Question

read the passage.

with an area of just over two square kilometers, the nation of monaco must find innovative ways to expand its habitable space while keeping sustainable practices and conservation efforts in mind. the fifteen - acre mareterra district, a construction project with housing, a promenade, cycle paths, a park, and a marina, is a case in point.

built on artificial land in the mediterranean sea, mareterras structural integrity relies on a foundation of sand - filled concrete chambers. these caissons support the districts buildings and other features for residents to enjoy. first, however, developers enacted a variety of environmental protections, which included building artificial seagrass beds for marine life. these measures ensured a design more amenable to ocean ecosystems than previous artificial landmass projects in monaco. while these past plans garnered criticism for negative impacts on the environment, mareterra evinces more sustainable living models. for instance, solar panels serve as a renewable source for heating and cooling. the district is pedestrian in nature, as denoted by its swath of walking paths. it also includes green spaces for sightseeing and gathering that balance residences and shops.

which statement best summarizes the central ideas of the passage?

• monacos mareterra district extends the countrys size by stretching into the mediterranean sea. free of indoor structures, this area serves as a green space of parks and pathways for the nations residents.
• monacos mareterra district stands upon sturdy foundational structures in the mediterranean sea. these caissons engendered criticism of the project because of their materials and location.
• monacos mareterra district provides living space via an artificial land mass. in contrast to previous projects, mareterras design implements conservation measures and promotes eco - friendly features.
• monacos mareterra district was built by project developers who prioritized housing availability in this small nation. they hope to employ mareterras first sustainable and green features in the near future.

Explanation:

1. Analyze Option 1: The passage says Mareterra has housing, so "free of indoor structures" is wrong. Eliminate this option.
2. Analyze Option 2: The passage states past plans got criticism, not Mareterra's caissons. This misrepresents the text. Eliminate.
3. Analyze Option 3: The passage explains Monaco (small area) built Mareterra on artificial land. It also contrasts Mareterra with past projects, noting Mareterra has environmental protections (conservation measures) and eco - friendly features (solar panels, green spaces). This matches the passage's central ideas.
4. Analyze Option 4: The passage says Mareterra already has sustainable features (like solar panels), not that they hope to employ them in the future. Eliminate.

Answer:

Monaco’s Mareterra district provides living space via an artificial land mass. In contrast to previous projects, Mareterra’s design implements conservation measures and promotes eco - friendly features.
