question 1 (1 point)
which of the following sustainable city elements would be the most difficult to incorporate into a bustling city in an industrialized country?

a high - speed rail systems
b greenways
c rooftop gardens
d hydroponic gardens

Explanation:

To determine the most difficult sustainable city element to incorporate, we analyze each option:

• Greenways (b) are linear parks or trails, which can be added to existing urban spaces with planning.
• Rooftop gardens (c) utilize existing building rooftops, requiring structural checks but feasible.
• Hydroponic gardens (d) are indoor/urban farming systems, scalable in limited spaces.
• High - speed rail systems (a) require extensive land acquisition, complex infrastructure (tracks, stations), and coordination with existing urban layouts, transportation networks, and land use in a bustling industrialized city. Industrialized cities have dense development, established transit, and land scarcity, making high - speed rail integration extremely challenging due to costs, disruption, and spatial constraints.

Answer:

a. high - speed rail systems
