[1] In the mid-1980s, French botanist Patrick Blanc revolutionized urban architecture by popularizing the *mur végétal*, or vertical garden. [2] Unlike traditional ivy-covered walls, which can damage brickwork with their roots, Blanc's design uses a structural frame, a PVC layer, and a felt lining that supports plants without soil. [3] The felt is continuously irrigated with nutrient-rich water, allowing a diverse array of species to thrive. [4] Today, his towering green walls cover the facades of museums, shopping centers, and private residences worldwide, offering both aesthetic beauty and natural insulation.
The writer is considering adding the following sentence to the end of the paragraph (after sentence [4]):
'Some of these plants, such as certain species of ferns and mosses, require high levels of humidity to survive.'
Should the writer make this addition?
- AYes, because it provides necessary details about the specific types of vegetation most commonly utilized in Blanc's structural design.
- BYes, because it supports the explanation of the irrigation system described in sentence [3].
- No, because it interrupts the paragraph's discussion of the structural design and benefits of the vertical gardens with a tangential detail about the care of specific plants.Answer
- DNo, because it contradicts the information in the paragraph regarding the soil-free environment of the green walls.
