Which sentence is most clearly written?

The first sentence, "Proper documentation is crucial for effective law enforcement," is most clearly written because it employs a straightforward and concise structure. The use of "proper documentation" efficiently conveys the idea without unnecessary words, making it direct and easier to understand. This phrasing expresses a strong assertion about the importance of documentation in law enforcement without any qualifiers or overly complex language.

In contrast, the second sentence contains the phrase "Documenting information properly is very crucial," which adds unnecessary complexity by using both "very" and "crucial." The word "very" is often seen as redundant in such contexts, as "crucial" already conveys a strong level of importance. Additionally, the structure is longer and less direct, which can detract from clarity. This makes the first sentence a better choice for clear communication.
