1. What does Medial mean?
- A. Away from the midline
- B. Toward the midline
- C. At the side
- D. Below the body
Correct answer: B
Rationale: Medial means toward the midline of the body. In anatomical terms, 'medial' refers to positions closer to the midline of the body, which divides the body into left and right halves. Choice A is incorrect as it describes 'lateral,' which means away from the midline. Choice C is incorrect as it describes 'lateral' or 'side.' Choice D is incorrect as it describes 'inferior,' which means below or lower in position.
2. This medication works by inhibiting the action of a certain enzyme. What does inhibiting mean?
- A. Blocking
- B. Hindering
- C. Energizing
- D. Blocking improvement
Correct answer: B
Rationale: The correct answer is 'B: Hindering.' Inhibiting means to hinder or slow down a process. Choices A and D are similar and imply a complete stop of the process rather than just slowing it down. Choice C, 'Energizing,' is the opposite of inhibiting, as it means to provide energy or stimulate rather than hinder.
3. What does Consistency refer to?
- A. Color of a fluid
- B. Degree of viscosity, how thick or thin a fluid is
- C. Taste of a fluid
- D. Smell of a fluid
Correct answer: B
Rationale: Consistency refers to the degree of viscosity of a fluid, indicating how thick or thin it is. Viscosity is the resistance of a fluid to flow, and it determines its consistency. Choices A, color, C, taste, and D, smell, are not related to consistency. Color, taste, and smell are sensory attributes that do not define the physical property of consistency in fluids.
4. What does Gaping mean?
- A. Partially closed
- B. Wide open
- C. Narrow
- D. Sealed
Correct answer: B
Rationale: The correct answer is B, 'Wide open'. Gaping refers to something being wide open, not partially closed (choice A), narrow (choice C), or sealed (choice D). In the context of the question, 'Gaping' describes something that is open widely.
5. I will call you when I _____ back from visiting my sister.
- A. get
- B. will get
- C. return
- D. came
Correct answer: A
Rationale: The correct answer is 'get' because it appropriately indicates a future action in the sentence. In English, when 'when' is used in future time clauses, the following verb should be in the present simple tense to indicate a future event, making 'get' the correct choice. Choices B, C, and D are incorrect. 'Will get' is redundant after 'when' in this context, 'return' is not the appropriate tense for a future action, and 'came' is in the past tense, which is not suitable for a future event.
