Correct Answer: D

Rationale: The correct answer is 'D: Sunken.' Concave refers to a surface or shape that curves inward, while 'sunken' is the closest synonym, also indicating something that is depressed or hollowed inward. Choice 'B: Convex' is incorrect as it is the opposite of concave, representing a shape that bulges outward. Choices 'A: Sunburned' and 'C: Puffed out' do not relate to the concept of concave shapes.

Correct Answer: B

Rationale: The term 'anterior' in anatomy refers to the front part of the body. It is used to describe the position of structures relative to the front of the body. Therefore, the correct answer is 'Front' (choice B). Choices A, C, and D are incorrect because 'anterior' specifically pertains to the front, not the back, side, or top of the body.

Correct Answer: D

Rationale: In a medical setting, when a healthcare provider asks about a patient's 'condition,' they are typically inquiring about the patient's physical state or health status. This encompasses aspects such as vital signs, symptoms, diagnosis, treatment progress, and overall well-being. 'A place in society,' 'Ability to pay,' and 'Whereabouts' are unrelated to the patient's health status and are not typically what a healthcare provider would ask about in this context. Therefore, the correct answer is 'Physical state,' as it aligns best with the context of healthcare and patient care.

Correct Answer: C

Rationale: The correct choice is C. Cloth because in the sentence, the new mother expressed a preference for using cloth diapers over disposables. 'Cloth' refers to a type of diaper material, and it makes sense in the context of the sentence. Choice A, 'Close,' is incorrect as it does not relate to the type of diapers being discussed. Choice B, 'Clothing,' is incorrect as it refers to garments worn on the body, not diapers. Choice D, 'Clothes,' is also incorrect as it is used for general garments, not specific to diapers.

Correct Answer: B

Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.
