Correct Answer: D

Rationale: When a symptom is exacerbated, it means that it is made worse or intensified beyond its usual level of severity. This can lead to increased discomfort, pain, or other negative effects associated with that particular symptom. Choice A is incorrect because exacerbation does not imply that the symptom is not dangerous. Choice B is incorrect as exacerbation does not necessarily mean disfiguring. Choice C is incorrect as exacerbation does not always specifically refer to pain, but to any worsening of a symptom.

Correct Answer: A

Rationale: The correct answer is A, 'Insignificant.' Paltry and insignificant are synonymous terms that denote something as unimportant, trivial, or of little value. Choice B, 'Punitive,' means inflicting or intended as punishment, which is unrelated to the meaning of paltry. Choice C, 'Prolonged,' means continuing for a long time, which is not a synonym for paltry. Choice D, 'Economical,' means giving good value or service in relation to the amount of money, which is not synonymous with paltry.

Correct Answer: D

Rationale: To cauterize a wound is to use heat or a chemical to burn the wound in order to stop bleeding and prevent infection. This process helps seal off blood vessels and close the wound by burning the affected tissue. Choice A, 'soothe it,' is incorrect because cauterization involves burning the wound, which is a controlled way of treating it, not soothing it. Choice B, 'cover it,' is incorrect as cauterization involves a more aggressive approach than just covering the wound. Choice C, 'stitch it,' is incorrect as it refers to using sutures to close a wound, which is different from cauterization that involves burning the wound to seal it.

Correct Answer: B

Rationale: The correct answer is B: A type of lipoprotein. LDL stands for Low-density lipoprotein, which is a type of lipoprotein that carries cholesterol through the bloodstream. LDL is often referred to as 'bad' cholesterol because high levels of LDL can lead to plaque buildup in the arteries, increasing the risk of heart disease and stroke. Choices A, C, and D are incorrect as they do not accurately describe the abbreviation LDL.

Correct Answer: A

Rationale: Qualms refer to feelings of doubt, hesitation, or uneasiness about something. They are typically used to describe a person's reservations or concerns about a decision or action. This aligns with the meaning of 'misgivings,' making it the correct choice in this context. Choices B, C, and D are incorrect. 'Habits' refer to regular tendencies or practices, 'Serenity' refers to a state of calm or peace, and 'Dispatches' refer to sending off to a destination or taking care of a task promptly, none of which capture the meaning of 'qualms.'
