Select the word or phrase that makes the following sentence grammatically correct: 'Why did we ____ try so hard?'
- A. has to
- B. haven't
- C. had to
- D. have to
Correct Answer: D
Rationale: 'Have to' is the correct choice as it fits the sentence structure. The sentence is in the past tense ('did we') and requires the infinitive form 'have to' to express the idea of necessity or obligation in the past. 'Has to' (Choice A) is incorrect as it is present tense, 'haven't' (Choice B) is a negative form and does not make sense in this context, and 'had to' (Choice C) would imply a past obligation that has already been fulfilled, which is not the intended meaning here.

In the following sentence, which word or phrase is the subject: 'The nurses went to the conference room.'
- A. conference
- B. went to
- C. room
- D. nurses
Correct Answer: D
Rationale: In the sentence, 'The nurses went to the conference room,' 'nurses' is the subject. The subject of a sentence is typically the noun or pronoun that carries out the action or is described in the sentence. In this case, 'nurses' is the noun performing the action of going to the conference room. Choices A, B, and C are not the subject. 'Conference' and 'room' are objects of the prepositions 'to' and 'the,' while 'went to' is the verb phrase indicating the action performed by the subject.
Select the correct word for the blank in the following sentence: 'Sharon felt ____ about how her speech had gone.'
- A. well
- B. good
- C. finely
- D. happily
Correct Answer: B
Rationale: In this context, 'good' is the appropriate word to describe Sharon's feelings about her speech. 'Good' is used to express a positive sentiment which fits well with how one would feel about the outcome of a speech. 'Well' typically refers to the state of health or being done in a good way, not emotions. 'Finely' refers to something done very carefully or skillfully, not an emotional state. 'Happily' denotes a feeling of joy or pleasure, which may not be the most suitable term for describing her feelings about the speech outcome.
Select the word or phrase that makes this sentence grammatically correct: 'Sometimes, the condition ____ with an unusual symptom-vertigo.'
- A. presence
- B. presents
- C. present
- D. prescience
Correct Answer: B
Rationale: 'Presents' is the correct choice here. The sentence requires a verb that indicates the condition appearing with a symptom. In medical terminology, when a condition 'presents' with a symptom, it means that the symptom is a noticeable feature or indication of the condition. Therefore, 'presents' is the appropriate verb to describe how the condition manifests itself with vertigo. The other options do not fit the grammatical structure of the sentence.
Select the word or phrase that makes this sentence grammatically correct: 'The development committee ____ a bargain with the city planners.'
- A. striked
- B. stroke
- C. struck
- D. strike
Correct Answer: C
Rationale: The correct answer is 'C: struck.' In this context, the correct verb form should be 'struck' as it is the past tense form of 'strike.' Therefore, the correct sentence should read: 'The development committee struck a bargain with the city planners.'
Choice A, 'striked,' is incorrect as 'strike' is an irregular verb, and the past tense is 'struck' rather than 'striked.' Choice B, 'stroke,' is incorrect as it is not the correct past tense form of 'strike' in this context. Choice D, 'strike,' is incorrect as it is the base form of the verb and does not fit the sentence structure requiring a past tense verb.
Select the phrase that makes the following sentence grammatically correct: 'Working ____ the mission of the entire committee.'
- A. to peace is
- B. toward peace was
- C. to peace was
- D. toward peace am
Correct Answer: B
Rationale: The correct phrase to complete the sentence is 'toward peace was.' In this context, 'toward peace' is the appropriate prepositional phrase to indicate the direction or goal of the work being done. Additionally, the verb tense should be in the past tense ('was') to match the structure of the sentence. Choice A and C are incorrect because 'to peace' does not convey the intended sense of direction or goal. Choice D is incorrect as 'am' is present tense, which does not agree with the past tense structure of the sentence.
