Explanation:

- The passage describes the skyscraper, Central Park Tower, which has become the tallest residential building globally.

- The sentence with the blank talks about apartments and mentions monetary amounts in the following sentences.

- Option 1: prices - This option fits well as the paragraph likely discusses the cost-related aspect of apartments.

- Option 2: bills - Doesn't fit as it doesn't align with a description about an apartment's financial aspect like cost.

- Option 3: amounts - Doesn't precisely capture the general term like prices when discussing real estate in such a context.

- Option 4: values - Could work, but not as directly relevant as prices when talking about transactions or affordability.

Correct Answer: Option 1 - prices
