(the portion of the MC curve below its intersection with the AVC curve is not part of the supply curve because a firm would not operate at price below the shutdown point) This is not true for firms operating in other market structures. For example, while a monopoly ``has'' an MC curve it does not have a supply curve. In a perfectly competitive market, a supply curve shows the quantity a seller's willing and able to supply at each price -- for each price, there is a unique quantity that would be supplied. The one-to-one relationship simply is absent in the case of a monopoly. With a monopoly, there could be an infinite number of prices associated with a given quantity. It all depends on the shape and position of the demand curve and its accompanying marginal revenue curve.
 Question: is marginal cost curve same as supply curve Context: Adjectival noun is a term that was formerly synonymous with noun adjunct but is now usually used to mean ``an adjective used as a noun'' (i.e. the opposite process, as in the Irish meaning ``Irish people'' or the poor meaning ``poor people'').

Although the craniological ethnology that formed its first scholarly context holds no scientific value, the relative chronology of the Stone Age, the Bronze Age and the Iron Age is still in use in a general public context, and the three ages remain the underpinning of prehistoric chronology for Europe, the Mediterranean world and the Near East.
 Question: did the stone age come before the bronze age Context: The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone where it passes through the foramen magnum, and meets and enters the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. Also, the spinal cord has a varying width, ranging from 13 mm (⁄ in) thick in the cervical and lumbar regions to 6.4 mm (⁄ in) thick in the thoracic area.
