Read the following passage about Boyan Slat's Revolutionary Approach to Ocean Cleanup and mark the letter A, B, C or D on your answer sheet to indicate the option that best fits each of the numbered blanks from 18 to 22.

Boyan Slat's revolutionary vision for oceanic restoration emerged during his teenage years following a transformative diving experience in Greece. (18)_________, humanity might have continued ignoring this environmental crisis indefinitely. His subsequent establishment of The Ocean Cleanup at eighteen demonstrated remarkable entrepreneurial courage. System 001, the organization's pioneering device, (19)_________, represents a technological breakthrough in marine conservation. The innovation employs sophisticated floating barriers equipped with underwater skirts designed to intercept debris while preserving aquatic ecosystems.

The challenge extends beyond mere collection; the retrieved materials require sustainable processing. Transportation logistics, recycling infrastructure, and market development for recovered plastics pose formidable obstacles. His groundbreaking proposition, (20)_________, reflects visionary environmental leadership rivaling established conservationists. These microscopic fragments infiltrate food chains irreversibly, threatening both marine biodiversity and human health. His ambitious scaling strategy envisions deploying numerous autonomous systems throughout global garbage patches.

Critics question economic viability and potential ecological disruptions, yet supporters emphasize urgency given accelerating pollution rates. Prevention remains paramount; cleanup constitutes damage control. (21)_________. Whether this approach achieves meaningful impact depends on technological refinement, funding sustainability, and international cooperation. Nevertheless, Slat's initiative has catalyzed global awareness, (22)_________.

Question 20:

A. whereby governments facilitate extensively through marine ecosystems proliferating with beneficial microparticles

B. that humanity must act decisively before larger plastics disintegrate into irrecoverable microparticles

C. what corporations prioritize consistently remains profitable ventures emerging from biodegradable microparticles

D. whether scientists validate hypothetically before organic compounds synthesize into reversible microparticles

Question 21:

A. The organization's reluctance to processing salvaged materials into temporary products undermines environmental sustainability goals

B. The organization's commitment to converting salvaged materials into durable products demonstrates circular economy principles

C. The organization's strategy involves exporting salvaged materials to developing nations rather than domestic manufacturing

D. The organization's focus remains exclusively on collection while ignoring recycling possibilities and product development

Question 22:

A. delaying necessary innovations and policy reforms concerning plastic pollution practically rather than theoretically

B. hindering parallel innovations and policy reforms by creating plastic pollution competition rather than cooperation

C. inspiring parallel innovations and policy reforms addressing plastic pollution systematically rather than superficially

D. replacing traditional innovations with policy reforms ignoring plastic pollution temporarily rather than permanently
