Final answer:
To adopt a parliamentary inquiry or pass ordinary laws, a simple majority is usually required, but specific instances like early elections or impeachment processes may necessitate a supermajority.
Step-by-step explanation:
The question about what vote is required to adopt a parliamentary inquiry pertains to parliamentary procedure, which falls under the scope of Social Studies at the high school level. In the context of countries with a parliamentary system, various types of votes may be needed for different parliamentary actions. For the passage of ordinary laws, a simple majority, which is 50 percent plus one vote, is typically sufficient.
However, there are instances where a supermajority is required, such as calling early elections in the UK, which necessitates two-thirds of Parliament's agreement. Similarly, in the United States, an impeachment process requires a simple majority in the House of Representatives to advance to trial, but a two-thirds majority in the Senate is needed for conviction. In contrast, individual legislators can submit parliamentary questions without needing cooperation from other members, providing a valuable tool for minority parties to initiate inquiries.
