The recent rise of low-cost airlines in Country Y has led to great increases in the number of air travelers and flights. However, a “hidden cost” of flying and certain other forms of travel is the significant amount of air pollution, which contributes to global warming. To make people pay these hidden costs—and in the process discourage the explosive growth in flying—the government of Country Y plans to impose fees on all air travel. There is a problem, however, in that many residents of Country Y would then use automobile transportation instead, without paying the hidden costs of the resulting air pollution.Which of the following additions to the government's plan would be likely to help most in overcoming the problem referred to in the final sentence above?
In order to improve the long-term savings rate of its citizens, Levaska’s government has decided to introduce special savings accounts. Citizens can save up to $3,000 a year in special accounts without having to pay tax on the interest, unless they withdraw money from the account before they reach the age of sixty-five. If they do withdraw any money before that age, they have to pay tax on the accumulated interest and a penalty.Which of the following, if true, most seriously threatens the success of the government’s plan?
Editor: Articles in Gardening Magazine often spur sales of the plants they describe, particularly among people new to gardening. Accordingly, we will no longer publish articles or accept advertisements praising the beauty of rare wildflowers. Most such plants sold to gardeners have been difficult to propagate under cultivation, so plant sellers often collect them in the wild. Our new policy is part of our efforts to halt this yearly plundering of our native plant populations.Which of the following, if true, casts the most doubt on the wisdom of the magazine's new policy as a way of pursuing the intended effect?
Fashion company executive: The number of competing brands of clothing is increasing much more quickly than is consumer demand for new clothing. As a result, it is becoming ever more for our clothing company to keep consumers focused on our products. To increase our sales, therefore, our company plans to introduce innovative, eye-catching lines of clothing much more frequently.To evaluate whether the plan described by the executive would be likely to achieve its goal, it would be most useful to know which of the following?
Trancorp currently transports all its goods to Burland Island by truck. The only bridge over the channel separating Burland from the mainland is congested, and trucks typically spend hours in traffic. Trains can reach the channel more quickly than trucks, and freight cars can be transported to Burland by barges that typically cross the channel in an hour. Therefore, to reduce shipping time, Trancorp plans to switch to trains and barges to transport goods to Burland.Which of the following would be most important to know in determining whether Trancorp's plan, if implemented, is likely to achieve its goal?
The country of Ertland has never imported apples in any significant quantity because consumers there generally prefer the unique texture of Ertland-grown apples. Nevertheless, apple growers from Kosolia, a neighboring country, plan to sell their apples in Ertland by selling Kosolia-grown apples at half the price of local apples and promoting them as a nourishing, low-cost alternative. Which of the following, if true, casts most doubt on the viability of the plan by Kosolia's apple growers to sell their apples in Ertland?
【OG18-P516-573题】The tulu, a popular ornamental plant, does not reproduce naturally, and is only bred and sold by specialized horticultural companies. Unfortunately, the tulu is easily devastated by a contagious fungal rot. The government ministry plans to reassure worried gardeners by requiring all tulu plants to be tested for fungal rot before being sold. However, infected plants less than 30 weeks old have generally not built up enough fungal rot in their systems to be detected reliably. And many tulu plants are sold before they are 24 weeks old.Which of the following, if performed by the government ministry, could logically be expected to overcome the problem with their plan to test for the fungal rot?
Given that employees of the XYZ Company could, in theory, do their work at home, the company developed a radical plan to increase efficiency: eliminate office-space expenditures by having employees work at home.

There were several volunteers; significantly, their productivity during this period was as high as or higher than before.Which of the following, if true, would argue most strongly against deciding, on the basis of the trial results, to implement the company’s plan?
