Santora: the Steps This Organization Has Taken to Remedy Years

Santora: The steps this organization has taken to remedy years of discriminatory practices are clearly insufficient. Granted, there has been some progress in hiring entry-level personnel. The organization's first minority employees were hired one year ago. Still, there is not one minority anywhere in upper management. This failure clearly demonstrates the organization's lack of commitment to diversity.
Which of the following, if true, would weaken Santora's argument?
Upper-level managers often take new positions in other organizations.
Candidates for upper-level management positions are required to have at least three years of experience with the organization.
The company successfully recruited entry-level employees through traditional channels.
Upper-level managers are required to demonstrate capabilities in each of the four traditional management functions: planning, organizing, leading, and controlling.
The organization took steps to promote diversity only after settling a series of lawsuits.
