Answer: D) Segmental level, projection level, precommand level
Explanation: The hierarchical organisation of the motor control system is only one aspect, besides it there is a parallel one. The motor control system is responsible for regulating movement and as such is crucial for the body's motility, which includes directional movement and reflexes. Of course, motor control only exists in organisms that have a nervous system.
As for the hierarchy of the motor control system, the lowest in the hierarchy is the segmental level. It consists of reflexes and parts of the nervous system in charge of automatic movements.
Second in the hierarchy from the lowest to the highest is the projection level and helps in the functioning of the segmental level, i.e, for the regulation of reflexes and for monitoring the multi neuronal system.
The highest level is the precommand level, which is responsible for controlling the output impulses that control the finest, most precise movements of the body, responsible for starting and stopping movements, regulating the muscles, and preventing unwanted movements.
The dependent variable in this study is Experimenter -bias.
<h3>What is meant by Experimenter bias?</h3>
Experimenter Bias is a type of cognitive bias that occurs when experimenters allow their expectations to affect their interpretation of observations.
Experimenter bias is the unconscious tendency for researchers to treat members of the experimental and control groups differently to increase the chance of confirming their hypothesis.
<h3>What is a Dependent Variable in an Experiment?</h3>
The Dependent variable is the variable that is being measured or tested in an experiment.
A dependent variable is the variable that changes as a result of the independent variable manipulation. It's the outcome you're interested in measuring, and it “depends” on your independent variable. In statistics, dependent variables are also called: Response variables (they respond to a change in another variable)

You have not described the alternatives, but as an economist I can help you!
The Federal Reserve is the body that decides the direction of US monetary policy. The economic decisions of the agency can be expansive, when they stimulate the economy, or restrictive, when they slow economic growth.
The two main tools the Federal Reserve has in conducting monetary policy are the<u> interest rate</u> and the <u>open market</u>.
We say that monetary policy is restrictive when the Federal Reserve increases the interest rate or sells government bonds (by decreasing the amount of money in circulation). These measures are taken to slow down the economy and prevent the inflationary process.
The opposite occurs when the Federal Reserve buys securities and / or lowers the interest rate, measures that occur to stimulate the economy when economic activity is stagnant.
