Exercise 7 - Part 3
Use the word given in CAPITALS and brackets to form a word that fits in the gap.
Engineers have long looked to nature for inspiration, a field of study known as (0) biomimicry (MIMIC). Nature’s designs are the result of millions of years of evolutionary (1) (REFINE), solving complex problems with maximum efficiency. For instance, the aerodynamic shape of bullet trains was modeled after the beak of a kingfisher, reducing noise (2) (SUBSTANCE). Similarly, synthetic materials mimicking sharkskin are being developed for their (3) (BACTERIA) properties. These innovations offer highly (4) (EFFECT) alternatives to traditional, chemically altered surfaces. Furthermore, studying how termites regulate mound temperatures has led to the creation of energy-efficient buildings, reducing the (5) (RELY) on air conditioning. The potential applications of this science seem virtually (6) (END). As ecological concerns become more pressing, biomimicry provides (7) (ENVIRONMENT) friendly solutions. It reminds us that nature holds answers to our most (8) (TROUBLE) technological challenges.
