3. Edit the following passage by rewriting unnecessary uses of the passive voice into the active voice.
Having cash registers full of change was found to increase the likelihood of a late-night robbery. In one example, a store clerk was held up at gunpoint. It was decided by management that requiring full payment for gasoline in advance of a purchase would minimize the risk of further holdups. This course of action had been voted on by the board of directors prior to implementation. The decision was posted at each location. Following implementation of the policy, it was discovered that holdups were not minimized unless large signs indicating the clerks’ lack of available cash were placed in plain view. Once this was done, fewer holdups were experienced, and the turnover of late-night personnel was decreased.
