Read the following passage about the Designing Spaces That Connect Us to Nature and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

Biophilic design has been turning heads and winning hearts by incorporating natural elements into our living and working spaces. This approach recognizes our innate connection to nature and how it affects our well-being. Studies show that exposure to natural light, plants, and natural materials can reduce stress and improve productivity. Many modern architects now integrate gardens, water features, and large windows into their designs. These elements help create environments where people can thrive both mentally and physically. As one designer put it, "We're bringing the outside in to help people feel at home in their skin."

The benefits of biophilic design extend beyond aesthetics. [I] Hospitals with views of nature report faster patient recovery times. Office buildings with natural elements see decreased absenteeism and increased worker satisfaction. [II] Schools incorporating biophilic principles observe improved student concentration and academic performance. [III] Even retail spaces benefit, with customers spending more time and money in naturally-designed environments. These practical advantages explain why biophilic design is gaining momentum across various sectors. [IV]

Implementing biophilic design doesn't require elaborate renovations. Simple changes like adding houseplants, using natural materials, or rearranging furniture to maximize natural light can make significant differences. Even artificial representations of nature, such as nature photography or recordings of birdsong, provide some benefits. The key is creating spaces that stimulate our senses in ways that remind us of natural environments. This approach works in urban apartments, suburban homes, and rural settings alike. As cities grow denser, these natural connections become increasingly valuable for maintaining our psychological health.

Looking ahead, biophilic design will likely become standard practice rather than a luxury option. Climate change concerns are pushing architects to create buildings that not only connect with nature but also protect it. Living walls that purify air, rooftop gardens that reduce energy consumption, and materials that sequester carbon are becoming more common. These innovations represent a shift from merely appreciating nature to actively participating in its preservation. By designing spaces that honor our biological need for natural connection, we create environments that support both human and planetary health for generations to come.
