Zorluk: OrtaWord Precision and Clarity

Read the excerpt below and fill in the blank with the single, most precise word that maintains the formal, scientific tone of the passage.

Cevap:Deep within the dense temperate rainforests of the Pacific Northwest, mycologists recently discovered a rare species of fungus capable of breaking down complex synthetic polymers. While earlier researchers assumed that synthetic materials would persist indefinitely in cold soils, experiments demonstrated that this organism can 【degrade】 toxic plastic pollutants into harmless organic compounds in a matter of weeks.

Cevap

The most precise and contextually appropriate word is 'degrade' (or 'decompose').
The word 'degrade' is the most precise choice because it specifically describes the chemical breakdown of polymers into smaller molecules within a formal scientific context.

Adım Adım Çözüm

1
Analyze the sentence context to identify the specific process being described.
The text describes a biological process where a fungus breaks down complex plastic polymers into harmless organic compounds.
Understanding the precise scientific mechanism helps select a verb with the exact intended meaning.
2
Evaluate vocabulary options for precision, tone, and register.
'Degrade' specifically denotes the chemical breakdown of complex molecules into simpler compounds, fitting the scientific register perfectly.
Vague or informal verbs (such as 'destroy' or 'eat') fail to express the technical biological mechanism.
