Drill 83: Explaining a Claim's Evolution
Explain live whether a claim's change across a passage is refinement or contradiction — the spoken mirror of Lesson 83.
Learning Objectives
By the end of this drill, you should be able to:
- State live whether a claim change is refinement or contradiction
- Apply the 'can both be true at once' test out loud, under time pressure
- Justify the judgment in the same breath as making it
Introduction
Lesson 83 gave you a specific test for telling refinement apart from contradiction: can both statements be true at once? This drill asks you to run that test live, out loud, on a claim that shifts across a passage — the kind of judgment call a real conversation about a report demands in the moment, not after time to think.
Shadow the Model
The first claim says clearance time was cut in half. But later, it turns out that only applied to low-risk shipments — everything else stayed the same. That's not a refinement, that's a contradiction.
Notice "that's not a refinement, that's a contradiction" is said as one confident unit — a fluent speaker doesn't hedge the judgment once they've made it.
Your Turn
Your Turn
Section 1 of a report claims customs clearance time was cut in half. Section 4 reveals the cut only applied to low-risk shipments — for everything else, nothing changed. When the timer starts, say out loud whether this is refinement or contradiction, and justify it in one breath.
Say your judgment now — refinement or contradiction, and why
Record Yourself
Say your judgment and justification, then record it and compare against the model answer.
Model Answer
Show a model answer
There's no single correct wording, but a strong answer sounds like: "This is a contradiction, not a refinement — the first claim implied a general effect, but it turns out the reduction only held for a small group of shipments, so the original claim isn't defensible as stated." What matters is stating the judgment first, then justifying it immediately, without a long pause in between.
