Consequently, the corporation plans to improve employee productivity by introducing new managerial techniques that delegate much of the decision-making to lower levels of the organizational hierarchy. Managers will simply set clear standards and guidelines and then allow employee teams to undertake tasks without centralized control.Which of the following, if true, would most strongly support a prediction that the Acme Corporation's plan will achieve its goal?

Thus, it is likely that many customers intending to buy our wine will mistakenly buy theirs instead. Danville Winery: Not so. The two bottles can be readily distinguished: the label on ours, but not on theirs, is gold colored. Which of the following, if true, most undermines Danville Winery's response?

An investigation revealed that over the past five years Harborville's public water supply has had a high level of pollutants.

In a certain wildlife park, park rangers are able to track the movements of many rhinoceroses because those animals wear radio collars. When, as often happens, a collar slips off, it is put back on. Putting a collar on a rhinoceros involves immobilizing the animal by shooting it with a tranquilizer dart. Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females. Probably, therefore, some substance in the tranquilizer inhibits fertility.Which of the following is an assumption on which the argument depends?
In preparation for a large-scale tree-planting project, Thomasville has recorded the location, species, and condition of every tree in its downtown area. The results will be compared with results of the last such tree census, taken 20 years ago.

The plan has good chances of success, since sweet potato is a staple of the region’s diet and agriculture, and the varieties currently grown contain little beta-carotene.Which of the following, if true, most strongly supports the prediction that the plan will succeed?
