Final answer:
The question on how most people in Chile feel about the nation's constitution cannot be definitively answered with the information provided, but a referendum's failure can be attributed to factors such as satisfaction with the current constitution or a lack of voter turnout.
Step-by-step explanation:
Based on details in the referenced article, it is not possible to determine how most people in Chile feel about Chile’s constitution as the information provided does not specifically address public opinion in Chile. However, in general, when a referendum to replace a constitution fails, it can be due to a variety of factors, such as contentment with the current constitution, lack of awareness or understanding of the proposed changes, political campaigning by those opposing the new constitution, or broader societal concerns.
Regarding why the referendum to replace the constitution failed, details from the article do not directly refer to a particular referendum in Chile.
However, based on general information, a referendum may fail if a significant portion of the electorate believes that the changes proposed are not in their best interest, if there is a division between different factions or groups, or if there is a significant decrease in the number of voters, like the drop from 87 percent to 46 percent participation mentioned.
Economic and political conditions, including the surge in economic development in Chile and the country's move to an upper-middle-income nation with increased freedoms, might also influence voters to maintain the status quo.
