Due to His Spouse's Accepting a Promotion, Colin Had Recently

Due to his spouse's accepting a promotion, Colin had recently left his private sector job in Kansas and accepted a new position in the public service with the state of Ohio. The change had been quite a shock at first. The organizational cultures were quite different, and each environment offered a different set of challenges. One new challenge Colin accepted was implementing changes into a state government system. Historically, this environment had not seen a lot of changes, and now, with the changes in Washington (the government) and the move toward privatization, change was necessary. Plus, his agency director was also new and had announced that the agency would be developing a new strategic plan. Together, Colin had been through many changes recently, and would be involved in more in the near future.
-If Colin focuses on the forces facilitating the change, he would be focusing on the _____ forces.

A) Restraining.
B) Driving.
C) Internal.
D) External.
