Attempts to blame the mayor's policies for the growing inequality of wages are misguided. The sharp growth in the gap in earnings between college and high school graduates in this city during the past decade resulted from overall technological trends that favored the skills of more educated workers. The mayor's response to this problem cannot be criticized, as it would hardly be reasonable to expect her to attempt to slow the forces of technology.

Which of the following, if true, casts the most serious doubt on the conclusion drawn in the last sentence in the passage?

(A)The mayor could have initiated policies that would have made it easier for less-educated workers to receive the education necessary for better-paying jobs.
(B) Rather than cutting the education budget, the mayor could have increased the amount of staff and funding devoted to locating employment for graduating high school seniors.
(C)The mayor could have attempted to generate more demand for products from industries that paid high blue-collar wages.
(D)Instead of reducing the tax rate on the wealthiest earners, the mayor could have ensured that they shouldered a greater share of the total tax burden.
(E)The mayor could have attempted to protect the earnings of city workers by instituting policies designed to reduce competition from foreign industries.
