Hello, i am just trying to solve this question and am stuck on how it do it. This is all the information provided.

Prior to 1991, Telecom Australia (currently known as Telstra) was the only telecommunications services provider in Australia. Following the recommendation of Davidson inquiry, legislation was passed in 1991 allowing duopoly competition. Optus Communications became Australia's second general telecommunications carrier. It was guaranteed access to Telstra's existing infrastructure on reasonable terms. After 1997, any telecom company willing to purchase a carrier license was allowed to enter the Australian telecommunications market.

(a) explain the rationale behind the government of Australia deregulating the telecommunications market?

(b) Why was Optus guaranteed access to Telstra's infrastructure? Explain

(c) To what extent has the government been successful in achieving its objective? Provide a brief explanation using some statistical evidence.
