Please answer the questions with microeconomics knowledge ~ ~ ~ Thank you.

From the perspective of substitution, Sichuan oranges and Chongming oranges are mutually substituted, and the decline in the quality of substitutes will lead to an increase in the sales of Chongming oranges.

On the one hand, the quality problem of Sichuan orange may lead to adverse selection because of information asymmetry, which will reduce consumers' recognition of oranges. Bad products will drive good products out of the market, resulting in reduced demand and lower prices.

What is the final specific impact on sales? To comprehensively consider which one has the greater impact, we should also consider the elasticity of demand, the severity of the Sichuan orange incident, consumers' awareness of Chongming orange and so on.

Perhaps the market demand for canned oranges is small, and the market demand for orange juice is large, or orange juice is easier to process. The government's consideration is also analyzed from the perspective of income and cost, and the conditions given in the title are not enough to judge.
