Correcting Verb Tense Errors - GMAT Verbal

One can never say “If I would have done”. One can only say “If I had done”, which is called the past perfect verb form.

The word "thinking" is acting like a participle in the original sentence, making the first clause lack a verb. Changing "Many parents mistakenly thinking" to "Many parents mistakenly think" corrects the sentence's error.

The original statement uses the wrong verb tense for the verb "take"; it should be "took". The correct answer is also more concise than the original.

The original statement erroneously uses the past progressive verb tense "were believing" instead of "believed." The correct answer is also less awkward and more concise than the original.

The use of the verb "learn" is essentially as a modifier of the students "shock." This means that "learning" must be turned into a form that will describe why the students were "shocked." "Were shocked to learn," using an infinitive form, is the best choice among the answers.

The sentence features a conditional statement, "If she arrives empty handed," that explains the underlined portion of the sentence. This means the verb tense in the underlined portion should be in the future, as it will only occur once another action has taken place. "I will be angry," is the correct answer choice.

The use of the phrase "since the nineteenth century" indicates that the appropriate verb form of "sound" must be the past tense, as it describes things taking place previously. The correct answer choice is "has sounded throughout history," as it is the only choice in the past tense.

The opening clause of the sentence notes a "prolonged effort," which indicates the government action has taken place over a long time period. The proper verb will either be in the past tense or show a long amount of time. "The governments reduced" is the best choice among the answers.

The use of "have," a past-tense helping (auxiliary) verb, makes the verb in the sentence past-tense and perfect. However, "sing," a present-tense verb, completes the signaled past perfect form incorrectly and introduces confusion about the sentence's tense. While we could change the verbs in the sentence in many ways to correct the error, only "always sing" is underlined. This means that we can't alter "have," so we need to change "sing" to "sung" to create a correct past perfect verb ("have . . . sung"). The answer choices "always sing" and "sing always" don't correct the sentence's error. "Always sang" may look potentially correct, but "to sing" is an irregular verb in which "sang" is the past tense and "sung" is used in the perfect tense (Example: "She sang the song yesterday, after she had sung the duet."). "Always sang" can't be the correct answer, then, because it incorrectly constructs the past perfect tense. While "always sung" and "sung always" may each look like a potentially correct answer, "sung always" introduces an awkward word order that "always sung" avoids, so "always sung" is the correct answer, making the corrected sentence, "We have always sung anthems that celebrate our nation."

The sentence describes what Transcendentalists did "In the nineteenth century." This indicates the underlined portion of the sentence needs to make use of the past tense, because that part of the sentence is describing the actions that took place "In the nineteenth century." Only "seeking" needs to be changed, as the form "to find" is an infinitive, and does not change regardless of the tense of the verb that precedes it. "Sought to find" is the correct answer choice.

The non-underlined portion of the sentence uses a past tense verb, "took," to describe the general's actions; therefore, the verb in the underlined portion needs to paralllel the form of "took." The correct answer is "While the opposing army slept," as it is the only grammatically correct choice in the past tense.

The underlined portion describes what happened "Previously," which indicates the verb has to be in a tense showing what happened before. The correct answer must be in the past tense, and only "refused to run" has the correct tense among the answers.

The underlined section of the sentence contains both a verb and a preposition, but the only issue lies in the present tense verb. The use of time in the sentence, "after they found out," indicates the celebrations took place in the past. "Began in the school," is the correct answer choice.

Although the verb is next to the singular noun "their father," the subject is actually compound, "The boys and their father," and therefore plural. The correct verb needs to be a plural form. "Eat" is the best choice among the answer choices.

While the underline dportion is a slightly long phrase, the only real grammatical problem is the verb form "speaking," which indicates an active, present verb, when the sentence's construction shows it needs a past tense verd. Therefore, the correct answer is "spoke for a long time on other subjects.."

The underlined phrase takes the form of an infinitive verb phrase, meaning "to remaining" is an incorrect construction. The appropriate form of an infinitive is "to remain," making "to remain popular" the correct answer.

The underlined words make up an incomplete verb phrase, as the verb "become" is in the wrong form. They appropriate version of "become" is the perfect tense, which indicates what has already happened. "Have become popular" is the correct answer choice.

The sentence contains two complete thoughts, separated by the conjunction "which." This means the two verbs in each phrase need to have the same tense. As "spooked" is in the past tense, "Something strange occurred every night of the trip," is the correct answer.

The sentence describes what the soldier had already done to his own body. The use of "himself" is correct and necessary to show who the action was done to, but the action occurred in the past, meaning the appropriate verb form is "backed." The correct answer choice is "had backed himself."
