Use passive voice to highlight the: action.
Because In a passive sentence, the subject—the person or object being acted upon—comes first, and the actor—who is introduced with the preposition "by"—comes last. The word "was formulated" is used in the passive voice whereas "formulated" is used in the active voice to indicate the verb's passive form.
The passive voice is used to express interest in the person or thing experiencing an action rather than the one performing it. The most significant object or individual, in other words, becomes the sentence's topic. An action is performed on the subject in a phrase written in the passive voice.
Active voice, on the other hand, results in a statement where the subject actually does something. In contrast to active voice, which produces clearer, more succinct statements, passive voice frequently results in ambiguous, indirect, and wordy sentences.
