Correct Answer: D

Rationale: Flux is a term used to describe a discharge, which refers to the action of discharging or releasing something. In medical contexts, flux can specifically refer to a discharge of bodily fluids or matter. 'Flowing' (Choice A) is not a synonym of flux; it implies continuous movement rather than discharge. 'Restriction' (Choice B) and 'Absorption' (Choice C) are unrelated to the concept of flux and do not convey the same meaning.

Correct Answer: B

Rationale: The term 'External' refers to something that is located outside the body. In this context, it specifically denotes a position or location that is beyond the confines of the body's boundaries. Choice A is incorrect as 'External' means outside, not inside. Choice C is incorrect as it confuses the internal exposure with external positioning. Choice D is incorrect as 'External' does not necessarily mean near the skin, but rather outside the body.

Correct Answer: B

Rationale: The correct answer is B: The mechanical and chemical breakdown of food. Digestion involves breaking down food mechanically and chemically into smaller components for absorption by the body. This process occurs in the digestive system, preparing nutrients for absorption in the intestines. Choices A, C, and D are incorrect because digestion is not solely about the production of enzymes, absorption of nutrients in the blood, or movement of enzymes; it primarily involves breaking down food for nutrient absorption.

Correct Answer: C

Rationale: Another word for UNDER OBSERVATION is surveillance. Surveillance refers to the close observation of a person, group, or place, especially in a secret or discreet manner. It involves monitoring and watching over someone or something closely for a specific purpose. Therefore, the word 'surveillance' is the most suitable synonym for under observation in this context. Choice A, 'Cognition,' refers to the mental process of acquiring knowledge and understanding through thoughts, experience, and the senses; it is not synonymous with under observation. Choice B, 'Isolation,' means the process or fact of isolating or being isolated, which does not convey the idea of close monitoring. Choice D, 'Assessment,' involves evaluating or judging the nature, ability, or quality of something, which is different from the act of observing closely.

Correct Answer: B

Rationale: In this sentence, 'effect' is the correct term to use as it refers to the outcome or consequence of the weather, which was that everyone got wet. 'Effect' is a noun that indicates the result of a particular action or situation. Choice A 'result' is incorrect because it refers to the outcome of an action, not the outcome of weather. Choice C 'affect' is incorrect as it is used as a verb to show influence or make a difference. Choice D 'impact' is incorrect because it refers to a strong influence or effect.
