Which of the following words, if inserted into the blank, best completes the sentence?

  1. obtainAnswer
  2. B
    acquire
  3. C
    falter
  4. D
    flourish
  5. E
    forfeit

Answer

The correct choice is 'obtain'.
The word 'obtain' in its intransitive form means to be prevalent, customary, or established. In the passage context, it accurately describes how traditional analytical methods remain in place despite modern advancements.

Step-by-Step Solution

1
Analyze the structural clues and context of the sentence.
The opening concession 'While modern computational techniques...' sets up a contrast, but the main clause emphasizes that traditional methods 'still ________ ... where long-standing observational protocols continue to be strictly observed.'
The blank requires a verb meaning to exist, prevail, or hold true in a specific domain.
2
Evaluate the vocabulary options against secondary definitions.
The verb 'obtain' has a secondary, intransitive definition meaning to be prevalent, customary, or in force (e.g., 'the rule still obtains').
This secondary meaning fits both the syntax and the precise logical tone required by the context.
