Question

question 9
educational researchers have long debated the impact of class size on student achievement. a study conducted by the national education policy center examined data from over 1,000 schools across various states, focusing on classes with fewer than 20 students versus those with more than 30. the researchers found that smaller classes allowed for more individualized attention, leading to higher test scores and better overall academic performance. additionally, teachers in smaller classes reported being able to cover more material in - depth and engage students in more interactive and participatory learning activities. these findings suggest that ______

question 10
theobromine, a bitter alkaloid of the cacao plant, is also found in a number of other plants such as tea leaves and the kola nut. its a primary ingredient in chocolate and contributes to the foods characteristic taste. interestingly, scientists have found that theobromine is more effective than fluoride in remineralizing and hardening tooth enamel when added to toothpaste. despite these findings, most toothpaste manufacturers have yet to replace fluoride with theobromine. this leads to the speculation that ______

Explanation:

Question 9

The study shows smaller classes (fewer than 20 students) lead to individualized attention, higher test scores, better academic performance, and more in - depth teaching/engaging activities. So the blank should be a conclusion about the positive impact of smaller class sizes on student achievement and teaching. For example, "smaller class sizes have a positive impact on student achievement and the quality of teaching, and schools should consider reducing class sizes to improve educational outcomes" (or other reasonable conclusions based on the study's findings like "smaller class sizes are beneficial for both student learning and teacher - led instruction").

Theobromine is more effective than fluoride in remineralizing and hardening tooth enamel, but manufacturers still use fluoride. So the blank should be a speculation about why this is the case, such as "there may be other factors (like cost, production difficulty, or lack of awareness) that prevent manufacturers from using theobromine in toothpaste despite its effectiveness" (or other reasonable speculations about the barriers to replacing fluoride with theobromine).

Answer:

Smaller class sizes have a positive impact on student achievement and the quality of teaching, and schools should consider reducing class sizes to improve educational outcomes (or other reasonable conclusions based on the study's findings)
