Question

Which of these choices was not a duty of the assembly?

Answer 1

Answer: Acting as a Supreme Court

Explanation:

You did not mention the relevant assembly however the above should be correct.

Assemblies usually belong to the Legislative arm of Government which means that they pass laws and in certain countries run the army and even choose the generals or admirals in the nation's forces.

Supreme Courts however, belong to the Judicial branch of government. As these two are in separate branches, they have separate powers and are not to impede on their respective powers. Acting as a Supreme Court is therefore most likely correct here.
