Copenhagen sees heavy foot traffic, but merely copying one feature linked to its walkability—say, its dense network of narrow lanes—may not be enough to get people walking more in other cities. As the urbanist Deval Rao contends, our grasp of how individuals decide whether to walk remains too shaky: some studies stress demographics, others the reach of public transit, and so on, yet walking choices emerge from tangled settings in which many conditions and needs shape what a person does.

Based on the text, Rao would most likely agree with which statement about studies of decisionmaking about walking?

• A.

  They would improve if researchers pinned down what cities with heavy foot traffic have in common.

• B.

  They have exaggerated the extent to which people's walking decisions differ from one another.

• C.

  They tend to mislead because they overlook the single most important influence on walking.

• D.

  They are unlikely to turn up solid proof that any one factor reliably predicts whether people walk.
