Explanation:

• Food scraps are not typically removed and sent to another state in this context.
• Hand - sorting into seven categories is not a common pre - incineration step.
• Health department employees do not usually closely examine garbage for incineration in this way.
• Mixing garbage by an operator to create a constant burn rate is a valid pre - incineration process in waste incineration facilities.

Answer:

The garbage is mixed by an operator before being burned in order to create a constant burn rate.
