Difficulty: MediumContrast and Reversal Clues

Which of the following words best completes the sentence?

  1. doctrinaireAnswer
  2. B
    vacillating
  3. C
    tentative
  4. D
    fastidious
  5. E
    diffident

Answer

The word 'doctrinaire' correctly completes the sentence by establishing the required semantic reversal between the archaeologist's unyielding public stance and her flexible private thoughts.
The sentence uses the contrast signals 'Paradoxically' and 'while' to set up an opposition between the archaeologist's public behavior and her private field journals. Since her private journals show 'persistent doubts' and a 'willingness to revise', her public posture must be the opposite—inflexible, unyielding, and dogmatic. 'Doctrinaire' precisely describes an uncompromising, dogmatic stance, making it the correct fit.

Step-by-Step Solution

1
Identify structural contrast signals
The sentence begins with 'Paradoxically, while...', indicating that the public posture in the first clause must contrast with the private feelings in the second clause.
Contrast pivots dictate that the blank must carry the opposite valence/meaning of the clues in the non-blank clause.
2
Analyze context clues in both clauses
The second clause describes 'persistent doubts and a remarkable willingness to revise her core hypotheses', supported by the modifying phrase 'refusing to concede even minor points'.
The blank describes a public attitude characterized by extreme stubbornness and refusal to admit error or compromise.
3
Evaluate option definitions against the required meaning
'Doctrinaire' specifically means stubbornly asserting opinions or dogmatic beliefs without flexibility, making it the exact antonymic match for 'willingness to revise'.
Only 'doctrinaire' fulfills both the definition of being unyielding in debate and the structural requirement of contrasting with private open-mindedness.

Key Concept

Identifying structural contrast signals ('while', 'paradoxically') to establish semantic reversal across sentence clauses.
