A limited government is typically characterized by restrictions on its powers and a stronger emphasis on individual rights and liberties. In contrast, an unlimited government often has broader powers and may suppress individual freedoms for the sake of control.
Out of the options provided, a limited government might be more likely to let citizens speak freely and protest, as it prioritizes individual freedoms and civil rights. Unlimited governments, on the other hand, may suppress such freedoms to maintain control.
The other options (building and maintaining public roads, protecting citizens from attack, and operating public schools) can be tasks performed by both limited and unlimited governments, but they do not necessarily reflect the core principles that differentiate limited governments from unlimited ones.
