4x As urban areas tend to sprawl into the suburbs, this leads to more traffic congestion on the roads. A result of this is longer commutes and more gasoline consumed. Due to taxes on gasoline, this results in increased tax revenues.which can be used to build more highways . A result of this is even further urban sprawl into what was once a rural area This is known as A smart urban growth B a positive feedback loop C a negative feedback loop D a gentrification of an urban neighborhood

## Step 1The problem describes a situation where urban areas expand into suburbs, leading to increased traffic congestion. This, in turn, results in longer commutes and more gasoline consumption. The increased tax revenues from gasoline taxes are used to build more highways, which further encourages urban sprawl into rural areas. This process is repeated, creating a cycle of urban sprawl and increased tax revenues.## Step 2This cycle is an example of a positive feedback loop. A positive feedback loop is a process where the end products of an action cause more of that action to occur. In this case, the urban sprawl leads to increased traffic congestion, which leads to longer commutes and more gasoline consumption, which leads to increased tax revenues, which leads to more highways being built, which leads to more urban sprawl.## Step 3This is different from a negative feedback loop, which is a process where the end products of an action cause less of that action to occur. In a negative feedback loop, the system would self-regulate and stabilize.## Step 4The situation described in the problem is not an example of smart urban growth, which is a planning and policy approach that seeks to create more sustainable and livable cities. It is also not an example of gentrification, which is the process of changing the character of a poor area when rich people acquire property in it.
