Form, Structure, and Sense: Practice Questions & Study Guide
Applying correct verb tense, subject-verb agreement, pronoun-antecedent agreement, modifier placement, and parallel structure to produce grammatically precise sentences.
Understanding Form, Structure, and Sense
Form, Structure, and Sense is the broader grammar subtopic, covering a range of conventions that ensure sentences are internally consistent and logically coherent. The most heavily tested areas are: verb forms (tense, agreement, and mood), pronoun usage (antecedent agreement and case), and sentence-level conventions like modifier placement and parallel structure. Unlike sentence boundary questions—which have clear structural rules—Form, Structure, and Sense questions often require reading the entire sentence carefully for meaning before selecting the correct form.
Subject-verb agreement is the single most-tested convention in this subtopic. The test creates difficulty by separating the subject from the verb with long intervening phrases: 'The results of the decade-long study on urban heat islands [was/were] published last year.' The subject is 'results' (plural), but the intervening phrase 'of the decade-long study on urban heat islands' misleads students into selecting 'was.' The reliable fix: cross out everything between the subject and the verb, identify the subject, and check its number.
Verb tense and form questions present sentences where multiple tenses are grammatically possible, and you must choose the one consistent with the passage's timeline and context. Common patterns: the passage establishes a past timeline and asks you to identify whether the verb should be simple past, past perfect, or past progressive; or the passage describes a general truth or scientific fact that requires the simple present. The key is reading context clues—time markers, other verbs in the passage, and logical sequence.
Pronoun-antecedent agreement, modifier placement, and parallel structure questions round out this subtopic. For pronouns, the antecedent must be clear and the pronoun must match in number and person—'everyone' is singular and takes 'his or her' (or 'their' in informal usage, which the test now accepts). For modifiers, a participial phrase at the start of a sentence must describe the sentence's grammatical subject. For parallel structure, items in a list or compound construction must be in the same grammatical form.
Key Rules & Formulas
Memorize these rules — they come up directly in practice questions.
Cross out intervening phrases to identify the true subject before checking verb agreement.
'The bouquet of tulips and lilies [needs/need] to be arranged.' Cross out 'of tulips and lilies'—subject is 'bouquet' (singular), so 'needs' is correct.
Pronouns must match their antecedents in number—collective nouns (team, committee, company) are typically singular on the test.
'The committee made its decision' (singular) not 'their decision' in formal test contexts.
An introductory participial phrase must modify the grammatical subject of the main clause.
Wrong: 'Rushing to meet the deadline, the report was hastily written.' Right: 'Rushing to meet the deadline, the team hastily wrote the report.' (the team, not the report, was rushing).
Parallel structure: items in a list or after a correlative conjunction (both…and, either…or, not only…but also) must be in the same grammatical form.
'The program helps students to improve their grades, develop time management skills, and [building/build] confidence.' Parallel infinitives require 'build,' not 'building.'
Use the subjunctive mood (were, be, have been) for hypothetical, contrary-to-fact, or demanding constructions.
'If the temperature were to drop below freezing, the pipes would burst.' (subjunctive 'were,' not 'was,' because this is hypothetical.)

The following sentence contains a blank. Select the choice that best completes the sentence according to the conventions of Standard English. The team of researchers ______ their findings at the annual conference in April.
Show explanation
Correct answer: B. presents
Explanation
The subject of the sentence is 'team,' a collective noun that is singular when acting as a unit. 'Of researchers' is a prepositional phrase that modifies 'team' but is not the subject. Since the subject is singular ('team'), it requires a singular verb. In the simple present tense, the singular third-person form is 'presents.' Choice B is correct. Choice A ('present') is plural. Choice C ('are presenting') uses a plural auxiliary 'are' with a singular subject. Choice D ('have presented') uses a plural auxiliary 'have' and changes the tense to present perfect without contextual justification.
The following sentence contains a blank. Select the choice that best completes the sentence according to the conventions of Standard English. By the time the expedition reached base camp, the supplies ______ significantly depleted by three days of unexpected storms.
Show explanation
Correct answer: C. had been
Explanation
The signal phrase 'by the time the expedition reached base camp' establishes a past time reference with a completed-before-arrival sequence. When one past action is completed before another past action, the earlier action takes the past perfect tense ('had been'). The depletion happened before the arrival at base camp—so 'had been depleted' is the correct form. Choice A ('are') is present tense, inconsistent with the past context. Choice B ('were') is simple past, which can describe past events but does not capture the 'completed before' timing. Choice D ('have been') is present perfect, which refers to a past action with relevance to the present—inconsistent with the past narrative here.
The following sentence contains a blank. Select the choice that best completes the sentence according to the conventions of Standard English. ______ through the museum's archives for months, the curator discovered a collection of photographs that had never been publicly exhibited.
Show explanation
Correct answer: A. Having searched
Explanation
The sentence needs an introductory participial phrase that correctly modifies the subject of the main clause—the curator. 'Having searched through the museum's archives' is a perfect participial phrase indicating that the searching was completed before the discovery, and it correctly modifies 'the curator' (the grammatical subject immediately following the comma). Choice A is correct. Choice B ('After searching') is also grammatically acceptable—it creates an adverbial phrase—but Choice A more precisely conveys completion before the discovery. Choice C ('The search') makes 'the search' the subject of the introductory phrase, but the main clause's subject is 'the curator'—this creates a dangling modifier because the search did not discover the photographs; the curator did. Choice D makes the introductory element an independent clause, creating a run-on.
