Difficulty: MediumInterpreting Continuation and Causal Structural Signals

The computational linguist observed that incorporating syntactic tree constraints into the neural model did not merely improve translation accuracy; furthermore, by explicitly modeling grammatical structure, the architecture ________ a significant reduction in semantic errors.

Which two of the following options, when inserted into the blank, fit the meaning of the sentence as a whole and yield completed sentences that are logically equivalent?

  1. yieldedAnswer
  2. B
    forestalled
  3. generatedAnswer
  4. D
    precluded
  5. E
    portended
  6. F
    presaged

Answer

The two correct choices are 'yielded' and 'generated', as both words indicate that the architectural enhancement directly produced or brought about the reduction in semantic errors.
The sentence uses the additive/continuation signal 'furthermore' following 'did not merely improve', indicating that the second clause reinforces and builds upon the positive outcome of the first. The words 'yielded' and 'generated' both mean produced or brought about, completing the causal chain logically and producing equivalent sentence meanings.

Step-by-Step Solution

1
Analyze sentence structure and structural transition signals.
The semi-colon followed by 'furthermore' and the clause 'did not merely... by explicitly modeling...' signals a positive continuation and causal reinforcement of the primary benefit.
Understanding structural signals determines whether the missing word must carry a positive, negative, or neutral causal meaning.
2
Determine the required contextual meaning and valence of the blank.
The blank requires a verb meaning 'produced', 'brought about', or 'resulted in' a positive reduction in errors.
The model's architectural improvement leads directly to the positive outcome of error reduction.
3
Evaluate option pairs for semantic equivalence and contextual fit.
'Yielded' and 'generated' both accurately express that the architecture produced the reduction. In contrast, 'forestalled'/'precluded' reverse the directional logic, while 'portended'/'presaged' incorrectly introduce speculative forecasting rather than direct causation.
GRE Sentence Equivalence requires choosing two words that create completed sentences with identical meaning.
