A city council member argues that expanding late-night bus service is a practical safety measure: it reduces drunk driving, gives hospital staff reliable rides, and keeps service workers from walking long distances after midnight. In the draft below, the writer wants to revise the bolded sentence for clarity.
Because the buses run only until 11 p.m., which is when many restaurant shifts end, riders are forced into paying for rideshares or walking home, both options are expensive or unsafe.
Which revision best improves clarity while preserving original meaning?
Because buses stop running at 11 p.m.—when many restaurant shifts end—riders must either pay for rideshares or walk home, options that are expensive or unsafe.
Buses run only until 11 p.m., and many restaurant shifts end then, which forces riders into paying for rideshares or walking home, and those options are expensive or unsafe for them.
Because riders are forced into paying for rideshares or walking home, both options are expensive or unsafe, the buses run only until 11 p.m., when many restaurant shifts end.
Because the buses run only until 11 p.m., which is when many restaurant shifts end, riders are forced into paying for rideshares or walking home, both options being expensive or unsafe.
Explanation
This question tests using grammar and mechanics for clarity by asking you to revise a sentence with multiple structural issues. The correct answer (B) improves precision and readability by using dashes to set off the parenthetical information "when many restaurant shifts end," creating a cleaner flow than the original's awkward "which is when" construction. Additionally, choice B eliminates the confusing phrase "both options being expensive or unsafe" by directly stating "options that are expensive or unsafe," making the relationship between the two alternatives clearer. Choice A's dangling phrase "both options being expensive or unsafe" creates ambiguity about what exactly is expensive or unsafe. The key strategy is to identify parenthetical elements and use appropriate punctuation (dashes, commas, or parentheses) to integrate them smoothly while maintaining clear subject-verb-object relationships.
In a review of a documentary on food waste, the author argues that confusion over date labels causes unnecessary disposal. The author notes that “best by” dates indicate quality, not safety, for many shelf-stable foods. The draft sentence reads: "People throw away food that is still safe, because the label sounds like a deadline." Which change best improves readability?
People throw away food that is still safe, because the label, sounds like a deadline.
People throw away food that is still safe; because the label sounds like a deadline.
People throw away food, that is still safe, because the label sounds like a deadline.
People throw away food that is still safe because the label sounds like a deadline.
Explanation
This question tests using grammar and mechanics for clarity by eliminating unnecessary punctuation. The original sentence incorrectly places a comma before "because," which disrupts the natural flow of the causal relationship. Choice A fixes this by removing the unnecessary comma, allowing the causal clause to connect directly to the main clause. The revision improves readability by following standard punctuation rules where restrictive clausal modifiers don't require comma separation. Choices B, C, and D add incorrect punctuation marks that create confusion or break the logical connection between the action and its reason. Clear causal relationships flow smoothly without unnecessary punctuation interrupting the logical connection.
In an essay about consumer habits, the author argues that “fast fashion” is cheap at checkout but expensive in environmental costs. The author cites a report estimating that textile production generates more emissions than international flights and shipping combined. The draft includes: "A $10 shirt looks like a bargain, until you count the water, dyes, and landfill space." Which revision best improves clarity while preserving original meaning?
A $10 shirt looks like a bargain, until counting the water, dyes, and landfill space.
A $10 shirt looks like a bargain; until you count the water, dyes, and landfill space.
A $10 shirt looks like a bargain until you count the water, dyes, and landfill space.
A $10 shirt looks like a bargain, until you count the water, dyes and landfill space.
Explanation
This question tests using grammar and mechanics for clarity by eliminating unnecessary punctuation. The original sentence incorrectly places a comma before "until," which disrupts the natural flow of the sentence from the main clause to the subordinate clause. Choice A fixes this by removing the unnecessary comma, allowing the sentence to flow naturally from "looks like a bargain" to the qualifying condition "until you count..." The revision improves readability by following standard punctuation rules where subordinate clauses beginning with "until" don't require comma separation. Choices B, C, and D either retain the unnecessary comma or add incorrect punctuation that creates confusion. Clear sentences avoid unnecessary punctuation that interrupts the logical flow from main ideas to qualifying conditions.
