Identify the correct sentence structure.
- A. The cat sleeping on the mat
- B. The cat is sleeping on the mat
- C. The mat that the cat is sleeping on
- D. Sleeping on the mat is the cat
Correct Answer: B
Rationale: The correct sentence structure is 'The cat is sleeping on the mat.' This is a complete and grammatically correct sentence following a standard subject-verb-object structure. 'The cat' is the subject, 'is sleeping' is the verb, and 'on the mat' is the prepositional phrase describing where the action is taking place. Choices A, C, and D are incorrect. Option A is a sentence fragment lacking a verb; option C is a dependent clause lacking a main clause, and option D has a subject-verb inversion making it awkward and incorrect.
What does Latent mean?
- A. Easily seen
- B. Present but not active or visible
- C. Quick to react
- D. Actively growing
Correct Answer: B

Choice A, 'Easily seen,' is incorrect as latent implies the opposite - not easily seen. Choice C, 'Quick to react,' is incorrect as latent does not imply a quick reaction but rather a hidden or dormant state. Choice D, 'Actively growing,' is incorrect as latent suggests the opposite - not actively growing but rather inactive or concealed.
Which word is used incorrectly? 'Which procedure for giving injections was explained thoroughly to the student nurses.'
- A. procedure
- B. was
- C. explained
- D. thoroughly
Correct Answer: B
Rationale: The correct answer is 'B - was.' In the original question, 'were' is incorrectly used as the verb, which should be singular to match the singular subject 'procedure.' The subject 'procedure' requires the singular form 'was' instead of the plural form 'were.' Choices A, C, and D are all used correctly in the sentence.
