Difficulty: MediumSentence Equivalence: Contextual Synonym Pair Selection

Although the preliminary architecture of the quantum computing framework was touted as impervious to thermal noise, subsequent experimental trials revealed that the system was surprisingly __________, suffering significant coherence loss under even minor temperature fluctuations.

Select the two answer choices that, when used to complete the sentence, fit the meaning of the sentence as a whole and produce completed sentences that are alike in meaning.

  1. susceptibleAnswer
  2. vulnerableAnswer
  3. C
    volatile
  4. D
    erratic
  5. E
    resilient
  6. F
    immutable

Answer

The correct answer choices are 'susceptible' and 'vulnerable'.
The transition word 'Although' signals a contrast between the initial expectation ('impervious') and the actual trial results. The subsequent clause elaborates that the system suffers significant coherence loss from minor temperature shifts. The words 'susceptible' and 'vulnerable' both precisely describe a state of being easily affected or harmed by external forces, completing the sentence with equivalent overall meaning.

Step-by-Step Solution

1
Analyze structural pivot signals and sentence polarity.
The sentence begins with the concession word 'Although' and contrasts 'touted as impervious' with the empirical finding in the main clause ('revealed that the system was surprisingly __________').
The contrast signal indicates that the missing word must mean the opposite of 'impervious' (unaffected/immune).
2
Determine the required contextual meaning of the blank.
The target word must mean open to damage, sensitive, or easily affected by thermal noise, as elaborated by 'suffering significant coherence loss'.
The elaboration clause directly defines the nature of the system's weakness.
3
Identify matching synonym pairs among choices.
'susceptible' and 'vulnerable' form a precise contextual synonym pair meaning exposed to harm or easily influenced.
Both words complete the sentence to produce identical, coherent meanings.
