题目内容：
阅读下列短文，从每篇短文后所给各题的四个选项（A、B、C和D）中，选出最佳选项，回答63至66题。A few years ago, paul Gerner began to gather a group of architects in Las vegas to ask them what it would take to design a public school that uschool that used 50 percent less energy ,cost much less to build and obviously improved student leaming .”I think half of then fell off their chairs ,” Gemer says.
Gemer manages scholl facilities (设施)for clark county, Nevada, a district roughly the siae of Massachusetts.By 2018,143,000 additional students will enter the already crowded public-education system. Gerner needs 73 new schools to house them. Four architecture teans have nearly finished designing primary school prototypes (样品) ; they plan to consruct their schools xtarting in 2009. The district will then assess how well the xchools perform, and three winners will copy those desiiigns in 50 to 70 new buildings.
Green schools are appearing all over , but in clark County, which stands out for its vastness,such aggressive targets are difficult because deign repuirements like more natural light for students go against the realities of a desert climate.”One of the biggest challenges is getting the right site orientation(朝向),” Mark McGinty, a director at SH Architecture, says.His firm recently completed a high school in Las Vegas. “You have the same building, same set of windows, but if its orientation is incorrect and it faces the sun, it will be really expensive to cool.”
Surprisingly, the man responsible for one of re most progressive green-design competitions has dorbts about ideas of eco-friendly buildings.”I don’t believe in the new green religion,” Gemer says.”Gemer says.”Some of the building technologies that you get are impractical. I’m interested in those that work.”But he wouldn’t mind if some green featrues inspire students. He says he hopes to set up green energy systens that allow them to liarn about the process of harvesting wind and solar power.”You never know what’s going to start the interest of achild to study math and science,”he says.
How did the architects react to Gerner’s design requirements?（ ）
A. They lost balance in excitement.
B. they showed strong disbelief.
C. they expressed little interest.
D. they burst into cheers.
