Editing Tense And Verb ErrorsQuestion 1 of 10

The following paragraph is from a student's academic essay. Read it carefully and answer the question.

"Throughout the nineteenth century, immigrants arrived in American cities and face enormous hardships. They worked long hours in dangerous factories, and many had sent money back to their families in Europe. Meanwhile, labor organizers began to push for better conditions, arguing that workers deserve fair wages and safe environments. The movement grew slowly but eventually gains momentum by the early twentieth century."

Which of the following best describes ALL the verb errors in the paragraph, and which version correctly repairs the most critical tense inconsistency in the final sentence?

The paragraph contains two verb errors: 'face' should be 'faced' and 'deserve' should be 'deserved.' The final sentence is otherwise acceptable because 'gains' can function as a historical present tense to add dramatic effect in academic writing.
The paragraph contains three verb errors: 'face' should be 'faced,' 'deserve' should be 'deserved,' and 'gains' should be 'gained.' The final sentence should read: 'The movement grew slowly but eventually gained momentum by the early twentieth century.'
The paragraph contains two verb errors: 'face' should be 'faced' and 'gains' should be 'gained.' 'Deserve' is correct as a general truth stated in an embedded clause, and the final sentence repair is: 'The movement grew slowly but eventually gained momentum by the early twentieth century.'
The paragraph contains three verb errors: 'face' should be 'faced,' 'had sent' should be 'sent,' and 'gains' should be 'gained.' 'Deserve' is acceptable as a generalization. The final sentence should read: 'The movement grew slowly but eventually gained momentum by the early twentieth century.'

Question 1

The following paragraph is from a student's academic essay. Read it carefully and answer the question.

"Throughout the nineteenth century, immigrants arrived in American cities and face enormous hardships. They worked long hours in dangerous factories, and many had sent money back to their families in Europe. Meanwhile, labor organizers began to push for better conditions, arguing that workers deserve fair wages and safe environments. The movement grew slowly but eventually gains momentum by the early twentieth century."

Which of the following best describes ALL the verb errors in the paragraph, and which version correctly repairs the most critical tense inconsistency in the final sentence?

  1. The paragraph contains two verb errors: 'face' should be 'faced' and 'deserve' should be 'deserved.' The final sentence is otherwise acceptable because 'gains' can function as a historical present tense to add dramatic effect in academic writing.
  2. The paragraph contains three verb errors: 'face' should be 'faced,' 'deserve' should be 'deserved,' and 'gains' should be 'gained.' The final sentence should read: 'The movement grew slowly but eventually gained momentum by the early twentieth century.'
  3. The paragraph contains two verb errors: 'face' should be 'faced' and 'gains' should be 'gained.' 'Deserve' is correct as a general truth stated in an embedded clause, and the final sentence repair is: 'The movement grew slowly but eventually gained momentum by the early twentieth century.' (correct answer)
  4. The paragraph contains three verb errors: 'face' should be 'faced,' 'had sent' should be 'sent,' and 'gains' should be 'gained.' 'Deserve' is acceptable as a generalization. The final sentence should read: 'The movement grew slowly but eventually gained momentum by the early twentieth century.'
Explanation: When editing for verb tense consistency in academic writing, your first job is to identify the dominant time frame of the passage, then check every verb against it. This paragraph is narrating historical events in the simple past, so that's your benchmark. Working through the paragraph, "face" in the first sentence is clearly wrong — it should be "faced" to match the past-tense narrative. "Had sent" in the second sentence is actually correct: the past perfect signals that sending money happened before or during the period being described, making it an appropriate choice. "Deserve" in the labor organizers' argument is a subtle but important case — it appears inside a reported-speech clause expressing a general principle or ongoing belief. In English, general truths and universal statements can remain in the present tense even within past narration, so "deserve" is grammatically defensible. Finally, "gains" in the last sentence is clearly wrong — it breaks tense consistency with "grew" right in the same sentence and should be "gained." That makes C the correct answer: exactly two errors ("face" → "faced" and "gains" → "gained"), with the repaired final sentence reading "The movement grew slowly but eventually gained momentum by the early twentieth century." Choice A fails because it accepts "gains" as a valid historical present, but academic writing reserves that device for consistent stylistic choice — not isolated verb slips mid-sentence. Choice B incorrectly flags "deserve" as an error, misunderstanding how general-truth clauses work. Choice D incorrectly targets "had sent," which is purposeful past perfect, not a mistake. Your strategy: when checking tense consistency, always look within the same sentence first — a tense clash inside one sentence (like "grew...gains") is your strongest signal of an error.

