When a revision does not fit the passage
CHAPTER 18
When a revision does not fit the passage
Two revision choices can both sound acceptable when read alone. Put each one back into the paragraph and identify the relationship the sentence has to preserve. The correct choice must fit the passage and preserve the intended meaning.
Name the revision problem before comparing choices
Before comparing four revision options, name what kind of problem the sentence actually has: a purpose mismatch, an overstated claim, a misplaced modifier, an organizational gap, or a punctuation error. Naming the problem first narrows which options are even plausible.
Test each choice inside the paragraph
A revision option that reads acceptably on its own can still fail once placed back inside its actual paragraph. Test a candidate revision by rereading the surrounding sentences with that option in place, not by evaluating the option in isolation.
Find the relationship the sentence must preserve
Every sentence sits inside a web of relationships: what it depends on, what depends on it, what it is evidence for, what claim it must not exceed. A correct revision preserves these relationships; an incorrect one, even if fluent, breaks at least one of them.
Grammatically correct can still be wrong here
A revision option can be entirely free of grammatical errors and still be the wrong answer, because grammatical correctness and rhetorical fit are different standards. A grammatically perfect sentence that serves the wrong purpose, or that appears in the wrong place in the argument, is still wrong for that specific question.
Recognize a revision that overstates the claim
A revision that sounds more confident or more dramatic than the original is not automatically an improvement. Check whether the new wording claims more than the passage's evidence supports before treating a stronger-sounding option as the better one.
Reject a smoother sentence with the wrong purpose
Some incorrect options are smoother or more elegant than the correct answer. Fluency is not the deciding factor on a writing question. A smoothly worded sentence that does not do the job the passage needs at that point is still the wrong choice.
Break a tie by changing the least
When two revisions are grammatical and both sound reasonable, return to the exact problem named by the stem. Compare what each option changes in purpose, scope, evidence, tone, and logical connection. The stronger choice fixes the stated problem while disturbing the fewest other relationships the passage needs. A smoother sentence that also changes the claim is not an improvement.

EXAM DIAMOND When two choices both sound fine, identify the one problem the question is testing. Choose the option that fixes that problem without creating a new one. |
CONSTRUCTED-RESPONSE DRILLS
Drill 1: Diagnose the smoother-but-wrong revision
A proposal argues that a city should extend library hours because working parents and students are underserved. A student revises the concluding sentence to read: “In a world where time is our most precious resource, every library must rise to meet the moment.”
Explain why this smoother, more dramatic sentence is the wrong revision, using the language of purpose and traceable relationship.
Model reasoning: This revision is fluent but overstates the passage's actual, modest claim and shifts to a sweeping statement about “every library,” far beyond the one specific library the proposal addresses. The passage's purpose is a concrete, local request, and this revision abandons that purpose for a vague, inflated generalization that no longer connects to the specific evidence the proposal built.
Drill 2: Diagnose the grammatically correct but misplaced revision
A petition for a new crosswalk states its case for four paragraphs, then a student inserts, between the second and third paragraphs, the grammatically correct sentence: “The city was founded in 1889 along the river.”
Explain why this sentence is wrong for this location in the passage, even though it contains no grammatical error.
Model reasoning: This sentence is grammatically correct but has no rhetorical fit at this point in the passage; it does not extend the safety argument, respond to a concern, or supply evidence for the claim being built in the surrounding paragraphs. Its problem is purpose and organization, not grammar, since inserting unrelated historical background interrupts the developing argument.
CHAPTER 18 PRACTICE
This set uses four writing passages from earlier chapters. Each question asks you to diagnose a specific revision choice. Answer all twenty questions before checking explanations.
Set 1
“I am writing to request that the Elmwood Public Library extend its weekday hours until 8:00 p.m. Currently, the library closes at 6:00 p.m., a schedule that misses two groups of residents who need it most: working parents and high school students.”
Original passage: letter to a town council (from Chapter 12)
Set 2
“Riverside Middle School switched to a four-day school week two years ago. Since then, Riverside has reported a 15 percent drop in staff turnover. Based on this result, our district should seriously consider piloting a four-day week.”
Original passage: proposal to a school district (from Chapter 14)
Set 3
“The Riverbend Apartments complex opened eighteen months ago and now houses over four hundred residents. The nearest bus stop on Route 12 is currently a fifteen-minute walk from the complex's main entrance. Extending Route 12 by three-quarters of a mile would bring the bus stop within a five-minute walk.”
Original passage: petition to a regional transit authority (from Chapter 15)
Set 4
“The city began composting collection last month. Participation has already exceeded expectations. Officials cite three benefits: reduced landfill waste, lower collection costs, and cleaner recycling streams.”
