What is the best paraphrase of the section titled "How is cereal made?"

W. When cereal is made, grain is mixed with flavoring agents, vitamins, minerals, sweeteners, salt, and water in a pressure cooker. After this, the cooked grain is cooled and shaped by large metal rollers. Large ovens then cook the grain to the desired color, flavor, and dryness. Grain ground into flour is cooked in a cooking extruder. Cereals can be made in a wide variety of shapes, such as circles and letters of the alphabet, with a cooking extruder.

X. The most important ingredient to any breakfast cereal is grain. The grain is mixed with flavoring agents, vitamins, minerals, sweeteners, salt, and water in a large rotating pressure cooker. The cooked grain is then cooled and shaped by large metal rollers. Grain ground into flour is cooked in a cooking extruder, which has a long screw and a heating mechanism. After shaping, the cereal may be coated with vitamins, minerals, sweeteners, and flavors.

Y. Cereal is made by first inspecting and cleaning a type of grain. The grain is then mixed with other important ingredients in a pressure cooker, dried in an oven, cooled, and then shaped by metal rollers. Large ovens then cook the grain again. If the grain is ground into flour, then a cooking extruder is used, which allows cereals to be made into special shapes. The cereal may be covered with more vitamins, minerals, and flavors after shaping.

Z. The manufacturing process of cereal begins with inspecting and cleaning a type of grain. The grain then needs to be crushed to remove the bran, mixed with flavoring agents, and dried. Large metal rollers shape the cooked grain. The shape and pressure of the rollers depends on the cereal being made. Large ovens cook the grain. The grain can also be cooked by a cooking extruder, a neat contraption that shapes the grain into a ribbon.
