Changes in variables other than the price of a good, such as income or the price of another good lead to a change in demand. This corresponds to a shift of the entire demand curve. Critically analyze the law of demand and identify factors that cause demand to shift to the above situation (through diagram)

The elasticity which shows the responsiveness of the demand for a good due to changes in the price of a related good is the:
