Such researchers are dedicated advocates for the particularities of any policy they draft, so they tend to overlook any method of analysis that may undermine it.

Which of the following, if true, best accounts for the typical policy development practices among major political parties?

To keep depleted batteries from polluting the environment, the government of Ulm is discussing a mandate that would require residents to dispose of them through a special pickup service.

When driving with headlights on at their normal setting, cars equipped with High-Intensity Discharge (HID) headlights emit extremely bright light that far exceeds the amount normally required for driving at night and can temporarily blind other drivers.

Fast food industry representative: Many people blame fast food alone for the rise in obesity in the United States over the past thirty years. Yet clearly, sedentary lifestyles have also played a major role in this trend.

In the fast food industry representative’s argument, the portion in boldface plays which of the following roles?
