Task: Question Generation
Input (English): Passage: Gil González Dávila set out from the Caribbean island of Hispaniola early in 1524, with the intention of exploring the Caribbean coast of Nicaragua. His course took him to the north coast of Honduras. After founding Puerto de Caballos, Gil Gónzalez sailed west along the coast to the Amatique Bay, and founded a Spanish settlement somewhere near the Dulce River, within modern-day Guatemala, which he named San Gil de Buena Vista. He launched a campaign of conquest in the mountainous region dividing Honduras from Guatemala. González left some of his men under the command of Francisco Riquelme at San Gil de Buena Vista, and sailed back east along the coast to Honduras. The colonists at San Gil did not prosper, and soon set out in search of a more hospitable location. They resettled in the important indigenous town of Nito, near the mouth of the Dulce River. Although they were in a desperate state, and near-starving, they were still there when Cortés passed through en route to Honduras, and were absorbed into his expedition.The Dominicans established themselves in Xocolo on the shore of Lake Izabal in the mid-16th century. Xocolo became infamous among the Dominican missionaries for the practice of witchcraft by its inhabitants. By 1574 it was the most important staging post for European expeditions into the interior, and it remained important in that role until as late as 1630, although it was abandoned in 1631.In 1598 Alfonso Criado de Castilla became governor of the Captaincy General of Guatemala. Owing to the poor state of Puerto de Caballos on the Honduran coast and its exposure to repeated pirate raids he sent a pilot to scout Lake Izabal. As a result of the survey, and after royal permission was granted, Criado de Castilla ordered the construction of a new port, named Santo Tomás de Castilla, at a favourable spot on the Amatique Bay not far from the lake. Work then began on building a highway from the port to the new capital of the colony, modern Antigua Guatemala, following the Motagua Valley into the highlands. Indigenous guides scouting the route from the highlands would not proceed further downriver than three leagues below Quiriguá, because the area was inhabited by the hostile Toquegua.
