• a.The group of students are studying.
• b.The group of students is studying.✓
• c.The group of students were study.
• d.The group of student are studying.

The subject 'group' is a singular collective noun, so it takes the singular verb 'is.' The prepositional phrase 'of students' does not change the number of the subject.

Choose the sentence that is punctuated correctly.

• a.After the exam, we went to lunch.✓
• b.After the exam we, went to lunch.
• c.After the exam we went, to lunch.
• d.After, the exam we went to lunch.

An introductory phrase such as 'After the exam' should be followed by a comma before the main clause. The comma correctly separates the introductory element from the rest of the sentence.

Which word is spelled correctly?

• a.Recieve
• b.Definately
• c.Necessary✓
• d.Occurence

'Necessary' is spelled correctly. The others should be 'receive' (i before e except after c), 'definitely,' and 'occurrence.'

Choose the correct word to complete the sentence: "The students turned in ___ completed assignments."

• a.they're

Which sentence is written in the active voice?

• a.The medication was given by the nurse.
• b.The nurse gave the medication.✓
• c.The medication had been given.

In the active voice, the subject performs the action. 'The nurse gave the medication' has the subject (nurse) doing the action. The other sentences are passive.

Choose the correct plural form of the word 'child.'

'Child' has an irregular plural, 'children.' It does not follow the standard rule of adding -s or -es.

• a.The nurses station was busy.
• b.The nurse's is busy.
• c.The nurse's station was busy.✓

Identify the pronoun in the following sentence: "She completed the assignment early."

'She' is a personal pronoun that takes the place of a noun. 'Completed' is a verb, 'assignment' is a noun, and 'early' is an adverb.

• a.I have went to the clinic yesterday.
• b.I went to the clinic yesterday.✓

Choose the sentence with correct capitalization.

• b.We visited New york in July.
• c.we Visited New York in July.

Proper nouns (New York) and the first word of a sentence, along with months (July), must be capitalized. The last option capitalizes all of these correctly.

Which word is an adjective in the sentence: "The tired nurse rested quietly"?

• b.The test was hard, I passed it.

• a.Their going to the seminar.
• b.The book is over their.

• b.We need gloves masks and gowns.
• c.We need gloves, masks and, gowns.
• d.We need, gloves, masks, and gowns.

Items in a series are separated by commas, including the optional serial comma before 'and.' 'Gloves, masks, and gowns' is correctly punctuated.

Which sentence is grammatically correct?

• a.Him and I went to class.
• b.He and I went to class.✓
• c.Me and him went to class.
• d.Him and me went to class.

As the subject of the sentence, the pronouns must be subjective: 'He and I.' Testing each alone ('He went,' 'I went') confirms correctness, while 'him' and 'me' are objective forms.

What is the meaning of the suffix '-itis' as used in 'arthritis'?

• a.Study of

• a.I don't have no time.
• b.She can't hardly wait.
• c.We didn't see nobody.

Which sentence uses a semicolon correctly?

• a.The clinic was busy; many patients waited.✓
• b.The clinic was busy; and patients waited.
• c.The clinic; was busy.

Identify the adverb in the sentence: "The doctor spoke calmly to the patient."

• a.doctor
• b.calmly✓
• c.patient
• d.spoke

Which of the following words is a synonym for 'benign'?

'Benign' means not harmful or not cancerous. 'Harmless' is a synonym. 'Harmful' and 'deadly' are antonyms in a medical context.

Select the sentence with correct pronoun-antecedent agreement.

• a.Each student must bring their book.
• b.Everyone lost their way.
• c.Neither of the boys did their part.
• d.Each nurse must complete her charting.✓

The singular antecedent 'each nurse' agrees with the singular pronoun 'her.' The other sentences pair singular antecedents (each, everyone, neither) with the plural 'their.'

What type of sentence is the following: "Please close the door."

• a.Imperative✓
• b.Interrogative
• c.Exclamatory
• d.Declarative

An imperative sentence gives a command or request and often has an implied subject 'you.' 'Please close the door' is a polite command, making it imperative.

Which word correctly completes the sentence: "The patient responded well to the treatment; ___, the doctor was pleased."

• a.however

The two clauses show a cause-and-effect relationship: because the patient responded well, the doctor was pleased. 'Therefore' signals this result. 'However' would wrongly signal contrast.

Identify the correctly spelled medical term.

Which sentence correctly uses the comparative or superlative form?

• a.This is the most easiest test.
• b.She is more taller than him.
• c.He runs faster more than her.
