Correct Answer: B

Rationale: The correct answer is B: Less severe. When a treatment mitigates symptoms, it means the treatment is reducing the intensity or severity of the symptoms. This implies that the symptoms are becoming milder or less intense, hence less severe. The other choices are incorrect because if the symptoms were to get worse (A), remain unchanged (C), or become unbearable (D), it would indicate that the treatment is not effective in alleviating the symptoms.

Correct Answer: B

Rationale: The correct answer is B: Straightforward. "Guileless" means sincere, honest, without deceit. In this context, the sentence implies that the person's lack of guile makes her easily understood and trustworthy. Rationale: 1. "Guileless" is defined as lacking deception or cunning. 2. The phrase "her most noticeable qualities" indicates a positive trait. 3. "Straightforward" is synonymous with honest and sincere, aligning with the meaning of guileless. Other choices are incorrect: A: Deceptive - The opposite of guileless. C: Complex - Does not relate to the absence of deceit. D: Untrustworthy - Opposite in meaning to guileless.

Correct Answer: B

Rationale: The correct answer is B: Changing rapidly and often. Labile means easily altered, unstable, or constantly changing. This term is commonly used in psychology and medicine to describe emotions or conditions that fluctuate frequently. Choice A (Stable) is incorrect because labile implies the opposite of stability. Choice C (Unchanging) and choice D (Rarely changing) are also incorrect as they do not align with the definition of labile, which specifically denotes frequent changes.

Correct Answer: B

Rationale: The correct answer is B: Disregard. The word "contravene" means to violate or disobey. In this context, the interns did not follow the doctor's orders, which implies they disregarded them. Choice A (Follow) is incorrect because the interns did not adhere to the orders. Choice C (Exceed) is incorrect as it suggests going beyond the orders, not disobeying them. Choice D (Respect) is incorrect as it implies the interns obeyed the orders, which is not the case. Therefore, the best fit is B as the interns went against the doctor's instructions.

Correct Answer: D

Rationale: The correct answer is D: Ruminate. To ruminate means to think deeply about something before making a decision. This word specifically implies a process of careful consideration and reflection. Choice A, imply, means to suggest indirectly and does not convey the idea of thoughtful consideration. Choice B, transgress, means to violate a rule or boundary, which is unrelated to thinking before making a decision. Choice C, allay, means to alleviate or calm, which is not related to the act of thinking before deciding. Therefore, only choice D, ruminate, aligns with the concept of contemplating before making a decision.
