Since the factory installed its new ventilation system, reported respiratory complaints among workers have fallen by half. No other change to working conditions coincided with this decline, and the drop appeared immediately after installation rather than accumulating gradually. The most plausible account, then, is that the ventilation system, and not some unrelated background trend, is responsible for the improvement in workers' respiratory health.
Which one of the following most accurately expresses the main conclusion of the argument?
- Since the new ventilation system was in fact installed, reported respiratory complaints among workers have fallen by half.
- The new ventilation system has eliminated respiratory complaints among the factory's workers.
- The new ventilation system, and not some unrelated background trend, is responsible for the improvement in workers' respiratory health.
- The decline in complaints appeared immediately after installation rather than accumulating gradually.
- The factory's workers experienced fewer respiratory complaints because production volume fell immediately after installation and remained lower throughout the reporting period.
