Final answer:
People support parliamentary systems because they offer greater political stability and continuity. The combination of the executive and legislative branches in these systems ensures smoother government functioning, without the risk of a divided government. The prime minister's power to dissolve the lower house also allows for better decision-making and responsiveness to the will of the people.
Step-by-step explanation:
One of the best explanations for why people support parliamentary systems is that they offer greater political stability and continuity. In parliamentary systems, the executive and legislative branches are combined, and the prime minister is chosen from within the legislature. This close relationship between the executive and legislative branches ensures that the government can function more smoothly without the risk of a divided government. Additionally, the prime minister's power to dissolve the lower house before the completion of its term allows for better decision-making and responsiveness to the will of the people.
