Para Summary — quick quiz

Paragraph: Biomimicry—design inspired by biological systems—has yielded innovations from Velcro (modeled on burrs) to bullet trains shaped like kingfisher beaks to reduce noise. Yet the field faces limitations. Evolution optimizes for survival, not human engineering goals like cost-efficiency or scalability. A spider's silk may be remarkably strong, but industrial replication proves prohibitively expensive. Furthermore, biological solutions often require specific environmental conditions absent in human applications. Despite these constraints, biomimicry remains valuable for generating novel approaches to design challenges. Which option best summarizes the paragraph?
