What is the purpose of taller emissions stacks in industrial settings? a) they are intended to release particulates where there is more wind to carry them away, but this also spreads pollution more widely. b) they allow chemical reactions to take place within the stack, thus creating less harmful particulates to be released from the stack. c) the taller emissions stack are a government requirements of the clean air act amendment, only serving the purpose of compliance to the law d) the particulates typically cannot be carried up in the airstream of a taller stack, so are naturally captured by gravity within the facility producing the pollution e) the taller emission stacks are meant to emit pollutants in a height where they are no longer pollutants any more
