Australian Citizenship Practice Exam

The main function of the Senate in Australia is to review and amend legislation and represent the interests of the states. This upper house of Parliament plays a crucial role in the legislative process, as it provides checks and balances to the House of Representatives. Senators are elected to represent their state or territory, ensuring that various regional interests are considered in national decision-making.

When legislation is proposed, the Senate scrutinizes it, assesses its implications, and can suggest amendments. This function helps to ensure that laws are carefully evaluated from multiple perspectives, ultimately contributing to more thoughtful and effective governance. The representation of states is particularly important in a federation like Australia, where different regions may have distinct needs and priorities.

The other options do not accurately represent the Senate's primary role; for instance, while the Senate can suggest amendments and challenge legislation, it does not have the authority to pass laws without amendments or oversee the judiciary. Additionally, the election of the Prime Minister is primarily the responsibility of the House of Representatives, not the Senate.
