Global Thermostat!!

by Ozlemg » Sun Jul 17, 2011 12:35 am
66. Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation, acting as global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate the destruction of the ozone layer by reacting with chloroflurocarbons (CFC's).

A) acting as global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate
B)acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating
C)act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerating
D)they act as a global thermostat that thus keeps the Earth either from burning up or freezing over, even though it also accelerates
E)they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate


Could someone elaborate this question? A is the OA but imo "acting" coming after raditian forms ambiguity radiona or ice particles are acting!!! Need a help!
The more you suffer before the test, the less you will do so in the test! :)
