Question

based on this excerpt, what fact supports kamens belief that the segway may change the way people move around crowded cities?
kamen also invented the ibot, a wheelchair that can climb stairs.
the segway contains five gyroscopes that keep it balanced.
segways can reduce the amount of car traffic and auto emissions.
kamen invented the segway to be used in many parts of the world.

Explanation:

The question is about finding a fact that supports the belief that the Segway can change how people move in crowded cities. Reducing car traffic and emissions (as in the third option) directly relates to urban movement patterns. The first option is about another invention (Ibot), the second is about Segway's internal mechanism (gyroscopes - not directly about city movement change), and the fourth is about global use (not specifically city - movement - change related).

Answer:

Segways can reduce the amount of car traffic and auto emissions.
