Answer:
Fans and Manufacturing!
Explanation:
Lets cross all the options that do not apply.
A) It cannot be schools and teachers because in the article Pinball, it does not say anything about schools or teachers. So it cannot be that.
B) It is fans and manufacturing. This is it because fans help make the pinball machines more popular which makes the manufactures produce more of them. This is also the most logical one
C: It can be parents and children, but fans and manufacturing applies to the question better. Parents and children can help, but who kows if they will help make the future of pinball machines great right!? Therefore it cannot be C.
Don't even get me started with D
Hope it helps :)
