Read the following translated transcript from a Spanish-language science podcast titled 'Sustainable Innovation':
'Welcome to Sustainable Innovation. Today we analyze a pioneering architectural project in Jalisco, Mexico. Initially, many critics argued that bioplastics would be the absolute future of sustainable construction. However, the lead researcher, Dr. Elena Torres, maintains a different perspective. "The true breakthrough is not in plastics, but in mycelium," Torres states. She details that they grow building blocks using corn stalks and fungal spores over fourteen days. During my visit to the laboratory, I assumed that the greatest technological challenge would be getting the material to achieve the structural strength of concrete. Interestingly, the doctor instantly corrected me: "Compression and structural resistance are achieved naturally within the first week of growth. Our true technical obstacle was stopping the organic growth without using toxins; we achieved this through a rapid baking process at 85 degrees Celsius." Finally, to solve the problem of external moisture, they apply an agave-based resin. Although the press frequently highlights the astonishing strength of these blocks as the project's main achievement, for the scientific team, the critical innovation lies exclusively in that thermal deactivation process.'
Which of the following best describes the primary technical challenge that the scientific team had to overcome, according to Dr. Elena Torres?
- Finding a non-toxic method to halt the biological development of the fungus.Cevap
- BProving that bioplastics are the fundamental material for the future of sustainable construction.
- CEnsuring that the mycelium blocks reached a strength level superior to traditional concrete.
- DDeveloping an agave-based resin to protect the building structures from environmental moisture.
