Passage Summary: We have a set of city traffic rules regarding one-way streets, buses, bike lanes, and parking, and we know specifically where Bus 9 drives.

Reasoning: One-way streets always have bike lanes; buses never go where there are bike lanes; parking is forbidden where there are bike lanes; Bus 9 travels on Batchelder Avenue.

Analysis: This is a 'Must be True' logic puzzle that requires combining several conditional statements. Start with the concrete fact: Bus 9 is on Batchelder. Since buses cannot travel on streets with bike lanes, we know Batchelder lacks a bike lane. Because all one-way streets are required to have bike lanes, the absence of a lane proves Batchelder cannot be a one-way street. Therefore, it must be a two-way street.
