Prompt: EVIDENTIAL SUPPORT & CRITIQUE

The following appeared in a letter to the editor of Parson City's local newspaper.

"In our region of Trillura, the majority of money spent on the schools that most students attend—the city-run public schools—comes from taxes that each city government collects. The region's cities differ, however, in the budgetary priority they give to public education. For example, both as a proportion of its overall tax revenues and in absolute terms, Parson City has recently spent almost twice as much per year as Blue City has for its public schools—even though both cities have about the same number of residents. Clearly, Parson City residents place a higher value on providing a good education in public schools than Blue City residents do."

Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.

In the Trillura region, public schools are funded in large part by city taxes.  Each city budgets differently on their schools.  For instance, Parson City spent more in terms of percent of its tax revenue and in absolute terms than Blue City on public schools.  Both cities have the same number of residents. 
Based on this information, it has been argued that Parson City values public education more than Blue City.  However, more data is needed before assessing this conclusion.  We need to know more about the student population of PC and BC, more about the exchange of students between cities, the kinds of schools offered in each city, and the overall tax revenue of each city. 

First, if Parson City has a greater number of students attending their public schools than Blue City, then it would be reasonable for Parson City to spend more on education than Blue City.  In that case, the money spent per student may be the same in both cities.  This would also be the case if the families of Blue City send more of their students to a neighboring city.  In either case, we need to know more about the student population of Blue City and Parson City before assessing the conclusion that Parson City values public education more than Blue City. 

Next, Blue City public schools may be different in kind than Parson City public schools.  For instance, in some cities across the United States, public education is more focused on specific vocational training.  Since these public schools have narrow curriculum, they require fewer teachers; and therefore, their overall budgets in comparison to general education based public schools are reduced.  In the case that Parson City public schools are different in kind than Blue City public schools, the conclusion that Parson City values public education more than Blue City would be rejected as unsound. 

Lastly, Parson City may collect more in overall tax revenue than Blue City. Suppose that Parson City has collected ten dollars and Blue City has collected five dollars in tax revenue.  Next, suppose that Parson City allocated 10% of its tax revenue to public education, leaving it with nine dollars to spend elsewhere.  Lastly, assume that for the entire Trillura region, the annual cost of sanitation is four dollars.  In this case, if Blue City spent the same proportion of their tax revenue on public education as Parson City, then they would have nothing left to support other basic needs such as health care, and infrastructure.  Prior to assessing the conclusion that Parson City values public education more than Blue City, we need to know more about the tax revenue of each respective city. 

Without the requested further information concerning the student population of PC and BC, the exchange of students between cities, the kinds of schools offered in each city, and the overall tax revenue of each city, adjudication must be withheld concerning the conclusion that Parson City values public education more than Blue City.
