A选项的this指代不清 B选项的it也指代不清 E选项的动词形式有问题 最后剩下C，D两个选项徘徊，听了老师以前的音频，还是不太明白两点，第一点是：音频中C选项错误的地方是因为鸟儿是主语，所以不能推动政府，但是D选项的主语也是鸟儿。第二点是：C选项和D选项的一个差异点是时态。C选项是过去完成时态，是发生在过去的过去，可以这样理解么，“鸟儿在它弄下来之前被打败了”如果这样理解的话，这个时态不就没有错了么？

Brochure:  Help conserve our city's water supply.  By converting the landscaping in your yard to a water-conserving landscape, you can greatly reduce your outdoor water use.  A water-conserving landscape is natural and attractive, and it also saves you money.

Which of the following, if true, provides the best basis for a rebuttal of the criticism?