Original passage: city newsletter update (from Chapter 17)
Question 1
- AA. It contains a grammatical error
- BB. It replaces the letter's specific, actionable request with a vague general statement, abandoning the letter's actual purpose
- CC. It contradicts information later in the letter
- DD. It is too short for an opening sentence
Question 2
- AA. It overstates the claim; the passage's evidence concerns two specific groups, not every resident
- BB. It uses more sophisticated vocabulary and is therefore an improvement
- CC. It is grammatically incorrect
- DD. It removes necessary punctuation
Question 3
- AA. It changes the letter's central request
- BB. It removes necessary evidence
- CC. It shifts the letter's audience
- DD. It creates a comma splice by joining two independent clauses with only a comma
Question 4
- AA. It fixes a parallel structure problem in the original
- BB. It corrects a misplaced modifier
- CC. It overstates the claim by adding an unsupported category, “everyone else in town,” that the passage's evidence does not address
- DD. It removes redundant wording
Question 5
- AA. It has no effect on the passage's argument
- BB. It fixes a redundancy problem
- CC. It corrects an overstated claim
- DD. It removes the specific claim the following evidence is designed to support, breaking the relationship between the claim and its evidence
Question 6
- AA. It contains a grammatical error
- BB. The confrontational tone is not well suited to a persuasive letter addressed to a governing body the writer is trying to convince
- CC. It removes necessary evidence
- DD. It creates a misplaced modifier
Question 7
- AA. It uses more confident, assertive language and is therefore stronger
- BB. It contains a subject-verb agreement error
- CC. It overstates the claim far beyond what a single comparable school's result can support
- DD. It removes necessary evidence
Question 8
- AA. It is the better choice because it sounds more persuasive
- BB. It contains a comma splice
- CC. It fixes a parallel structure problem
- DD. It overstates the claim as “clear and obvious” based on a single school's result, when the passage's own evidence supports only a claim worth piloting
Question 9
- AA. It has no effect on the passage's organization
- BB. It removes the need for the Riverside evidence entirely
- CC. It establishes the district's own problem before introducing outside evidence, letting the reader understand why the Riverside example is relevant from the start
- DD. It corrects a grammatical error in the original ordering
Question 10
- AA. It overstates the recommended action, skipping the piloting stage the evidence's limited scope actually supports
- BB. It uses simpler vocabulary and is therefore clearer
- CC. It creates a dangling modifier
- DD. It fixes an inconsistency in the original
Question 11

Question 13
- AA. It makes the sentence more persuasive to officials evaluating the petition
- BB. It corrects a factual error in the original
- CC. It fixes an unclear pronoun reference
- DD. It replaces precise, verifiable evidence with vague, subjective language, weakening rather than strengthening the passage's credibility with transit officials
Question 14
- AA. This reordering would have no effect on the passage
- BB. The five-minute-walk claim depends on the reader already knowing the current fifteen-minute walk, so reversing the order removes the necessary baseline for comparison
- CC. This reordering would fix a grammatical error
- DD. This reordering would strengthen the passage's persuasive case
Question 15
- AA. It overstates both the strength of the evidence and the certainty of the required action, exceeding what a modest, local walking-distance case can support

- DD. It fixes a redundancy problem in the original conclusion
Question 16
- AA. It fixes a comma splice in the original
- BB. It overstates the passage's claim

Question 17
- AA. It replaces measured, professional language with vague, exaggerated wording inappropriate for a factual city newsletter update
- BB. It makes the sentence more persuasive and is therefore an improvement
- CC. It fixes a subject-verb agreement error
- DD. It corrects a misplaced modifier
Question 18
- AA. It changes the passage's central claim

- DD. It fixes an inconsistency in the original three benefits
Question 20
- AA. It adds necessary detail the original lacked
- BB. It breaks the parallel structure of the list by shifting the third item to a full clause while the first two remain noun phrases
- CC. It fixes a comma splice
- DD. It corrects an overstated claim
ANSWERS AND EXPLANATIONS
Show the answers and explanations
1. Correct answer: B
A: This sentence is grammatically correct; its problem is purpose and specificity, not grammar.
B (correct): The original opening states a specific request; this revision retreats into generic commentary about libraries in general, failing to do the job an opening sentence in a request letter needs to do.
C: This sentence does not contradict anything later; it simply fails to state the letter's actual purpose at the point where an opening needs to.
D: Length is not the issue; the issue is that the sentence fails to state the specific request, regardless of how long or short it is.
