A study examining ninety large cities found that in those with more kilometers of bicycle paths and roadway bicycle lanes per capita, higher percentages of the population commute to work by bicycle. For this reason the study concluded that adding bicycle paths and lanes is an effective way to encourage commuters to bicycle rather than drive.

A study examining ninety large cities found that in those with more kilometers of bicycle paths and roadway bicycle lanes per capita, higher percentages of the population commute to work by bicycle. For this reason the study concluded that adding bicycle paths and lanes is an effective way to encourage commuters to bicycle rather than drive.

Which of the following, if true, would most weaken the reasoning in the study’
A . The higher the percentage of a city’s population commutes by bicycle, the stronger political pressure there is for the city to add bicycle paths and lanes.
B . A large percentage of urban bicycle commuters commute via roadway bicycle lanes but use bicycle paths mainly for recreation.
C . Even in communities with extensive bicycle paths and roadway bicycle lanes, many commuters drive rather than bicycle to work because of the perceived danger of bicycling in traffic.
D . On average, cities with climates more pleasant for bicycling have fewer kilometers of bicycle lanes and paths per capita than those with harsher climates.
