1.Rhetorical construction,C选项Increase前面有太多adj,有点头重脚轻,不够简洁,没有E选项好
2.lies in的宾语应该是increase而不是consumer spending。D选项的表达导致产生一种含义,还有projected not to increase的spending,句意错误。
AB选项,and后面clause是完整句子,与"Scientists have identified an asteroid"平行,逻辑上不同
E选项,that后面不缺句子成分,但and that要与前面的定语从句平行,所以that也应该是引导定语从句,结构上有问题
D选项,but后面clause是完整句子,与"Scientists have identified an asteroid"平行,逻辑上不同
综上,算C选项