In an essay about student athletics, the author argues that sports can support academics when schedules protect study time. The author mentions a team policy requiring phones off during supervised homework hour, after which failing grades decreased. The draft sentence reads: "The policy worked because it was consistent, not because it was strict." Which revision best improves clarity while preserving original meaning?
The policy worked because it was consistent, not strict, because it was.
The policy worked because it was consistent, not because it was strict.
Because it was consistent, the policy worked, not because it was strict.
The policy worked because it was consistent and not strict.
Explanation
This question focuses on using grammar and mechanics for clarity by improving sentence structure and emphasis. The original sentence places the key contrast at the end, but Choice C restructures it to emphasize the causal relationship more clearly by fronting the dependent clause. Moving "Because it was consistent" to the beginning creates better emphasis on the reason for success, while the main clause "the policy worked" gets appropriate focus. The "not because it was strict" contrast flows more naturally at the end. Choices A, B, and D either maintain less effective structure or create grammatical errors. Strategic sentence structure can improve emphasis and logical flow of ideas.
In a column about household energy use, the author argues that smart thermostats help only when paired with realistic schedules. The author cites utility data showing the biggest savings occurred when users set consistent nighttime setbacks. The draft sentence reads: "A smart thermostat can save energy, if people actually program it." Which change best improves readability?
A smart thermostat, can save energy if people actually program it.
A smart thermostat can save energy, if people, actually program it.
A smart thermostat can save energy, if people actually program it, though.
A smart thermostat can save energy if people actually program it.
Explanation
This question addresses using grammar and mechanics for clarity by eliminating unnecessary punctuation. The original sentence incorrectly places a comma before a conditional clause beginning with "if," which disrupts the natural flow of the conditional statement. Choice A fixes this by removing the unnecessary comma, allowing the conditional clause to connect smoothly to the main clause. The revision improves readability by following standard punctuation rules for conditional statements. Choices B, C, and D add more unnecessary commas or awkward phrasing that create choppiness and grammatical confusion. Clear conditional statements flow naturally without unnecessary punctuation interrupting the logical connection between condition and result.
In a sustainability newsletter, the author argues that repairing electronics should be easier because it reduces waste. The author notes that a local repair cafe diverted 430 pounds of devices from the landfill in six months. The draft sentence reads: "Right-to-repair laws don’t force anyone to fix a phone, they just remove obstacles." Which revision best improves clarity while preserving original meaning?
Right-to-repair laws don’t force anyone to fix a phone, and they just remove obstacles, basically.
Right-to-repair laws don’t force anyone to fix a phone, removing obstacles.
Right-to-repair laws don’t force anyone to fix a phone; just removing obstacles.
Right-to-repair laws don’t force anyone to fix a phone; they just remove obstacles.
Explanation
This question focuses on using grammar and mechanics for clarity by correcting comma splice errors. The original sentence incorrectly joins two independent clauses with only a comma, creating a comma splice that disrupts the logical contrast being presented. Choice A fixes this by replacing the comma with a semicolon, which properly connects the two independent clauses about what right-to-repair laws don't do versus what they actually accomplish. The semicolon maintains the contrast while providing correct punctuation that helps readers understand the distinction between forcing action and removing barriers. Choices B, C, and D either create sentence fragments, add unnecessary wordiness, or retain grammatical errors. Proper punctuation between contrasting independent clauses clarifies the logical relationship.
In a health column, the author argues that sunscreen use is a daily habit, not just a beach-day precaution. The author notes that UVA rays penetrate clouds and windows. The draft includes: "Sunscreen matters on overcast days, the damage is cumulative." Which revision best improves clarity while preserving original meaning?
Sunscreen matters on overcast days; because the damage is cumulative.
Sunscreen matters on overcast days, the damage being cumulative.
Sunscreen matters on overcast days, because the damage is cumulative.
Sunscreen matters on overcast days because the damage is cumulative.
