Passage Summary: To get a big efficiency boost from a new computer, workers have to change how they do things. Since the Ministry is building a system that lets everyone keep working the exact same way, they won't see that boost.

Conclusion: The Ministry of Transportation's new computer system will fail to provide a significant boost to the organization's efficiency.

Reasoning: Significant efficiency gains require employees to adopt new ways of working, but the Ministry's system is specifically designed to accommodate their current work habits.

Analysis: This stimulus relies on a conditional relationship where 'new, more productive ways of working' is a necessary condition for 'significantly increased efficiency.' The Ministry is explicitly bypassing that necessary condition by tailoring the system to existing habits. Therefore, the sufficient condition—the efficiency increase—cannot happen. Look for an answer that completes the logic by stating the efficiency gain won't occur.
