Which sentence is most clearly written?

The first sentence, which states that Dr. Gerard worked at the precinct station as a staff psychologist, is most clearly written due to its simplicity and straightforwardness. The use of the word "worked" conveys the meaning effectively without unnecessary complexity. This choice presents the information in a concise and direct manner, making it easy for readers to grasp the essential details about Dr. Gerard's role.

The second sentence employs "was employed," which adds an extra layer of formality and can make the sentence feel less direct. While it is still clear, it introduces a slight ambiguity that detracts from the directness found in the first sentence. In written communication, clarity is often favored, and simpler phrases typically improve readability.

When comparing both sentences, the first one stands out as the more effective choice for clear communication.