Question 2

The following paragraph is from a student's narrative essay about a personal achievement:

"Finishing my GED was the hardest thing I ever did. I study every night after my children went to sleep, sometimes until two or three in the morning. My husband supported me throughout the process, bringing me coffee and keeping the children quiet. On the morning of the exam, I felt sick with nerves, but I walked into that testing room and I do my best. When the results arrived three weeks later, I cried."

The paragraph contains two verb errors. Which answer correctly identifies BOTH errors, supplies the correct replacement for each, and avoids introducing new errors in the process?

  1. 'Study' should be 'studied' to match the simple past narrative of a completed experience. 'Went' should be 'go' because the sentence 'I study every night after my children went to sleep' requires a consistent present-tense pattern — if 'study' is the error, then 'went' must shift to 'go' to maintain parallel tense in the same clause.
  2. 'Study' should be 'studied' to match the simple past tense established throughout the paragraph. 'Do' should be 'did' because the sentence 'I walked into that testing room and I do my best' clearly describes a past action on the day of the exam, requiring simple past to maintain consistency with 'walked' in the same clause. (correct answer)
  3. 'Study' should be 'studied' to maintain past-tense consistency. 'Went' should be 'had gone' because the children going to sleep preceded the student's studying each night, making past perfect the correct form to show that sequence of events within the narrative.
  4. 'Do' should be 'did' to correct a present-tense intrusion in the past narrative. 'Went' should be 'go' to maintain present-tense consistency with 'study' in the same sentence — both verbs in the clause should share the same tense form regardless of the surrounding narrative frame.
Explanation: When editing a narrative essay for verb tense, your first move is to identify the dominant tense. Here, every sentence is anchored in simple past — "was," "went," "supported," "walked," "arrived" — because the writer is describing a completed experience. Any verb that breaks that pattern is an error. Scanning the paragraph with this lens, two verbs stand out: "study" (present tense in "I study every night after my children went to sleep") and "do" (present tense in "I walked into that testing room and I do my best"). Both should be simple past to match the narrative frame. Replacing "study" with "studied" and "do" with "did" restores consistency without disturbing any other verb. That's exactly what B does, and its reasoning is sound — it ties "did" directly to the coordinating conjunction linking it with "walked," which is a reliable clue that both verbs should share the same tense. A correctly fixes "study" but then wrongly concludes that "went" must change to "go." "Went" is already correct simple past; changing it to "go" would actually create a third error while leaving "do" unfixed. C correctly fixes "study" but replaces "went" with "had gone," claiming past perfect is needed to show sequence. While past perfect can indicate earlier events, it isn't required here — simple past "went" is perfectly natural and is not an error at all. D correctly fixes "do" but then argues "went" should become "go" to match "study." This reasoning treats the error as a feature and compounds it, producing two present-tense verbs in a past-tense narrative. A useful strategy: when you spot one tense error, re-read the entire clause and sentence before deciding whether surrounding verbs also need changing — sometimes they're already correct.

Question 3

Read the following paragraph from a student's argumentative essay:

"The popularity of remote work has transformed the modern office landscape. Before the COVID-19 pandemic, only a small percentage of employees worked remotely on a regular basis. When the pandemic began in 2020, companies around the world were forced to adopt remote work almost overnight. By the time restrictions lifted in many regions, employees had grown accustomed to the flexibility, and many refused to return to full-time office work. Today, hybrid models, in which employees split their time between home and office, became the dominant workplace arrangement in many industries."

A student editor finds one verb error in the final sentence. Which answer correctly identifies the error, provides the right correction, AND explains why every other verb in the paragraph does NOT need to be changed?

