Explanation:

The central point in the first paragraph is that the economic benefits of the Olympic Games… Option 1 is incorrect. The economic benefits are shared ‘equally’ among the organizing committees is incorrect. Eliminate option 1.
Option 2 is incorrect. “Revenue from advertisements and ticket sales’ is not referred to in the passage. The paragraph merely states that the Games are an advertisement for the city where they are held.
Option 3 is correct. The writer is skeptical about the economic benefits of the Games to the host city. He says, “Any economic benefit would have to flow from the value of the Games as an advertisement for the city, the new transportation and communications infrastructure that was created for the Games, or the ongoing use of the new facilities.” Retain option 3.
Option 4 is incorrect. The paragraph does not support the inference that the economic benefits that accrue form the games are ‘eroded by expenditure’ on the Games. Eliminate option 4.
Hence, the correct answer is option 3.
