Target Sentence: "Babies in the United States don't turn one until a full year has passed, babies in Korea are already one year old on the day they are born."
Grammatical Focus: Comma splice resolution and subordinate clause coordination.
Option Analysis:
- Choice A (No Change): Incorrect. Joining two independent clauses with only a comma creates a comma splice.
- Choice B (While babies): Correct. Adding the subordinating conjunction "While" turns the first independent clause into a dependent clause, fixing the comma splice and logically showing contrast.
- Choice C (The fact is that babies): Incorrect. Leaves two independent clauses joined by a comma without a conjunction.
- Choice D (On the one hand, babies): Incorrect. Adds a transitional phrase but does not fix the underlying comma splice between the two main clauses.
Grammar Rule: Two complete sentences (independent clauses) cannot be joined by a comma alone. Fix comma splices using a subordinating conjunction, a semicolon, or a coordinating conjunction (FANBOYS).

Performance Metrics: Marks $0.00$ / $+1.00$ | Time Spent $0\,\text{min}\,55\,\text{s}$ | Global Accuracy $59.81\%$
Grammatical Focus: Punctuation, clause transitions, and logical coordination.
Option Analysis:
- Choice A (No Change): Correct. Maintains the original phrasing and punctuation as intended in the passage context.
- Choice B (clear-cut so traditions): Incorrect. Introduces an unneeded or illogically causal conjunction.
- Choice C (clear-cut and traditions): Incorrect. Unnecessarily adds a conjunction where not required.
- Choice D (clear-cut, traditions): Incorrect. Creates an improper or awkward punctuation boundary.
Grammar Rule: Ensure transitions and punctuation accurately reflect the relationship between clauses without adding unnecessary conjunctions.

Target Sentence Segment: "Since that belief, he was fooled in 1920…"
Grammatical Focus: Preposition selection, idiom, and concise structure.
Option Analysis:
- Choice A (No Change - "Since that belief"): Incorrect. "Since" is unidiomatic when used to describe a state of belief prior to an action; "since" indicates time elapsed from a point.
- Choice B ("for") / Choice C ("in"): Incorrect. Expressions like "for that belief" or "in that belief" are non-standard and unidiomatic in this context.
- Choice D (Delete the highlighted portion): Correct. Deleting the awkward phrase produces a concise, direct, and grammatically standard sentence.
Grammar Rule: Eliminate non-standard prepositional phrases and wordiness when deleting the phrase clarifies the sentence.

Performance Metrics: Marks $0.00$ / $+1.00$ | Time Spent $0\,\text{min}\,21\,\text{s}$ | Global Accuracy $60.89\%$
Grammatical Focus: Nominative (subject) vs. objective pronoun case and reflexive pronoun misuse.
Option Analysis:
- Choice A (No Change) / Choice D (her cousin and her): Incorrect. Uses objective case ("her") as part of the sentence subject.
- Choice B (her cousin and herself): Incorrect. Reflexive pronouns ("herself") cannot function as simple subjects without a subject antecedent in the same clause.
- Choice C (she and her cousin): Correct. Uses the nominative subject pronoun ("she") required for the subject of the verb.
Grammar Rule: Test compound subjects by removing the second person (e.g., "she returned" vs. "her returned"). Reflexive pronouns (-self/-selves) should never be used as compound subjects.

Performance Metrics: Marks $0.00$ / $+1.00$ | Time Spent $0\,\text{min}\,25\,\text{s}$ | Global Accuracy $20.46\%$
Grammatical Focus: Verb tense consistency, aspect, and passive voice in historical narration.
Option Analysis:
- Choice A (No Change): Correct. Preserves the original verb phrasing consistent with the tense structure established in the text.
- Choice B (were actually): Incorrect. Alters the intended tense or aspect unnecessarily.
- Choice C (were actually being): Incorrect. Uses unnecessary passive continuous phrasing ("were being"), introducing awkward wordiness.
- Choice D (have actually been): Incorrect. Present perfect tense ("have been") incorrectly implies an action that continues into the present.
Grammar Rule: Maintain consistent tense and aspect suited to the surrounding text.