  1. 'Became' should be 'have become,' and 'has transformed' in the opening sentence should be changed to 'transformed' to eliminate the use of present perfect in an essay that is otherwise anchored in specific past events. Using both simple past and present perfect in the same paragraph creates the same type of inconsistency that makes 'became' an error.
  2. 'Became' should be 'has become' because 'Today' establishes a present-time frame, and present perfect 'has become' correctly describes a trend that culminated in the past and defines the current state of affairs. All other verbs are correct for the reasons described above, and no further changes are needed to achieve tense consistency throughout the paragraph.
  3. 'Became' should be 'becomes' because 'Today' establishes a present-time frame, and simple present is the appropriate form for describing any current state of affairs. 'Had grown' should also be changed to 'grew' because past perfect is unnecessary when the sequence of events is already made clear by the temporal marker 'by the time restrictions lifted.'
  4. 'Became' should be 'have become' because the sentence begins with 'Today,' anchoring the claim in the present — and present perfect 'have become' correctly connects the past trend of hybrid adoption to its current dominant status, with 'hybrid models' as the plural subject. All other verbs are correct: 'has transformed' (present perfect for an ongoing change with no specified endpoint), 'worked' (simple past for a pre-pandemic habitual state), 'began' (simple past for a specific dated event), 'were forced' (simple past passive for a specific past action), 'had grown' (past perfect for habituation completed before restrictions lifted), and 'refused' (simple past for a specific past behavioral response). (correct answer)
Explanation: When a paragraph mixes multiple time frames, your job as an editor is to ask why each tense is used — not just whether the paragraph "feels consistent." Each tense in academic writing serves a specific logical purpose, and errors occur when a verb's form contradicts the time signal surrounding it. The final sentence opens with "Today," which anchors the claim in the present. The verb "became" is simple past, which signals a completed, finished action — directly contradicting "Today." The fix is "have become," which is present perfect: it describes a trend that developed in the past and remains true now. Because "hybrid models" is plural, the correct form is have become, not has become. This makes D the correct answer, and it also provides the most complete justification for every other verb in the paragraph. Answer A is wrong because it misdiagnoses the paragraph's opening. "Has transformed" is correctly present perfect — remote work's impact on offices is an ongoing, unfinished change with no specified endpoint, so present perfect is appropriate. There is no inconsistency to eliminate. Answer B correctly identifies that "became" needs to change, but prescribes "has become" — a singular form — when "hybrid models" is a plural subject. This subject-verb agreement error disqualifies B. Answer C suggests "becomes" (simple present), which describes permanent, universal truths or routines, not an evolving trend. It also incorrectly targets "had grown" — past perfect is precisely correct here because the habituation was completed before restrictions lifted, making sequence explicit. A useful strategy: whenever you see a time marker like "today," "currently," or "recently," ask whether the verb needs present perfect to bridge past action to present reality — that's one of the most commonly tested distinctions at this level.

Question 4

The following two paragraphs are from a student's personal narrative essay:

Paragraph 1: "When I first arrived in the United States five years ago, I did not speak any English. Every morning, I wake up early and study vocabulary for two hours before my children went to school. My husband worked the night shift, so I was mostly alone during those study sessions."

Paragraph 2: "Now, I am a confident English speaker. I have completed two college courses, and I am planning to transfer to a four-year university next fall. Looking back, I realize that those early morning study sessions had shaped who I am today."

The student's essay contains tense errors that reduce clarity. Which answer correctly identifies ALL errors across both paragraphs?

