Task: Question Answering
Input (English): Passage: At the beginning of the 1850s, Brazil was enjoying internal stability and economic prosperity. The nation's infrastructure was being developed, with progress in the construction of railroads, the electric telegraph and steamship lines uniting Brazil into a cohesive national entity. After five years in office, the successful conservative cabinet was dismissed and in September 1853, Honório Hermeto Carneiro Leão, Marquis of Paraná, head of the Conservative Party, was charged with forming a new cabinet. Emperor Pedro II wanted to advance an ambitious plan, which became known as "the Conciliation", aimed at strengthening parliament's role in settling the country's political disputes.Paraná invited several liberals to join the conservative ranks and went so far as to name some as ministers. The new cabinet, although highly successful, was plagued from the start by strong opposition from ultraconservative members of the Conservative Party who repudiated the new liberal recruits. They believed that the cabinet had become a political machine infested with converted liberals who did not genuinely share the party's ideals and were primarily interested in gaining public offices. Despite this mistrust, Paraná showed resilience in fending off threats and overcoming obstacles and setbacks. However, in September 1856, at the height of his career, he died unexpectedly, although the cabinet survived him until May 1857.The Conservative Party had split down the middle: on one side were the ultraconservatives, and on the other, the moderate conservatives who supported the Conciliation. The ultraconservatives were led by Joaquim Rodrigues Torres, Viscount of Itaboraí, Eusébio de Queirós and Paulino Soares de Sousa, 1st Viscount of Uruguai—all former ministers in the 1848–1853 cabinet. These elder statesmen had taken control of the Conservative Party after Paraná's death. In the years following 1857, none of the cabinets survived long. They quickly collapsed due to the lack of a majority in the Chamber of Deputies. 
Question: What is the full name of the person who died unexpectedly?
Output (English): Honório Hermeto Carneiro Leão, Marquis of Paraná.
