Task 83: Tracking a Claim's Evolution
Write a paragraph tracking what changed about a claim across a passage — and whether that change is legitimate refinement or genuine contradiction — the writing mirror of Lesson 83.
Learning Objectives
By the end of this task, you should be able to:
- Track a claim's certainty, scope, or causal strength as it changes across a passage
- Distinguish refinement (the author adding precision) from contradiction (the author correcting themselves)
- State clearly what changed and why it counts as one or the other
Introduction
Lesson 83 taught you to track a claim across a whole book, asking after every section: did its certainty rise or fall, did its scope narrow, was a limit added? And it gave you a specific test for telling refinement apart from contradiction. This task asks you to apply that test in writing, to a claim that changes across a short passage.
The Rule, for Writing
Core Concept
Refinement adds precision without denying the earlier claim — "ports save time" becomes "ports save time, mainly above a certain volume." Contradiction denies what was said before — "ports save time" becomes "ports do not actually save time." The test: can both statements be true at once? If yes, it's refinement. If no, it's contradiction.
Example
"Early evidence suggested the new schedule cut delays." Later: "on closer inspection, the delay reduction was mostly seasonal, not caused by the new schedule." These cannot both be fully true — the second statement denies the causal claim of the first. That's contradiction, not refinement, even though the author states it politely.
Your Turn
Your Turn
Section 1 of a report claims: "the new customs process reduced clearance time by half." Section 4 states: "on closer inspection, the reduction only applied to shipments already flagged as low-risk; for all other shipments, clearance time stayed the same." Write a paragraph tracking what changed about the claim — its scope, its certainty — and say clearly whether this is refinement or contradiction, using the test above.
Vocabulary in Context
refineverbformal
to add precision to a claim without denying it (পরিমার্জন করা)
Often with refine a claim, refine the argument, further refine
“The later chapters refine the claim without abandoning it.”
on closer inspectionphraseformal
a signal phrase marking that a claim is about to be corrected or narrowed (গভীরভাবে পর্যবেক্ষণ করলে)
Often with on closer inspection, upon closer inspection, after closer inspection
“On closer inspection, the improvement applied only to export cargo.”
Model Answer
Show a model answer
Section 1 claims a broad win: customs clearance time was cut in half. Section 4 narrows the scope drastically — the reduction only held for shipments already flagged low-risk, and for everything else, nothing changed. Applying the test: can both statements be true at once? No — "clearance time was cut in half" implies a general effect, but Section 4 shows the effect applied to a small subset of shipments, not the whole process. This is a contradiction dressed as a refinement: the scope shrank so much that the original claim is no longer defensible as stated.
Self-Check
Self-Check
- Did you correctly identify this as contradiction rather than refinement?
- Did you apply the "can both be true at once" test explicitly?
- Did you cite the specific words that mark the scope change?
