If the text does not explicitly state it, it is . If you want to practice further, let me know: Which specific question number gave you the most trouble? worms put new life into derelict site reading answers
Mastering these contextual words will help you ace similar environmental science passages: Abandoned, ruined, or neglected.
The use of microorganisms/worms to clean up contaminated soil. If you are preparing for a reading test,
Heavy machinery crushes the soil structure, eliminating the pore spaces required for air and water circulation.
The article focuses on an innovative environmental project in the UK aimed at reclaiming "brownfield" sites—derelict, industrially contaminated land. Traditional cleanup methods involve completely removing toxic soil and hauling it to landfills, which is expensive and disruptive. If the text does not explicitly state it, it is
The process that earthworms can accelerate is called _____.
Researchers at Bell College of Technology found that these specialized worms accelerate soil formulation within a mixture of waste and sewage, a process that would otherwise take 60 years. These earthworms improve soil structure through feeding and aeration. Simultaneously, 250,000 alder and willow trees were planted to extract contaminants. The project aims to be self-financing through the sale of harvested wood, providing a sustainable, cost-effective solution compared to the estimated £30 million for traditional cleanup methods. Key Vocabulary & Paraphrasing
Microorganisms — The stimulation of these organisms accelerates the natural decontamination process.
Why do these answers matter beyond the test? The passage is based on real research from the late 2000s and early 2010s, particularly studies from Newcastle University (UK) and the US EPA.