  1. Paragraph 1 contains one error: 'wake up' should be 'woke up' to maintain the past-tense narrative of five years ago. Paragraph 2 contains one error: 'had shaped' should be 'have shaped' because the shaping influence of those sessions extends into the present, making present perfect more appropriate than past perfect. (correct answer)
  2. Paragraph 1 contains two errors: 'wake up' should be 'woke up,' and 'went' should be 'go' to maintain the habitual present pattern established by 'wake up.' Paragraph 2 contains no errors because past perfect 'had shaped' is acceptable for reflecting on a completed past experience.
  3. Paragraph 1 contains one error: 'wake up' should be 'woke up.' Paragraph 2 contains no errors because 'had shaped' correctly uses past perfect to emphasize that the shaping was fully completed before the speaker's current state of confidence.
  4. Paragraph 1 contains two errors: 'wake up' should be 'woke up,' and 'was' should be 'had been' to show that the aloneness preceded and caused the study habit. Paragraph 2 contains one error: 'had shaped' should be 'have shaped' because the present perfect connects a past action to a present identity.
Explanation: When a personal narrative shifts between a past time period and the present, verb tenses must signal clearly when each action occurred. As you read, ask yourself: "Is this writer describing then, now, or a connection between the two?" In Paragraph 1, the writer is clearly describing a routine from five years ago. The anchor verbs "arrived," "worked," and "went" are all simple past — but "wake up" breaks that pattern. It should be "woke up" to match the past-tense narrative. That is the paragraph's single error. The other verbs ("went," "was") are already correctly in simple past and need no changes. In Paragraph 2, "have completed" and "am planning" are correctly in present or present perfect, reflecting the writer's current reality. However, "had shaped" uses past perfect — a tense typically reserved for an action completed before another past action. Here, the shaping influence of those study sessions still connects to the speaker's present identity. Present perfect ("have shaped") is the right choice because it bridges past experience to current impact. That makes A correct: one error in each paragraph. Answer B is wrong because it claims "went" in Paragraph 1 is an error — it isn't; "went" correctly matches the past-tense context. Answer C wrongly accepts "had shaped" as correct, misapplying past perfect where present perfect is needed. Answer D is wrong on two counts: "was" in Paragraph 1 doesn't require "had been" (no sequencing issue exists there), making its analysis of Paragraph 1 overcomplicated. A useful rule of thumb: use present perfect ("have/has + past participle") when a past event still matters now, and reserve past perfect for showing that one past event preceded another.

Question 5

Read the following excerpt from a student's multi-paragraph argumentative essay:

"Scientists have long studied the effects of sleep deprivation on cognitive function. In a landmark 2003 study, researchers at the University of Pennsylvania recruited 48 volunteers and restricts their sleep to six hours per night for two weeks. By the end of the study period, participants performed as poorly on attention tests as subjects who had been kept awake for 24 hours straight. The researchers concluded that chronic partial sleep loss accumulates into significant cognitive deficits — a finding that continues to influence workplace and school scheduling policies today."

A student editor reviewing this paragraph identifies one verb error. Which answer correctly identifies the error AND explains why the other verbs in the passage do NOT need to be changed?

  1. 'Restricts' should be changed to 'restricted' to match the simple past tense used throughout the narrative of the 2003 study. All other verbs are correct: 'have studied' appropriately signals ongoing relevance, 'had been kept' correctly uses past perfect for an action prior to the comparison point, and 'continues' correctly uses simple present for a finding with current relevance. (correct answer)
  2. 'Restricts' should be changed to 'had restricted' to show that the sleep limitation preceded the measurement of cognitive effects. All other verbs are appropriate given the mixed time frames of the paragraph, and no further changes are needed to improve clarity.
  3. 'Restricts' should be changed to 'restricted,' and 'have studied' should be changed to 'studied' to maintain a fully consistent simple past tense throughout the paragraph, since the present perfect is unnecessary when specific time references like '2003' are present in the same passage.
  4. 'Restricts' should be changed to 'restricted,' and 'continues' should be changed to 'continued' because the final sentence describes the ongoing impact of a past study, which should be expressed in the past tense to maintain consistency with the historical frame of the paragraph.
Explanation: When editing verb tense in academic writing, your job isn't to make every verb match — it's to make every verb accurately reflect when something happened and whether it still matters. This passage intentionally uses multiple tenses because it covers multiple time frames: ongoing scientific practice, a specific past study, and a finding that remains relevant today. The only error is "restricts," which uses third-person simple present instead of simple past. Since the researchers performed this action during the 2003 study — a completed event — it must be "restricted." That's the fix at the heart of answer A, which is correct. Crucially, A also correctly explains why the other verbs stay as they are: "have studied" (present perfect) signals a research tradition that began in the past and continues now; "had been kept" (past perfect) correctly places the comparison subjects' sleep deprivation before the test results being described; and "continues" (simple present) accurately reflects that the finding still influences policy right now. Answer B is wrong because "had restricted" (past perfect) would imply the sleep limitation occurred before some other past event in the sentence — but no such sequencing exists here. Simple past "restricted" is sufficient. Answer C incorrectly insists that "have studied" must become simple past because a year is mentioned nearby. That's a common misconception — present perfect is appropriate when the activity extends to the present, regardless of specific dates elsewhere. Answer D incorrectly changes "continues" to "continued," erasing the real-world, present-day relevance of the research finding. Study tip: When you see multiple tenses in one passage, ask yourself when each action occurs and whether it's still ongoing — tense consistency doesn't mean tense uniformity.

