choices.text: new york:dow jones index cpi:consumer price index environmental protection:happiness index food expenditure:engel's coefficient
explanation: "gini coefficient" refers to a common indicator used internationally to measure the income gap of residents in a country or region, and "gini coefficient" is used to reflect "income distribution". the "dow jones index" is the oldest stock index in the world. its full name is the stock price average index. "dow jones index" has no obvious logical relationship with "new york". the "consumer price index" is a macroeconomic indicator that reflects the price level changes of consumer goods and services generally purchased by households. "consumer price index" is abbreviated as "cpi". there is no obvious logical relationship between "environmental protection" and "happiness index" "engel's coefficient" is the proportion of total food expenditure to total personal consumption expenditure, and "engel's coefficient" is used to reflect "food expenditure".
