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.

Explanation:
The contemporary <u>agricultural revolution</u> occurred with the increase of technologies to the techniques applied until then.
The objective was to increase production and productivity. The results were obtained through techniques such as crop rotation, seed diversification and equalization of space for livestock.
In England, the law that allowed the purchase of public fields by the upper bourgeoisie was passed. The act forced the migration of small farmers to cities.
These workers would later be the labor force that would supply the factories during the Industrial Revolution.