2. Correct answer: A
A (correct): The evidence that follows names two specific groups, working parents and students; claiming the schedule fails “every single resident” extends the claim well beyond what the passage's actual evidence supports.
B: Vocabulary sophistication does not make a revision correct; the deciding factor is whether the claim's scope matches the evidence, which this revision fails to do.
C: This sentence is grammatically correct; its problem is that it overstates the claim beyond what the evidence supports.
D: This revision does not involve a punctuation problem; the issue is the overstated scope of the claim.
3. Correct answer: D
A: The request itself remains the same in this combination; the problem is a punctuation error, not a change in the letter's purpose.
B: No evidence is removed in this combination; both original pieces of information remain, just incorrectly punctuated together.
C: The intended audience, the town council, is unaffected by this sentence combination; the problem is purely a punctuation error.
D (correct): Both halves of this combined sentence are independent clauses; joining them with only a comma, rather than a semicolon or coordinating conjunction, creates a comma splice.
4. Correct answer: C
A: The original list was already parallel; this revision does not fix a structural problem, and instead introduces an unsupported overstatement.
B: No modifier placement issue exists in the original phrase; this revision introduces an overstatement problem instead.
C (correct): The passage's evidence specifically concerns two named groups; adding “everyone else in town” extends the claim to a population the evidence does not actually address.
D: This revision adds words rather than removing redundancy, and the added content creates a scope problem rather than solving a wordiness problem.
5. Correct answer: D
A: Cutting this phrase would measurably affect the passage by removing the claim its following evidence depends on.
B: This phrase is not redundant; it states a specific, necessary claim that the passage's evidence goes on to support.
C: This phrase, as originally written, is an appropriately scoped claim, not an overstatement in need of correction.
D (correct): This phrase sets up the specific claim, about two affected groups, that the following sentence's evidence directly supports; cutting it would leave that evidence without the claim it is meant to prove.
6. Correct answer: B
A: This sentence is grammatically correct; its problem is tone and audience fit, not grammar.
B (correct): A letter aiming to persuade a town council benefits from a respectful, evidence-based tone; “frankly absurd” shifts to a confrontational register that could undermine the letter's persuasive credibility with this specific audience.
C: No evidence is removed here; the problem is the tone's mismatch with the letter's persuasive purpose and audience.
D: No modifier placement issue exists in this revision; the problem is tone, not modifier placement.
7. Correct answer: C
A: Confident wording does not make a claim correct; a confident overstatement is still an overstatement that outruns the evidence.
B: This sentence is grammatically correct; its problem is the scope of the claim, not grammar.
C (correct): One school's two-year result cannot guarantee an outcome for every future staffing problem in a different district; this revision claims certainty the evidence does not provide.
D: No evidence is removed here; the problem is that the claim built on the existing evidence has become disproportionate to it.
8. Correct answer: D
A: Sounding persuasive is not the deciding standard; a claim's scope must still match its evidence, which this revision fails to do.
B: This sentence does not contain a comma splice; its problem is an overstated claim, not a punctuation error.
C: There was no parallel structure problem in the original sentence; this revision introduces an overstatement problem instead.
D (correct): Despite sounding more decisive, this revision claims a certainty, “clear and obvious,” that a single comparable school's result cannot support; smoother phrasing does not fix the underlying scope problem.
9. Correct answer: C
A: This reordering does affect the passage's organization by changing which idea, the district's problem or the outside evidence, a reader encounters first.
B: The Riverside evidence remains necessary regardless of this reordering; the reordering changes sequence, not the need for evidence.
C (correct): Establishing the district's own need first gives the reader a reason to care about the Riverside evidence before encountering it, rather than presenting evidence for a problem not yet established.
D: The original ordering contained no grammatical error; the reordering is a matter of organizational effectiveness, not grammatical correctness.
10. Correct answer: A
A (correct): A single comparable school's result supports a claim about the value of testing the approach, not skipping directly to full implementation without further discussion.
B: Vocabulary simplicity is not the issue here; the issue is that the claim's scope of action has been overstated beyond what the evidence supports.
C: No modifier placement issue exists in this revision; the problem is an overstated recommendation, not modifier placement.
D: The original phrase was not inconsistent; this revision introduces a new overstatement problem rather than fixing an existing one.
11. Correct answer: A
A (correct): The evidence concerns a specific walking-distance reduction near one bus stop; claiming the extension would solve “every transportation problem” vastly exceeds what this specific evidence can support.
B: Confidence is not the deciding factor; a confidently overstated claim is still an overstatement that outruns the evidence.
