MODEL ANSWER:

Various stages in the process of commercial production of yogurt are sequenced in the given diagram.

In the first step, milk is heated in a vessel to a temperature of 90⁰C for about half an hour. The more time the milk remains in the vessel at this regulated temperature, the thicker the yogurt becomes. In the second step,this milk is allowed to cool to a temperature of 44⁰C. The next major step in the process is the inoculation of live bacteria. Then the temperature is allowed to dwindle to room temperature and the mixture is kept undisturbed for around four hours. In the subsequent step,it is refrigerated to bring down the temperature to a desired level. In the penultimate step, sugar and other sweeteners are added and in the final step,it is packed in air-tight containers and dispatched to various destinations.

Overall,the stages involved in the yogurt-making process appears to be simple in nature.
