Select the word or phrase that makes the following sentence grammatically correct: Sometimes, the condition.............with an unusual symptomĀ"vertigo.
- A. presence
- B. presents
- C. present
- D. prescience
Correct Answer: B
Rationale: The correct answer is 'presents.' In this sentence, 'presents' is the correct verb form that agrees with the subject 'condition.' 'Presence' (choice A) is a noun, 'present' (choice C) is an adjective, and 'prescience' (choice D) means foresight, none of which fit the sentence structure. Therefore, 'presents' is the appropriate choice to maintain grammatical correctness. The sentence structure requires a verb to show the action of the condition, and 'presents' is the correct third-person singular form of the verb 'present' in this context.

Select the word or phrase in the sentence that is not used correctly. The salesman recommended that he keeps his receipt for at least a month.
- A. keeps
- B. at least
- C. for
- D. that
Correct Answer: A
Rationale: The correct answer is A: keeps. In the sentence, the verb "keeps" should be in the subjunctive form, which is "keep," to match the verb "recommended." The correct sentence should be "The salesman recommended that he keep his receipt for at least a month." The use of "keeps" is incorrect because it does not agree with the subjunctive mood required in this context.
Explanation:
- A (keeps): Incorrect, as it should be "keep" to match the verb "recommended."
- B (at least): Correctly used to indicate a minimum time period.
- C (for): Correctly used as a preposition indicating the duration.
- D (that): Correctly used to introduce the subordinate clause.
Select the word or phrase that makes this sentence grammatically correct: 'A synonym is a word ____ a meaning similar to another word.'
- A. Who have
- B. That have
- C. Who is having
- D. Having
Correct Answer: D
Rationale: In the given sentence, the correct phrase should be 'Having' as it correctly completes the sentence structure. 'A synonym is a word having a meaning similar to another word.' This choice maintains the correct subject-verb agreement and conveys the intended meaning of the sentence. 'Having' is the present participle form of the verb 'have,' which is used to show possession or relationship, making it the appropriate choice in this context.
Which of the following sentences is INCOMPLETE?
- A. We sat out the next dance.
- B. While the band played.
- C. The band played a nice slow song.
- D. Everyone enjoyed the dance.
Correct Answer: B
Rationale: An incomplete sentence lacks a subject, verb, or complete thought. In this case, choice B, 'While the band played,' is incomplete as it doesn't express a complete idea on its own and is a dependent clause. It requires additional information to form a complete sentence. The other options are complete sentences with subjects (e.g., 'We,' 'The band,' 'Everyone'), verbs (e.g., 'sat,' 'played,' 'enjoyed'), and complete thoughts, making them complete sentences that can stand alone.
Which sentence is grammatically correct?
- A. Heather owned eight dogs; unfortunately, her sister was allergic to them.
- B. We lost the game; consequently, we fell out of the top ten ranking.
- C. Moving to a big city can be exciting; therefore, do it when you are young.
- D. Feeding a child is important; however, too much food can risk obesity.
Correct Answer: B
Rationale: The correct answer is B because 'consequently' is correctly used after a semicolon to connect two independent clauses. In this case, the first clause 'We lost the game' and the second clause 'we fell out of the top ten ranking' are both complete sentences. The semicolon is used to join closely related ideas. Options A, C, and D misuse transitional words. Transitional words such as 'unfortunately,' 'therefore,' and 'however' require a semicolon or a period before them when used to connect independent clauses in a sentence. Therefore, option B is the only choice that demonstrates proper use of a semicolon with the transitional word 'consequently.'
What is the correct preposition to complete the sentence?
A tuberculin skin test should be read within 24 hours __________ administration.
- A. of
- B. since
- C. as
- D. from
Correct Answer: A
Rationale: The correct preposition to use in this context is 'of.' The sentence structure requires 'of' to indicate the specific time frame (24 hours) in relation to the action (administration). Therefore, the sentence should read: 'A tuberculin skin test should be read within 24 hrs of administration.' This preposition correctly links the time frame to the action being performed.
