Question

aa.4 use context to identify the meaning of a word select the text from the paragraph that best helps you understand that cupola means dome. there may be more than one correct choice. construction on florences grand cathedral began in 1296. over a hundred years later, however, the structure remained unfinished, with an enormous hole in the roof. the designers had intended to top the cathedral with the worlds largest dome, but this plan was stymied by architectural limitations. the main factor stalling progress was the fact that no one knew how to create such a massive cupola without large, cumbersome support systems.

Explanation:

To determine the text that helps understand "cupola" means "dome", we look for context clues. The sentence "The designers had intended to top the cathedral with the world's largest dome, but this plan was stymied by architectural limitations. The main factor stalling progress was the fact that no one knew how to create such a massive cupola without large, cumbersome support systems." connects "dome" and "cupola" as the designers' plan for the dome is related to creating the cupola, showing they are similar in meaning (the cathedral's top structure). Also, the earlier mention of an "enormous hole in the roof" and the plan to top it with a dome, then the issue with the cupola, links them. The key text is "The designers had intended to top the cathedral with the world's largest dome, but this plan was stymied by architectural limitations. The main factor stalling progress was the fact that no one knew how to create such a massive cupola without large, cumbersome support systems." (or the relevant part where dome and cupola are contextually linked, like the part about intending a dome and then the cupola creation problem).

Answer:

The text that best helps is: "The designers had intended to top the cathedral with the world's largest dome, but this plan was stymied by architectural limitations. The main factor stalling progress was the fact that no one knew how to create such a massive cupola without large, cumbersome support systems." (or the relevant sentence/phrase that links dome and cupola in the context of the cathedral's roof structure, such as the part showing the plan for the dome and the problem with the cupola creation)
