Discussion

Explanation:

The first three options can be found explicitly stated in the last two paragprahs: “ Another …problem is that urban land is generally scarce and growing scarcer. The new facilities often stand for decades or longer. Even if they have future use, are they the best use of precious urban real estate? Further, cities must consider the human cost. Residential areas often are razed and citizens relocated (without adequate preparation or compensation). Life is made more hectic and congested. There are, after all, other productive uses that can be made of vanishing fiscal resources.” Option 1 about the diversion of scarce spaces, option 2 about the demolition of residential structures, and option 3 about the better use of funds for other purposes, are stated in the passage and they get eliminated.
Option 4 which is about the influx of visitors is not mentioned as a burden on the host city.
Hence, the correct answer is option 4.
