Hello. You did not enter the text to which this question refers, which makes it impossible to answer it specifically and efficiently. However, I will try to help you in the best possible way.
To answer this question, it is first necessary to read the entire text to which it is related. Then, it is important to understand that public works spend public money that should be collected from the payment of taxes by the population, so how does this stimulate the economy and resource management? in relation to resource management, public works allow the government to spend resources on what is most needed in society and which will promote the general good. This general good should promote an increase in the economic capacity of the population, allowing the country's economy to be stimulated. An example of this is the creation of bridges that will allow people to get to work faster, being able to be more productive and earn better wages.
In that case, you should look in your text for evidence that shows that public works were necessary in one region and that it would promote an economic incentive in the same region.
