In the nation of Malugia, the Secretary of Labor’s office released statistics indicating that last month, Malugia added 14,000 jobs in the tin refining industry, which in turn will supply many of Malugia’s manufacturing sectors. A large number of the new employees came from a variety of different service industries jobs that were lost over the past three years. The jobs growth came almost immediately after the national bond rate dropped, and the Secretary’s office attributes the new jobs directly to the lower bond rate: indeed, all three big tin refineries took out bonds to finance the new hirings. Economics professors at the national university, though, argue that the new bond rate was not the key reason that the new jobs were added.
Which of the following, if true, does most to help explain the economic professors’ doubt that the new bond rate was the primary cause of the new jobs?
A. Six months ago, the number one complaint among surveyed service industry workers was low wages, and employees in the tin refining industry earn much higher wages on average.
B. Two months ago, Malugia imposed new tariffs against Aplandia, blocking imports of cheaper Aplandian tin, which had been depressing the price of domestic tin.
C. Three members of the board that determines bond rates hold substantial holdings in the largest of the three tin refineries.
D. The Secretary of Labor’s office had been planning a number of stimulus packages to revive the tin refining industry, which had no substantial hires in the previous five years.
E. Over the past year, community colleges in Malugia offered people short-term, low-cost courses training people in all the necessary skills needed in the tin refining industry.
