A city's bike-share ridership at the five stations nearest downtown doubled after the network added 40 new stations citywide, and transit officials announced that "the expansion doubled ridership." Ridership figures for the network's other 35 stations were not included in the announcement. Which choice most accurately identifies the weakness in the officials' reasoning?
- It generalizes from ridership at a handful of downtown stations to the entire network, without reporting whether the other stations showed the same pattern.
- It proves that adding new stations to a bike-share network always reduces ridership at every single station built anywhere outside the city's downtown core, no matter how far from downtown that station happens to be located.
- It assumes every rider at the five downtown stations was a first-time bike-share user.
- It relies on ridership counts the passage says a technical glitch had inflated.
- It confuses "stations" with "riders" as though the two words meant the same thing.