Question 6

The following is an excerpt from a student's analytical essay about a novel:

"In Toni Morrison's Beloved, the character Sethe committed an act of desperate love that haunts the entire narrative. She kills her daughter rather than allow her to be returned to slavery, a decision that isolates her from her community for years. Morrison uses the ghost of the dead child as a symbol of the trauma that refuses to stay buried — both for Sethe personally and for the broader African American experience. The novel ultimately suggested that healing requires confronting, rather than suppressing, the painful truths of the past."

The paragraph contains two verb form errors. Which answer correctly identifies both errors, explains the literary-analysis convention that governs verb tense in this context, and provides appropriate corrections?

  1. 'Committed' should be 'commits' and 'suggested' should be 'suggests' to follow literary present convention. However, 'uses' should also be changed to 'used' because authorial craft decisions — unlike character actions — describe a historical act of writing and may correctly be expressed in the simple past.
  2. 'Committed' should be 'commits' and 'uses' should be changed to 'used' because Morrison's craft decisions are treated as completed past acts of composition and should be expressed in simple past, while character actions like Sethe's killing follow the literary present convention. 'Suggested' is acceptable as written for the same reason.
  3. 'Suggested' should be 'suggests' and 'kills' should be 'killed' to reflect that Sethe's act is presented as a past event within the story's backstory, not an action occurring in the narrative present of the novel, which justifies past tense for backstory events even in literary analysis.
  4. 'Committed' should be 'commits' and 'suggested' should be 'suggests' because literary analysis essays use the literary present tense — the convention that character actions within a fictional narrative and the author's thematic arguments are described in simple present, as if always occurring within the timeless space of the text. 'Kills,' 'isolates,' 'uses,' and 'refuses' are already correctly in the present tense. (correct answer)
Explanation: When you analyze literature in an academic essay, you're expected to use the literary present tense — the convention that everything inside a fictional work exists in a kind of eternal present. Characters always "act," authors always "argue," and themes always "emerge," because the text is always available to be re-read. This rule applies uniformly to character actions, narrator commentary, and authorial craft decisions alike. In the passage, "committed" and "suggested" both break this convention. Sethe "commits" her act every time a reader opens the book; Morrison's novel "suggests" its thematic argument every time it's encountered. The correction is simple: both verbs need the simple present. Meanwhile, "kills," "isolates," "uses," and "refuses" are already correctly written in the present tense — no changes needed there. This makes D the correct answer. Answer A introduces a false distinction, claiming that authorial craft decisions belong in the past tense because writing happened historically. This is a tempting trap, but the literary present applies to an author's choices as expressed in the text — "Morrison uses the ghost" describes something the novel does now, not a moment at Morrison's desk decades ago. Answer B makes the same error as A, misclassifying Morrison's craft decisions as simple past while only partially correcting the character-action verb, leaving "suggested" uncorrected. Answer C goes in the wrong direction entirely, suggesting that backstory events justify past tense. Literary present applies regardless of whether an event is backstory or foreground — if it happens in the novel, it happens in present tense. A reliable tip: in any literary analysis essay, default to present tense for everything — character actions, author choices, and thematic claims — unless you have a specific reason to mark historical time outside the text.

