Question: Passage: Though researchers generally believe that sexual orientation is not determined by any one factor but by a combination of genetic, hormonal, and environmental influences, with biological factors involving a complex interplay of genetic factors and the early uterine environment, they favor biological models for the cause. They believe that sexual orientation is not a choice, and some of them believe that it is established at conception. That is, individuals do not choose to be homosexual, heterosexual, bisexual, or asexual. While current scientific investigation usually seeks to find biological explanations for the adoption of a particular sexual orientation, there are yet no replicated scientific studies supporting any specific biological etiology for sexual orientation. However, scientific studies have found a number of statistical biological differences between gay people and heterosexuals, which may result from the same underlying cause as sexual orientation itself. Question: What do researchers generally believe causes sexual orientation?

Answer: a combination of genetic, hormonal, and environmental influences

Question: Passage: Domestically, Menzies presided over a fairly regulated economy in which utilities were publicly owned, and commercial activity was highly regulated through centralised wage-fixing and high tariff protection. Liberal leaders from Menzies to Malcolm Fraser generally maintained Australia's high tariff levels. At that time the Liberals' coalition partner, the Country Party, the older of the two in the coalition (now known as the "National Party"), had considerable influence over the government's economic policies. It was not until the late 1970s and through their period out of power federally in the 1980s that the party came to be influenced by what was known as the "New Right" – a conservative liberal group who advocated market deregulation, privatisation of public utilities, reductions in the size of government programs and tax cuts. Question: Were utilities publically or privately owned in Menzie's economy?

Answer:
publicly
