* "They" is not specific: "They" could refer to any group of people. Do you mean people in India, or a specific group of Hindi speakers?
* Passive voice is not a language: Passive voice is a grammatical construct found in many languages, including Hindi.
* Frequency of use: While Hindi uses the passive voice, it may not be as common or used in the same situations as in other languages.
To get a better answer, please clarify:
* Who is "they"? Are you referring to people in India, or a specific group of Hindi speakers?
* What are you asking about? Are you curious about the frequency of passive voice use, specific situations where it's used, or something else?
