Zorluk: OrtaAnalyzing Contextual Tone and Valence Clues

Although preliminary environmental surveys predicted that the introduction of the non-native vine would have a ________ effect on the indigenous forest ecosystem, long-term monitoring demonstrated that native species adapted quickly and experienced virtually no decline. Which TWO of the following answer choices, when inserted into the blank, produce completed sentences that are logically coherent and alike in meaning?

  1. deleteriousCevap
  2. detrimentalCevap
  3. C
    innocuous
  4. D
    salutary
  5. E
    transient
  6. F
    catastrophic

Cevap

The correct choices are 'deleterious' and 'detrimental'.
The sentence structure uses the concession signal 'Although' to contrast the initial prediction with the observed outcome. Since the long-term observation showed native flora experiencing 'virtually no decline', the initial prediction must have anticipated a negative or harmful impact. The words 'deleterious' and 'detrimental' both mean harmful or damaging, perfectly filling the blank with equivalent negative valence and logical coherence.

Adım Adım Çözüm

1
Analyze structural transition signals and contextual clues.
The sentence begins with the concession pivot 'Although', indicating a contrast between the preliminary surveys' prediction and the actual findings from long-term monitoring.
Pivot words set up direct opposition between clauses.
2
Determine the required valence of the blank.
The second clause reveals that native species 'adapted quickly and experienced virtually no decline' (a positive/harmless outcome). Therefore, the initial prediction in the blank must express a negative or harmful valence.
The contrast requires the prediction to be opposite in polarity to the harmless outcome.
3
Evaluate option pairs for semantic equivalence and contextual fit.
'Deleterious' and 'detrimental' both mean causing harm or damage, fitting the negative valence precisely and producing equivalent sentence meanings.
Sentence Equivalence items require selecting two words that complete the sentence with identical meaning.
