TEAS 7 English Practice Test

1. If the word antibacterial describes a substance that kills bacteria, you can infer that the prefix anti-means:

Correct answer: B

Rationale: The correct answer is 'B: Against.' The prefix 'anti-' means 'against,' as seen in the word 'antibacterial,' which denotes something that acts against bacteria. Choice A, 'Original to,' is incorrect as the prefix 'anti-' does not imply 'original to.' Choice C, 'Before,' is incorrect as 'anti-' does not signify 'before' but rather 'against.' Choice D, 'Under,' is also incorrect as 'anti-' does not convey the idea of being 'under' but rather 'against' in this context.

2. What is the main verb tense in the following sentence? 'She had already left before I arrived.'

Correct answer: D

Rationale: The correct answer is 'D, Past perfect tense.' In the sentence provided, the verb 'had left' is in the past perfect tense. The past perfect tense is used to indicate an action that was completed before another past action, which in this case is 'arrived.' Therefore, the main verb tense in the sentence is past perfect. Choices A, B, and C are incorrect because the sentence does not contain present, past, or future tense verbs as the main verb. Instead, the main verb 'left' is in the past perfect tense, showing an action completed before another past event.

3. What is the complete subject in the sentence: Sandra’s principal reason for choosing the job was that it would be full-time and would offer benefits?

Correct answer: A

Rationale: The complete subject in a sentence includes all the words that describe the main focus of the sentence. In this case, the complete subject is "Sandra’s principal reason for choosing the job" as it encompasses all the relevant details about Sandra and her reason for selecting the job. Choice A is the correct answer because it provides the most comprehensive and specific information, making it the complete subject. Choices B, C, and D are incorrect as they do not include all the necessary elements to form the complete subject and do not convey the full context of the sentence.

4. Which of the following sentences shows the correct way to separate the items in the series?

Correct answer: C

Rationale: Option C is the correct answer as it correctly separates the cities and states in the series using commas. The items in a series should be separated by commas, with the final two items being separated by 'and.' Choices A, B, and D have incorrect punctuation or lack necessary commas. In Choice A, semicolons are used incorrectly, and in Choice B, semicolons are placed inappropriately. Choice D lacks necessary commas to separate the cities and states effectively. Therefore, Option C is the only choice that demonstrates the correct way to separate items in a series.

5. Which of the following sentences correctly uses subject-verb agreement?

Correct answer: B

Rationale: The correct answer is B because it maintains subject-verb agreement. In this sentence, 'she is' agrees with 'the lead scientist,' and 'does' agrees with 'she.' Choices A, C, and D have subject-verb agreement errors. In choice A, 'write' should be 'writes' to match the singular subject 'The lead scientist,' and 'does' should be 'do' to match the plural 'scientists in the group.' Choice C also has the same subject-verb agreement error as A. In choice D, 'do the research' should be 'does the research' to match the singular 'every scientist in the group.'
