PLEASE HELP ME #17: Part A - Choose the central idea for the following passage.

While bigger paychecks don't guarantee greater job satisfaction, academic studies indicate that when teacher earnings rise, public school districts and students can benefit in a range of ways.

Research conducted in recent years in various parts of the country and world has helped clarify the role of teacher pay. Many of these studies found that increased pay - whether through salary hikes, one-time bonuses, college debt-forgiveness programs or other new forms of compensation - is associated with: improved teacher retention, gains in student performance, a larger percentage of high-achieving college students taking courses in education, and an increased likelihood of hiring teachers who earned top scores on their educator certification exams.
