1. What is the meaning of 'belligerent'?
- A. retired
- B. sardonic
- C. pugnacious
- D. acclimated
Correct answer: C
Rationale: The correct answer is C, 'pugnacious.' 'Belligerent' means aggressive or combative, which aligns with the definition of 'pugnacious.' Choice A, 'retired,' is incorrect as it does not relate to the aggressive or combative nature of 'belligerent.' Choice B, 'sardonic,' means grimly mocking or cynical, which is not synonymous with 'belligerent.' Choice D, 'acclimated,' means to become accustomed to a new climate or environment, which is unrelated to the meaning of 'belligerent.'
2. What are the soft spots on the head of a newborn called?
- A. Fistula
- B. Fontanel
- C. Follicle
- D. Fissure
Correct answer: B
Rationale: The correct answer is 'Fontanel.' Fontanels are the soft spots on a newborn's head where the skull bones have not yet fused together, allowing for some flexibility during birth and rapid brain growth in early infancy. 'Fistula' is a medical term for an abnormal connection between two body parts. 'Follicle' refers to a small cavity in the skin from which hair grows. 'Fissure' is a narrow opening or crack, not related to the soft spots on a newborn's head.
3. Hypothetical is best defined as being ___________.
- A. rigorous
- B. short-term
- C. assumed
- D. convinced
Correct answer: C
Rationale: Hypothetical is best defined as being assumed because it describes something that is based on a theory or assumption rather than solid proof or certainty. Hypothetical situations are used to explore different possibilities or outcomes without being confirmed as true or existing. Choice A, 'rigorous,' does not accurately define hypothetical, as it refers to something that is extremely thorough, accurate, or carefully done. Choice B, 'short-term,' is unrelated to the definition of hypothetical. Choice D, 'convinced,' does not capture the essence of hypothetical, which is more about assumptions and possibilities rather than being convinced of something.
4. Choose the meaning of the word 'adverse' in the following sentence: 'Occasionally, this medicine causes an adverse reaction.'
- A. Unfavorable
- B. Contrary
- C. Noticeable
- D. Startling
Correct answer: A
Rationale: The word 'adverse' in the sentence is most closely aligned with the meaning of 'unfavorable.' An adverse reaction to a medicine signifies a negative or harmful response, which supports the definition of unfavorable. Choice B, 'Contrary,' does not accurately capture the negative connotation associated with 'adverse.' Choice C, 'Noticeable,' does not reflect the meaning in the context provided. Choice D, 'Startling,' suggests a more sudden or surprising nature, which is not the primary meaning of 'adverse' in this context.
5. What is the correct pronoun to complete the sentence?
- A. Her
- B. Hers
- C. Best
- D. More greatest
Correct answer: A
Rationale: The word 'her' is the correct choice because it serves as the object of the preposition 'at.' In this sentence, 'looked at' requires an object pronoun, making 'her' the appropriate choice. Option B, 'Hers,' indicates possession, which is not needed in this context. Options C and D are not pronouns and do not fit grammatically in the sentence.
