[填空题]Without that temporary working-site, the student___________________________________________(不可能按时完成设计).

[单项选择]The effect was temporary—temperatures started rising again after a year or so. But scientists began to wonder if the volcano hadn’t revealed a possible weapon against climate change. It takes only a back-of-the-envelope calculation to see that it would be possible to do artificially what the mountain did naturally. Ajudicious (明智的, 审慎的) application of sulfur dioxide (二氧化硫) to the upper atmosphere ,which could be accomplished by launching the gas from rockets, spraying it from high-altitude planes or releasing it from a big chimney, would have an almost immediate impact on temperature. And it would cost a thousand times less than even the most optimistic scenarios for cutting emissions. A small group of scientists began looking into how this kind of geo-engineering could be done most efficiently and with the fewest side effects.
Sulfur dioxide could be applied to the upper atmosphere in all the following ways EXCEPT
A. launching the gas from rockets.
B. releasing the gas from a big chirmley.
C. producing the gas from volcanoes.
D. spraying the gas from high-altitude planes.
