Final answer:
The question likely references historical construction events in Florida, though 'Tobias' isn't mentioned in the provided passages. Contextually, it may relate to historical figures like Oglethorpe or Wright who were known for significant building efforts.
Step-by-step explanation:
The student's question about what Tobias was able to start building in the second year of living in Florida is a reference to historical events related to the colonization and defense of early American territories. From the provided references, it seems most likely that this question is intended to pertain to the broader historical context of settlers and colonial figures like James Oglethorpe in Georgia and builders like Frank Lloyd Wright. However, based on the passages provided, there is no direct mention of someone named Tobias.
The closest related historical event would be the construction started by James Oglethorpe and the Georgia colonists. Over a decade, they built a chain of forts on Georgia's coast to defend against the Spanish, with Fort Frederica as the crucial fortified outpost. Frank Lloyd Wright's construction of Taliesin West also ties into the theme of building significant structures.
