Politician: Our government’s Ministry of the Environment issues scientific assessments of the ecological impacts of industrial activities.
Conclusion
The Ministry of Health should not issue scientific assessments that relate to health issues.

The answer should say something that we know is applicable to the MoE / MoH and then give us the power to conclude something that pushes in the direction of "the MoH shouldn't issues assessments for health issues".