Question 7

The following is an excerpt from a student's process essay about a medical procedure:

"Surgeons perform laparoscopic cholecystectomy using several small incisions rather than one large opening. In a typical procedure, the surgeon first inserted a small camera called a laparoscope into the abdomen, which allowed the surgical team to view the internal organs on a monitor. The surgeon then uses specialized tools to carefully detach the gallbladder from the liver and bile ducts before removing it. After the procedure is complete, the patient typically recovers in one to two days, compared to the week-long recovery required for open surgery."

The paragraph contains tense errors caused by an inconsistent choice of descriptive frame. Which answer most accurately diagnoses the problem and recommends the most effective editorial strategy?

  1. The errors are 'inserted' and 'uses' only. 'Inserted' should become 'inserts' and 'uses' should remain as is, because 'uses' correctly uses simple present to describe the ongoing step, while 'allowed' should be changed to 'allows' for consistency. 'Performed' and 'recovers' are both correct as general-truth statements and require no revision.
  2. The paragraph mixes simple present with simple past. The most effective fix is to standardize all procedural verbs to simple past: change 'perform' to 'performed,' 'uses' to 'used,' 'is' to 'was,' and 'recovers' to 'recovered,' while keeping 'inserted' and 'allowed' as they are, to reflect that the essay is describing a historical development in surgical technique.
  3. The paragraph mixes simple present (used for general, repeatable procedures) with simple past (used for a specific past instance). The most effective fix is to standardize all procedural verbs to simple present: change 'inserted' to 'inserts' and 'allowed' to 'allows,' while keeping 'performs,' 'uses,' 'is,' and 'recovers' as they are, since the essay describes a general medical process rather than a specific past event. (correct answer)
  4. The paragraph's only error is 'inserted,' which should be 'inserts.' 'Allowed' is correct as past tense because it describes the camera's function in relation to the past action of insertion. 'Uses' and 'recovers' are correctly in the present tense, and the paragraph is otherwise consistent in using a general-process frame with minor acceptable variation.
Explanation: When a paragraph describes a general, repeatable process — like a standard medical procedure performed routinely — all procedural verbs should stay in the simple present tense. This is called the "general-process frame," and it signals that the steps described happen regularly, not just once in the past. The moment you mix past-tense verbs into that frame without a good reason, you create tense inconsistency. In this passage, most verbs already use the general-process frame correctly: "perform," "uses," "is," and "recovers" are all simple present. The two errors are "inserted" and "allowed," which accidentally shift into simple past, suggesting a specific past event rather than a routine procedure. Answer C correctly identifies this diagnosis and recommends the targeted fix: change only "inserted" to "inserts" and "allowed" to "allows," leaving the already-correct present-tense verbs untouched. That's the most efficient editorial strategy — fix what's broken, preserve what isn't. Answer A misidentifies the errors. It correctly flags "inserted" but wrongly claims "uses" is an error and mishandles "allowed," which is actually a tense problem, not a correct form. Answer B recommends shifting everything to simple past to describe a "historical development" — but the passage isn't narrating history; it describes standard current practice. Standardizing to past tense would distort the essay's meaning entirely. Answer D claims only one error exists ("inserted") and incorrectly defends "allowed" as acceptable past tense due to its relationship with "inserted" — but tense agreement between subordinate clauses still depends on the paragraph's overall frame, not local verb pairing. When editing process writing, always ask yourself first: Is this describing a general routine or a specific past event? That single question will anchor your tense choices throughout.

Question 8

The following paragraph is from a student's compare-and-contrast essay on two educational philosophies:

"John Dewey, the American philosopher, argued that education should be rooted in practical experience. He believed that children learn best when they are actively engaged with their environment, rather than passively receiving information. His rival, E.D. Hirsch, had disagreed with this approach and insists instead that a shared body of cultural knowledge forms the foundation of an educated citizenry. Both philosophers influenced educational policy throughout the twentieth century, and their debate continues to shape curriculum discussions today."

The paragraph contains a tense error involving the description of Hirsch's position. Which answer correctly identifies the error, provides the right correction, AND accurately explains the grammatical principle involved?

