Based on the questionnaire, the investigation reveals the following conclusions:
1. The duration of the thermal power plant's presence in the locality is unknown as the questionnaire does not ask for that information.
2. People in the locality have indeed suffered respiratory problems due to the polluted air around the power plant, as indicated by the second question on the questionnaire.
3. The questionnaire does not provide any specific suggestions or actions to prevent the power plant from polluting the air. Therefore, it cannot be concluded what actions should be taken based on the questionnaire alone.
4. The questionnaire does not provide information about the contribution of the sheet metal factory to the air pollution in the locality. Therefore, it is not possible to determine the extent of its impact without further investigation.
