Input: Article: The local councils are responsible for providing the functions set out in the Local Government Act 1989 such as urban planning and waste management. Most other government services are provided or regulated by the Victorian state government, which governs from Parliament House in Spring Street. These include services which are associated with local government in other countries and include public transport, main roads, traffic control, policing, education above preschool level, health and planning of major infrastructure projects. The state government retains the right to override certain local government decisions, including urban planning, and Melburnian issues often feature prominently in state election.

Now answer this question: Which act sets functions for Melbourne such as urban planning and waste management?

Output: Local Government Act 1989

Input: Article: In 1989, Troiden proposed a four-stage model for the development of homosexual sexual identity. The first stage, known as sensitization, usually starts in childhood, and is marked by the child's becoming aware of same-sex attractions. The second stage, identity confusion, tends to occur a few years later. In this stage, the youth is overwhelmed by feelings of inner turmoil regarding their sexual orientation, and begins to engage sexual experiences with same-sex partners. In the third stage of identity assumption, which usually takes place a few years after the adolescent has left home, adolescents begin to come out to their family and close friends, and assumes a self-definition as gay, lesbian, or bisexual. In the final stage, known as commitment, the young adult adopts their sexual identity as a lifestyle. Therefore, this model estimates that the process of coming out begins in childhood, and continues through the early to mid 20s. This model has been contested, and alternate ideas have been explored in recent years.

Now answer this question: In what year did Troiden propose a four-stage model for the development of homosexual sexual identity?

Output: 1989

Input: Article: One early attempt at lengthening the playing time should be mentioned. At least one manufacturer in the early 1920s, World Records, produced records that played at a constant linear velocity, controlled by Noel Pemberton Billing's patented add-on governor device. As these were played from the outside to the inside, the rotational speed of the records increased as reproduction progressed. This action is similar (although in reverse) to that on the modern compact disc and the CLV version of its predecessor, the Philips Laser Disc.

Now answer this question: What caused the constant linear velocity?

Output:
Noel Pemberton Billing's patented add-on governor device