C: This sentence does not contain a misplaced modifier; its problem is the scope of the claim, not modifier placement.
D: No evidence is removed here; the problem is that the claim has become disproportionate to the evidence already presented.
12. Correct answer: C
A: The claims themselves remain unchanged in this combination; the problem is a punctuation error, not a change in meaning.
B: No evidence is removed in this combination; both original pieces of information remain, just incorrectly punctuated together.
C (correct): Both halves of this combined sentence are independent clauses; joining them with only a comma, rather than a semicolon or coordinating conjunction, creates a comma splice.
D: The intended audience, the transit authority, is unaffected by this sentence combination; the problem is purely a punctuation error.
13. Correct answer: D
A: Vague, subjective language is generally less persuasive than specific, verifiable data to officials evaluating a request based on evidence.
B: Nothing suggests the original fifteen-minute figure is inaccurate; the substitution does not correct an error but instead removes useful precision.
C: No pronoun reference issue exists in this phrase; the problem is the loss of precise, verifiable evidence.
D (correct): The specific figure, fifteen minutes, is exactly the kind of precise evidence that supports the petition's claim; replacing it with the subjective “incredibly long and grueling” removes verifiable precision without adding real persuasive force for an official audience.
14. Correct answer: B
A: This reordering would measurably affect the passage by removing the baseline comparison the improvement claim depends on.
B (correct): The improvement claim only makes sense as a comparison to the current walking time; presenting it before that baseline is established would leave the reader without the necessary context to understand the improvement.
C: There is no grammatical error in the original ordering; the issue with reordering is a logical dependency problem, not grammar.
D: This reordering would weaken, not strengthen, the passage by removing the necessary context for understanding the claimed improvement.
15. Correct answer: A
A (correct): Describing local walking-distance evidence as “overwhelming” and claiming the authority has “no choice” regardless of cost overstates both the evidence's strength and the certainty of the necessary action.
B: Sounding urgent is not the deciding standard; a claim's scope and certainty must still match its evidence, which this revision fails to do.
C: This sentence is grammatically correct; its problem is an overstated claim, not a grammatical error.
D: There was no redundancy problem in the original conclusion; this revision introduces an overstatement problem instead.
16. Correct answer: D
A: The original sentence contained no comma splice; this revision replaces a correctly used colon with a less appropriate comma.
B: This revision does not change the claim's scope at all; it only changes punctuation, introducing a structural error.
C: No evidence is removed in this revision; all three benefits remain listed, just with less appropriate punctuation introducing them.
D (correct): “Officials cite three benefits” is a complete independent clause, making the colon the grammatically appropriate choice to introduce the list; the comma does not perform this same clear structural signal.
17. Correct answer: A
A (correct): A city newsletter reporting program results benefits from measured, credible language; “beyond anyone's wildest dreams” shifts to hyperbole that does not fit the passage's informational purpose and register.
B: Persuasiveness through hyperbole is not the standard for a factual newsletter update; measured, credible language better serves this passage's actual purpose.
C: The original sentence contained no subject-verb agreement error; this revision introduces a tone problem instead.
D: No modifier placement issue exists in the original sentence; this revision introduces a tone and register problem instead.
18. Correct answer: C
A: The claims themselves remain unchanged in this combination; the problem is a punctuation error, not a change in meaning.
B: No evidence is removed in this combination; both original pieces of information remain, just incorrectly punctuated together.
C (correct): Both halves of this combined sentence are independent clauses; joining them with only a comma, rather than a semicolon or coordinating conjunction, creates a comma splice.
D: This combination does not change the scope of any claim; the problem is purely a punctuation error.
19. Correct answer: A
A (correct): The original passage claims only “reduced” landfill waste as one of three general benefits; claiming the program “guarantees” complete elimination within a specific timeframe vastly exceeds what this evidence supports.
B: Adding a specific but unsupported timeframe does not create genuine precision; it creates an unsupported, overstated claim instead.
C: This sentence does not contain a dangling modifier; its problem is the scope of the claim, not modifier placement.
D: The original three benefits were not inconsistent; this revision introduces a new overstatement problem rather than fixing an existing one.
20. Correct answer: B
A: This revision does not add meaningful new information; it only changes the grammatical form of the third item, creating an inconsistency.
B (correct): The first two items are parallel noun phrases; shifting the third item to a full clause, “the streams are cleaner for recycling,” breaks the grammatical consistency the list needs.
C: The original list contained no comma splice; this revision introduces a parallel structure problem instead.
D: The original third item was not an overstatement; this revision introduces a structural problem rather than correcting a scope issue.
