should be kept secret.
