Challenge your understanding of ACT English grammar rules with this quiz designed to target key fundamentals like punctuation, subject-verb agreement, pronoun use, and parallel structure. Strengthen your test preparation by tackling questions aligned with the core concepts assessed on the ACT English section.
Which sentence uses correct subject-verb agreement? For example: 'Each of the students __ ready to begin.'
Explanation: The correct subject-verb agreement is 'Each...is,' because 'each' is a singular indefinite pronoun requiring a singular verb. Option A and C incorrectly use plural verbs 'are' and 'were.' Option D uses 'be,' which is not correct in standard English for this context. Option B matches singular subject with singular verb.
Choose the sentence with correct comma usage: 'Before heading to the store __ I made a list.'
Explanation: Introductory clauses like 'Before heading to the store' should be followed by a comma, as shown in option A. Option B omits the necessary comma, making it incorrect. Options C and D incorrectly place commas within or at the start of the phrase, which disrupts sentence flow. Option A is the only grammatically correct choice.
Identify the correctly revised sentence: 'Each employee should submit ___ report by Friday.'
Explanation: 'Each employee' is singular, so the pronoun must also be singular: 'his or her.' Option B uses 'their,' which is plural and can be informal, but not preferred in standard grammar. Option C uses 'they're,' a contraction that does not fit here. Option D uses 'its,' which refers to non-human subjects. Hence, A is correct.
Select the sentence that maintains verb tense consistency: 'Yesterday, I finished my homework and then ___ television.'
Explanation: Because the actions both happened in the past, past tense verbs are required: 'finished' and 'watched.' Option C correctly uses both past tense verbs. Option A uses the present tense 'watch,' which is inconsistent. Option B begins with 'finish,' present tense, and ends with 'watched,' past tense, creating a tense shift. Option D uses a participle 'finishing,' which is incorrect here.
Which sentence shows correct parallel structure? 'My favorite activities are hiking, swimming, and to read.'
Explanation: Parallel structure requires all list items to follow the same format. Option B uses gerunds ('hiking,' 'swimming,' 'reading'), which is correct. Option A breaks the parallelism with 'to read.' Option C and D mix infinitives with gerunds or plain verbs, failing to maintain consistency. Therefore, B is the correct answer.
