Correct Answer: D

Rationale: The correct answer is D, 'Emotional behavior.' Histrionics refer to exaggerated or dramatic emotional behavior, often characterized by theatricality or over-the-top expressions of emotions. It is more related to dramatic and exaggerated emotional displays rather than accomplishments, daring acts, or examinations. Choices A, B, and C are incorrect because histrionics specifically pertain to emotional behavior and not achievements, daring actions, or assessments.

Correct Answer: D

Rationale: Unruffled means calm and not agitated. The word 'composed' also means calm and collected, making it the correct synonym in this context. 'Concerned' (choice A) means worried or anxious, 'wholesome' (choice B) means promoting health and well-being, and 'tedious' (choice C) means boring or monotonous, making them all incorrect choices.

Correct Answer: A

Rationale: The correct answer is A: 'relieve it.' To alleviate a symptom means to reduce or improve it, thus providing relief or easing of the discomfort or issue being experienced. Choice B, 'diagnose it,' is incorrect as diagnosing a symptom involves identifying or determining its cause, not relieving it. Choice C, 'suffer from it,' is incorrect as it refers to experiencing the symptom, not alleviating it. Choice D, 'manage it,' is incorrect as managing a symptom involves controlling or handling it, not necessarily reducing or relieving it.

Correct Answer: A

Rationale: The word 'derivative' in this sentence means that the professor's lecture was not original, but instead heavily based on or closely imitating something else. Therefore, the correct meaning is 'unoriginal.' Choices B, C, and D are incorrect. 'Monotonous' means lacking in variety and boringly repetitive, 'condescending' means showing a superior attitude, and 'long-winded' means using more words than necessary.

Correct Answer: D

Rationale: The word 'contravene' in this sentence means to go against or disobey. Therefore, the correct meaning is closest to 'disregard.' The interns did not follow or comply with the doctor's orders, indicating that they contravened them. 'Comply with' (Choice A) is the opposite of 'contravene,' 'misjudge' (Choice B) and 'comprehend' (Choice C) do not accurately reflect the meaning of 'contravene' in this context.
