Question

In which area did government deregulation benefit both businesses and consumers

Answer 1

(Apologies, this is really late)

Answer:

Not sure what version you may have, but this is what it was for mine:

gas and oil ✔

banking

automobiles

trains

Now if you have the other version where it is airlines instead of trains, then airlines would be the correct answer.

Answer 2

It was the area of flights that benefited a lot of business and consumers. When there is a cheaper rate of flight, the flow of trade will be more convenient, and at the same time, it will also help consumers gain access to products in a lower price.
