Explanation:

First Question: How does multi - modal transportation contribute to sustainability?

To determine how multi - modal transportation contributes to sustainability, we analyze each option:

• Option a: Expanding fuel - powered routes would likely increase fuel consumption and emissions, which is not sustainable. So this option is incorrect.
• Option b: Multi - modal transportation involves combining different transit modes (like buses, trains, bicycles, etc.). By doing so, we can reduce the reliance on single - occupancy, high - emission vehicles (like cars). This helps in cutting down emissions, which is a key aspect of sustainability. So this option is correct.
• Option c: Raising single - car trip counts would increase the number of cars on the road, leading to more emissions and congestion, which is not sustainable. So this option is incorrect.
• Option d: Increasing highway construction is more about infrastructure expansion for cars and does not directly contribute to sustainability in terms of transportation efficiency or emission reduction. So this option is incorrect.

To find the feature that most improves walkability in a city, we analyze each option:

• Option a: Safe pathways and sidewalks provide a secure and comfortable environment for pedestrians. When people feel safe walking, they are more likely to choose walking as a mode of transportation, thus improving walkability.
• Option b: Limited public transit routes do not directly relate to walkability. In fact, good public transit can complement walkability, but limited routes would not improve how easy it is to walk in the city.
• Option c: Adding more vehicle lanes is focused on improving car traffic flow, not walkability. It may even make walking less attractive by increasing the space for cars and potentially reducing the space for pedestrians.
• Option d: Expanded private car access encourages the use of cars, which can make walking less convenient (more traffic, less space for pedestrians) and does not improve walkability.

Answer:

b. Combining transit modes to cut emissions