  1. 'Had disagreed' should be 'disagreed' because Hirsch's disagreement with Dewey was a contemporaneous historical position, not an action completed before another past event. 'Insists' should remain as is because it functions as a historical present, adding rhetorical immediacy to Hirsch's ongoing intellectual stance.
  2. 'Had disagreed' should be 'disagreed' because past perfect is inappropriate when two past actions occurred simultaneously or in the same historical period. Additionally, 'insists' should be changed to 'insisted' to maintain simple past consistency with 'disagreed' and the surrounding historical narrative about both philosophers. (correct answer)
  3. 'Insists' should be changed to 'insisted' to correct the inconsistent tense shift, but 'had disagreed' should remain because it correctly signals that Hirsch's philosophical opposition was fully formed before the broader debate between the two figures became publicly recognized in academic circles.
  4. Both 'had disagreed' and 'insists' are acceptable as written: 'had disagreed' frames Hirsch's position as a prior stance, and 'insists' uses the historical present to represent Hirsch's view as timeless and still relevant. The only correction needed is to change 'continues' in the final sentence to 'continued' to maintain past-tense consistency.
Explanation: When you see a tense consistency question in a historical or academic passage, ask yourself: Do the events described occur in the same time frame, or is one clearly completed before another? That distinction determines whether simple past or past perfect is appropriate. In this passage, Dewey and Hirsch are described as intellectual rivals whose positions existed within the same historical period. The past perfect ("had disagreed") would only be correct if Hirsch's disagreement was completed before some other specific past event — but no such sequence exists here. Both philosophers simply held opposing views during the same era. That makes simple past ("disagreed") the right choice. Additionally, "insists" is present tense, which clashes with the surrounding narrative told in simple past. Since the paragraph is recounting historical positions, "insisted" maintains the consistent simple past voice. That reasoning makes B the correct answer. Answer A fails because it correctly fixes "had disagreed" but wrongly defends "insists" as a "historical present." While the historical present is a real literary device, using it selectively mid-paragraph — surrounded by simple past verbs — creates an ungrammatical inconsistency, not rhetorical flair. Answer C gets it backwards: it keeps "had disagreed" while only fixing "insists." As explained above, the past perfect has no logical justification here since no prior completed action is being signaled. Answer D incorrectly defends both errors simultaneously and then targets "continues," which is actually correct — the debate genuinely does continue into the present day, making present tense appropriate in that final sentence. Study tip: When editing for tense in historical narratives, trace every verb in the paragraph. If one tense stands out without a clear reason (sequence, contrast, or deliberate stylistic shift), it's likely your error.

Question 9

Read the following paragraph from a student's academic research summary:

"Researchers have long debated whether bilingualism enhances executive function. A 2010 meta-analysis reviewed 34 studies and concludes that the evidence was mixed. Some studies showed clear cognitive advantages for bilingual individuals, while others find no significant difference between bilingual and monolingual participants. The authors of the meta-analysis recommended that future researchers control for socioeconomic variables, which they believed confounded many of the earlier results."

The paragraph contains exactly two verb errors. Which answer correctly identifies both errors and provides the appropriate correction for each?

  1. 'Concludes' should be 'concluded' to match the simple past narrative of the 2010 study, and 'find' should be 'found' to maintain consistency with the past-tense reporting of study results. 'Believed' and 'confounded' are both correct past-tense verbs in the final sentence. (correct answer)
  2. 'Concludes' should be 'concluded,' and 'was' should be 'is' because the claim that the evidence is mixed refers to an ongoing academic debate, making the present tense more accurate when summarizing research findings in academic writing.
  3. 'Find' should be 'found' to match the past-tense narrative, and 'concludes' should be 'concluded' for the same reason. However, 'believed' should also be changed to 'believe' because the authors' recommendation reflects a general principle that remains true in current research practice.
  4. 'Concludes' should be 'concluded' to maintain past-tense consistency with 'reviewed,' and 'confounded' should be 'confounds' because confounding is a methodological concept stated as a general truth, not a historical event specific to those earlier studies.
Explanation: When editing academic writing for verb tense, your job is to identify the narrative frame — the tense the writer has established — and check whether every verb stays consistent with it. This paragraph is clearly written in the simple past: "researchers have debated," "reviewed 34 studies," "recommended that future researchers..." Any verb describing what that 2010 study did should follow suit. That logic confirms A as the correct answer. "Concludes" is present tense, but it describes a completed action by a past study — it should be "concluded," matching "reviewed." Similarly, "find" is present tense but refers to what those same studies showed, so it should be "found." The final sentence's verbs — "believed" and "confounded" — are already correctly in the simple past, describing the authors' past reasoning about past studies. That gives you exactly two errors, cleanly corrected. B is tempting because academic writing sometimes uses the eternal present (e.g., "Smith argues that...") when summarizing ongoing ideas. But "was mixed" describes the state of evidence as assessed by a specific past study, not a timeless truth — so flipping it to "is" creates inconsistency rather than fixing one. C goes too far. It correctly identifies both errors but then introduces a third "correction," changing "believed" to "believe." The authors' belief was expressed at a specific past moment in their published work; it doesn't need to be generalized to a present-tense principle. D misidentifies the second error. "Confounded" correctly describes what those specific earlier studies experienced historically — it's not a general scientific truth requiring present tense. Study tip: When a passage describes a named, dated study, treat all its reported actions as simple past — resist the eternal-present temptation unless the claim is genuinely universal.

