Which sentence is most clearly written?

The first sentence is most clearly written because it maintains a single, continuous thought that conveys the officer's desire for a new partner with a specific qualification—experience. Here, the use of a comma effectively connects the two related ideas without breaking the flow of the sentence, ensuring clarity and coherence for the reader.

In contrast, the second sentence separates the ideas into two distinct sentences, which can lead to a choppy reading experience and can blur the connection between the officer's hope and the specific type of partner desired. This division can cause confusion, as it may suggest a shift in thought rather than a continuation of the original premise. The clarity in the first option makes it easier for the reader to understand the officer's intent.
