Part B: Provide Passage Architecture & Core Elements
Main Point: A new immunotherapy treatment has shown remarkably successful results that exceeded researchers' expectations.
Argument Flow: The passage presents evidence of surprising success (94% tumor regression, no side effects, quick results) leading to a conclusion about what this demonstrates.
Step 2: Interpret the Question Precisely
This is a fill-in-the-blank question asking us to choose the best logical connector. The answer must create the right relationship between what comes before and after the blank.
Step 3: Prethink the Answer

- When a treatment performs this well and surprises researchers, we need a word that captures how well the treatment works
efficacy
Efficacy
✓ Correct
- Means effectiveness or ability to produce desired results
- Perfectly matches the 94% success rate evidence
ambiguity
Ambiguity
✗ Incorrect
- Means being unclear or confusing
- Contradicts the clear, definitive results shown
volatility
Volatility
✗ Incorrect
- Means being unstable or unpredictable
- Goes against the consistent success across patients
obscurity
Obscurity
✗ Incorrect
