A good answer might include the following observations:

Loravia spends a higher amount on education and also has a lower student/teacher ratio compared to the majority of its neighbors and its economic peers.
Despite both of the above, Loravia has one of the lowest international assessment scores.
Broadly, there seems to be no direct relationship between student to teacher ratio and education outcome as measured by the international assessment.
Developed countries clearly spend more per student on education and have better outcomes as measured by the international assessment. However, among Loravia’s peers and neighbors there is no clear relationship between spending and education outcomes.
While student/teacher ratios and per student funding are levers that could be considered important in improving education quality, the data here indicates that these may not in themselves provide the necessary improvement. Issues such as teacher quality and curriculum content should be investigated.
