Identifying the Most Relevant Addition to an Argumentative Passage

Read the following passage and answer the question that follows:

In the realm of modern architecture, sustainability has emerged as a paramount concern. Architects and designers are increasingly tasked not only with creating aesthetically pleasing spaces but also with ensuring that these environments minimize their ecological footprint. This shift has led to innovations such as green roofs and energy-efficient materials, which contribute to the reduction of waste and energy consumption.

However, the integration of sustainable practices often raises issues of cost. Critics argue that while the benefits of sustainable architecture are clear, the initial financial investment can deter many clients, particularly in economically strained communities. Conversely, proponents maintain that the long-term savings on energy and maintenance can offset these initial costs, ultimately leading to a net positive outcome for both developers and the environment.

This debate is further complicated by the evolving standards and regulations in the construction industry that aim to promote sustainable practices. As policies become more stringent, the emphasis on eco-friendly design increases, compelling architects to innovate and adapt.

Ultimately, the question remains: will the move towards sustainability become a standard practice in the architectural industry, or will economic factors continue to impede progress?
