I want to know the answer to the following question:
In what year was the first Aboriginal Senator elected?
All the background I'm provided with is that "Historically, Liberal Governments have been responsible for the carriage of a number of notable "socially liberal" reforms, including the opening of Australia to multiethnic immigration under Menzies and Harold Holt; Holt's 1967 Referendum on Aboriginal Rights; Sir John Gorton's support for cinema and the arts; selection of the first Aboriginal Senator, Neville Bonner, in 1971; and Malcolm Fraser's Aboriginal Land Rights Act 1976.". Is that enough to answer the question?
Answer: yes