Question 10

The following paragraph is from a student's cause-and-effect essay:

"Urban heat islands form when large areas of natural vegetation are replaced by pavement and buildings, which absorb and retain heat more efficiently than plants. In Phoenix, Arizona, average nighttime temperatures have risen by nearly 4°C since 1970, because the city expanded rapidly and had paved over thousands of acres of desert. City planners now recognize the problem and began implementing green infrastructure programs, such as urban tree canopies and reflective roofing, to mitigate the effect."

Which answer correctly identifies the verb error in this paragraph and explains why it is the ONLY error that needs to be corrected?

  1. 'Had paved' should be 'paved' because the paving occurred at the same time as the city's expansion, not before it, so simple past is more accurate than past perfect. This is the only error; all other verbs correctly reflect present facts, a present perfect trend, or present-tense planning activities that are already underway.
  2. 'Began' should be 'have begun' or 'are beginning' because it follows 'now recognize,' which is in the present tense, creating a tense inconsistency that reduces clarity. This is the only error; 'had paved' correctly uses past perfect to frame the paving as a prior completed cause of the ongoing temperature rise, and 'have risen' correctly uses present perfect for a trend that started in 1970 and continues today. (correct answer)
  3. 'Have risen' should be 'rose' because the sentence includes the specific time marker 'since 1970,' which requires simple past rather than present perfect in standard academic English. This is the only error that affects clarity, and all remaining verbs are used correctly for their respective time frames.
  4. 'Form' and 'absorb' should both be changed to past tense because the opening sentence describes a completed process of urban development, not an ongoing natural phenomenon, making simple past more accurate for cause-and-effect explanations in academic writing.
Explanation: When editing academic writing, your job isn't just to find a problem — it's to find the right problem and confirm that everything else works correctly. This question tests whether you understand how verb tenses signal time relationships in English. The paragraph's real error is "began," which clashes with "now recognize." The word now anchors the sentence in present time, so the verb describing what planners are doing must also be present-tense. "Began implementing" (simple past) implies the action is finished, but the context clearly describes an ongoing initiative. Changing "began" to "have begun" or "are beginning" restores consistency and clarity. This makes B correct — and it correctly validates the other verbs: "have risen" (present perfect) rightly describes a trend that started in 1970 and continues today, while "had paved" (past perfect) logically frames the paving as a completed cause that preceded and explains the ongoing temperature rise. Choice A misidentifies the error. "Had paved" is actually correct — the past perfect appropriately signals that paving happened before the temperature rise became measurable. Calling it wrong reflects a misunderstanding of how past perfect works in cause-and-effect sequences. Choice C makes a common mistake: claiming that "since 1970" requires simple past. In fact, since + a time marker is a classic trigger for present perfect when the effect continues into the present, exactly as used here. Choice D misreads the opening sentences entirely. "Form" and "absorb" describe general, timeless scientific principles — present tense is precisely correct for universal facts. Your study tip: watch for time signal words like now, since, already, and just — they almost always reveal which tense is required.
