Detailed Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Q: Passage: Following the hasty departure of Pedro I, Brazil was left with a five-year-old boy as head of state. With no precedent to follow, the Empire was faced with the prospect of a period of more than twelve years without a strong executive, as, under the constitution, Pedro II would not attain his majority and begin exercising authority as Emperor until 2 December 1843. A regency was elected to rule the country in the interim. Because the Regency held few of the powers exercised by an emperor and was completely subordinated to the General Assembly, it could not fill the vacuum at the apex of Brazil's government.The hamstrung Regency proved unable to resolve disputes and rivalries between national and local political factions. Believing that granting provincial and local governments greater autonomy would quell the growing dissent, the General Assembly passed a constitutional amendment in 1834, called the Ato Adicional (Additional Act). Instead of ending the chaos, these new powers only fed local ambitions and rivalries. Violence erupted throughout the country. Local parties competed with renewed ferocity to dominate provincial and municipal governments, as whichever party dominated the provinces would also gain control over the electoral and political system. Those parties which lost elections rebelled and tried to assume power by force, resulting in several rebellions.The politicians who had risen to power during the 1830s had by then become familiar with the difficulties and pitfalls of power. According to historian Roderick J. Barman, by 1840 "they had lost all faith in their ability to rule the country on their own. They accepted Pedro II as an authority figure whose presence was indispensable for the country's survival." Some of these politicians (who would form the Conservative Party in the 1840s) believed that a neutral figure was required—one who could stand above political factions and petty interests to address discontent and moderate disputes. They envisioned an emperor who was more dependent on the legislature than the constitutional monarch envisioned by Pedro I, yet with greater powers than had been advocated at the beginning of the Regency by their rivals (who later formed the Liberal Party). The liberals, however, contrived to pass an initiative to lower Pedro II's age of majority from eighteen to fourteen. The Emperor was declared fit to rule in July 1840.
