A certain auto repair shop services a particular make of car in the downtown region of a particular city.

All of the following statements, if true, weaken the argument, EXCEPT:

Hillsburgh and Nansensville are two major metropolitan areas only 50 miles apart. Until recently, the only road connecting the two cities was a traffic-clogged, six-lane Interstate Highway.

Mayor of Smalltown: Instituting high taxes on sodas, which are currently untaxed in Smalltown, has been shown in the past year to encourage people to reduce their intake of soda and live healthier lifestyles.
