Step-by-step explanation:
D. Increasing funding to schools became a solution toward improving the education system.
While creating standardized tests and starting the use of homework are tools that can be used to measure student learning and improve academic performance, they are not solutions to improving the education system as a whole. Similarly, increasing the hours per day students work may not necessarily lead to better outcomes if the quality of education being delivered is inadequate.
On the other hand, increasing funding to schools can help provide the resources needed to improve the quality of education being delivered, including hiring more teachers, improving facilities, and investing in educational technology. This can lead to better learning outcomes for students and a more effective education system overall.