Explanation
This question addresses using grammar and mechanics for clarity by correcting comma splice errors. The original sentence incorrectly joins two independent clauses with only a comma, creating a comma splice that disrupts the logical connection between the two health facts. Choice A fixes this by replacing the comma with "because," which creates a proper dependent clause that explains why sunscreen matters on overcast days. The revision transforms the comma splice into a clear cause-and-effect relationship while maintaining the original meaning about UV damage accumulation. Choices B, C, and D either retain improper punctuation or create sentence fragments that obscure the causal relationship. Converting comma splices into properly subordinated clauses clarifies logical relationships.
In a personal essay about volunteering, the author argues that service is most valuable when it is sustained rather than episodic. The author compares one-day “drive-by” events with a weekly tutoring commitment that lasted a year. The draft includes: "I learned names over time, this changed charity into relationship." Which revision best improves clarity while preserving original meaning?
Learning names over time, this changed charity into relationship.
I learned names over time, and this changed charity into relationship, which it did.
I learned names over time; this changed charity into relationship.
I learned names over time, this having changed charity into relationship.
Explanation
This question tests using grammar and mechanics for clarity by correcting comma splice errors. The original sentence incorrectly joins two independent clauses with only a comma, creating a comma splice that disrupts the narrative flow about personal transformation. Choice A fixes this by replacing the comma with a semicolon, which properly connects the two independent clauses about learning names and how this changed the relationship dynamic. The semicolon maintains the causal relationship while providing correct punctuation that allows readers to understand the connection between the action and its effect. Choices B, C, and D either retain grammatical errors or create new structural problems that obscure the personal insight being shared. Proper punctuation helps readers follow personal narrative development.
In a commentary about nutrition labels, the author argues that front-of-package warnings help shoppers compare products quickly. The author cites a study where participants identified high-sodium foods more accurately when warnings were present. The draft sentence reads: "Front-of-package labels are useful, for shoppers who are in a hurry." Which change best improves readability?
Front-of-package labels, are useful, for shoppers who are in a hurry.
Front-of-package labels are useful for shoppers who are in a hurry.
Front-of-package labels are useful, and for shoppers who are in a hurry.
Front-of-package labels are useful, for the shoppers, who are in a hurry.
Explanation
This question addresses using grammar and mechanics for clarity by eliminating unnecessary punctuation. The original sentence incorrectly places a comma before a prepositional phrase ("for shoppers who are in a hurry"), which disrupts the natural flow of the sentence. Choice A fixes this by removing the unnecessary comma, allowing the prepositional phrase to flow naturally from the main clause. The revision improves readability by following standard punctuation rules for essential prepositional phrases. Choices B, C, and D add more unnecessary commas or conjunctions that create choppiness and grammatical errors. Clear writing avoids unnecessary punctuation that interrupts the natural flow of essential sentence elements.
In a piece about scientific literacy, the author argues that uncertainty is not a weakness but a feature of honest research. The author explains that confidence intervals communicate what data can and cannot claim. The draft includes: "Scientists revise conclusions when new evidence appears, this is how knowledge grows." Which revision best improves clarity while preserving original meaning?
Scientists revise conclusions when new evidence appears, and this is how knowledge grows, which is.
Scientists revise conclusions when new evidence appears; this is how knowledge grows.
Scientists revise conclusions when new evidence appears, this being how knowledge grows.
Scientists revise conclusions, when new evidence appears this is how knowledge grows.
Explanation
This question addresses using grammar and mechanics for clarity by correcting comma splice errors. The original sentence incorrectly joins two independent clauses with only a comma, creating a comma splice that disrupts the explanation of scientific progress. Choice A fixes this by replacing the comma with a semicolon, which properly connects the two independent clauses about scientists revising conclusions and how this represents knowledge growth. The semicolon maintains the explanatory relationship while providing correct punctuation that allows readers to understand how the revision process contributes to scientific advancement. Choices B, C, and D either retain grammatical errors or create awkward phrasing that obscures the connection between scientific revision and progress. Proper punctuation helps readers follow logical explanations of complex processes.
