Final answer:
The statement about two-tier client/server databases being the most common support system is false, as modern solutions are more diverse. Majority rule can fail with more than two choices, and it's true that native allies and the market revolution played significant roles in their respective historical contexts. Lastly, the U.S. generally has lower voting rates compared to countries like Sweden and South Korea.
Step-by-step explanation:
The question addresses whether a two-tier client/server database is the most common way to support a group working on a project or group of projects.
This statement is false; while two-tier client/server architectures were once commonly used, modern projects often utilize multi-tier architectures or cloud-based solutions to facilitate team collaboration and data management.
Majority rule can indeed fail to produce a single preferred outcome when there are more than two choices.
This scenario is related to what's called the Condorcet paradox in social choice theory, where collective preferences can be non-transitive, leading to no clear winner.
Regarding historical questions, it is true that recruiting native allies was critical in the Spanish conquest of the Aztec, and it is also true that most Indian tribes and nations supported the British during the American Revolutionary War because they feared American expansion.
The market revolution did bring many social and economic changes to the United States, which is also true.
Comparing voting rates, the statement that the United States has higher voting rates than most democratic industrialized countries is false; countries like Sweden and South Korea generally have higher voter turnout rates.
