What is a research-based reason he might do this?

A. There is a direct correlation between early-childhood education and decreased drop-out rates and local petty crimes.

B. He knows that teachers receive lower salaries than many local business owners so they should be supported in their chosen profession.

C. He feels it is a citizen's duty to support education for the betterment of the community even if it does not directly affect him or her.

D. He knows that the federal government does not pay for the pre-K programs, and he wants to help the kids.
