Identify the conclusion that effectively recaps the following main idea.
Main idea: Teachers and experts in education agree that classes with between fifteen and twenty students provide the best environments for learning.
a. Teachers should not be responsible for managing too many students. By allocating additional funding to hiring new teachers, districts can keep classes small enough to provide optimal learning environments.
b. With more and more students living at or below the poverty level, school officials must create opportunities to fulfill basic needs. Free breakfast and lunch programs, as well as resources for homeless children will give impoverished students the opportunity to stay in school.
c. Budget cuts are affecting schools in every state in the nation. Many school superintendents feel their hands are tied in regard to class sizes, extracurricular programs, and even bussing because of federal and state cutbacks.
d. As PTAs and individual districts work to integrate technology into more classrooms, publishers are also increasing their software options for the elementary school market. The next generation of scholars will feel more at home surfing a database than in the physical stacks of a library.