The following sentence contains a blank. Select the choice that best completes the sentence according to the conventions of Standard English. The committee recommended that each applicant ______ a portfolio of original work along with the standard application materials.
Show explanation
Correct answer: C. submit
Explanation
The verb 'recommended' triggers the subjunctive mood in the dependent clause introduced by 'that.' In English, verbs of recommendation, suggestion, demand, or requirement (recommend, suggest, insist, require, demand, propose) require the base form of the verb (the present subjunctive) in the 'that' clause, regardless of number or tense. The base form is 'submit'—no -s ending, no tense inflection. Choice C is correct. Choice A ('submits') is the indicative singular present, not the subjunctive. Choice B ('submitted') is past tense, incorrect for the required construction. Choice D ('will submit') is future tense, which does not follow the subjunctive pattern.
The following sentence contains a blank. Select the choice that best completes the sentence according to the conventions of Standard English. Neither the lead architect nor the two junior engineers ______ aware of the structural flaw until the inspection report was filed.
Show explanation
Correct answer: B. were
Explanation
With 'neither...nor' constructions, the verb agrees with the subject closest to it (the rule of proximity). The subjects joined are 'the lead architect' (singular) and 'the two junior engineers' (plural). The subject closest to the verb is 'the two junior engineers'—plural. Therefore, the verb must be plural: 'were.' Choice B is correct. Choice A ('was') would be correct if the singular subject 'the lead architect' were closest to the verb. Choice C ('has been') uses a singular auxiliary 'has' and present perfect tense, both incorrect here. Choice D ('is') is present tense and singular, doubly incorrect.
The following sentence contains a blank. Select the choice that best completes the sentence according to the conventions of Standard English. The company's success depended not only on ______ but also on building a culture that attracted and retained top engineers.
Show explanation
Correct answer: B. developing innovative products
Explanation
The 'not only...but also' correlative conjunction requires parallel grammatical form on both sides. The second element is 'building a culture'—a gerund phrase. Therefore, the first element must also be a gerund phrase: 'developing innovative products.' Choice B maintains parallel structure with 'building' in the second element. Choice A ('to develop') is an infinitive, not a gerund—it breaks parallelism. Choice C ('the development that was innovative') is a noun phrase with a relative clause—it breaks parallelism with 'building a culture.' Choice D ('innovative products were developed') is a full clause with a passive verb—grammatically incompatible with the parallel structure required.
The following sentence contains a blank. Select the choice that best completes the sentence according to the conventions of Standard English. The novel's narrator, along with her two unreliable companions, ______ the reader through a series of increasingly ambiguous flashbacks.
Show explanation
Correct answer: B. guides
Explanation
The subject of the sentence is 'narrator'—singular. The phrase 'along with her two unreliable companions' is a parenthetical phrase (not joined by 'and') that does not change the number of the subject. 'Along with,' like 'as well as' and 'in addition to,' introduces supplementary information but does not create a compound subject. The subject remains singular ('narrator'), requiring the singular verb 'guides.' Choice B is correct. Choice A ('guide') is plural. Choice C ('are guiding') uses the plural auxiliary 'are.' Choice D ('have guided') uses the plural auxiliary 'have' and present perfect tense.
The following sentence contains a blank. Select the choice that best completes the sentence according to the conventions of Standard English. If the atmospheric carbon dioxide concentration ______ at its pre-industrial level, many of the climate disruptions observed today would not have occurred.
Show explanation
Correct answer: C. had remained
Explanation
This is a past contrary-to-fact conditional: carbon dioxide did not remain at pre-industrial levels, and the climate disruptions did occur. In third conditional (past contrary-to-fact) constructions, the if-clause uses the past perfect ('had + past participle') and the main clause uses 'would have + past participle.' The sentence's main clause is 'would not have occurred'—the correct past perfect form for the if-clause is 'had remained.' Choice C is correct. Choice A ('remained') is simple past, which is used in second conditional (present contrary-to-fact) structures, not third conditional. Choice B ('remains') is present tense, inconsistent with the past context. Choice D ('has remained') is present perfect, also inconsistent with the past contrary-to-fact structure.

Common Mistakes to Avoid
These are the most frequent errors students make on Form, Structure, and Sense questions. Knowing them in advance prevents costly point losses.
- !Choosing a verb that agrees with the nearest noun rather than the actual grammatical subject (proximity agreement error).
- !Using a plural pronoun ('they,' 'their') for a singular antecedent because the antecedent feels general, without checking whether the test context allows informal singular 'they'—check each question carefully.
- !Misidentifying the subject of a dangling modifier by reading the sentence quickly rather than checking which noun immediately follows the introductory phrase.
- !Breaking parallel structure by shifting form within a list (mixing gerunds, infinitives, and noun phrases).
- !Using 'was' instead of 'were' in hypothetical or contrary-to-fact conditionals because 'was' sounds more natural in casual speech.
Strategy Tips: Form, Structure, and Sense
For any question involving a verb, identify the subject first by asking 'who or what is performing this action?' Cross out all intervening material before deciding on number agreement.
For pronoun questions, identify the antecedent (the noun the pronoun replaces) and check: same number? same person? unambiguous (only one possible antecedent)?
For parallel structure, read the list aloud substituting each answer choice in turn—the correct choice will sound rhythmically and grammatically consistent with the other items.
For modifier questions, find the introductory phrase, identify what it describes, and then check whether the grammatical subject of the main clause is that thing—if not, the modifier is dangling and you need to correct the subject.
