What does 'External' refer to?

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 definition of dilute is to make a liquid less concentrated. When a substance is diluted, it means it has been mixed with another substance to reduce its strength or concentration. Option A, 'To concentrate,' is the opposite of dilute. Option C, 'To solidify,' means to make or become hard or solid, which is unrelated to diluting a liquid. Option D, 'To evaporate,' means to change from a liquid to a vapor, also unrelated to diluting a liquid. Therefore, the correct answer is B.

Correct Answer: B

Rationale: The correct definition of 'depress' is to press downward. This term is commonly used to describe pushing something downward or making something lower in position or level. Choice A, 'To push forward,' is incorrect as 'depress' does not involve moving something forward. Choice C, 'To remove,' is incorrect as 'depress' does not entail taking something away. Choice D, 'To elevate,' is incorrect as it is the opposite of what 'depress' means.

Correct Answer: B

Rationale: The term 'inflamed' means being red, swollen, and often tender. It is a common response of the body to injury or infection, involving increased blood flow and immune cell activity. Choice A is incorrect because 'inflamed' does not describe a state of being healthy and normal. Choice C is incorrect as it only mentions discoloration without the characteristic swelling. Choice D is incorrect as 'inflamed' does not imply being hard and stiff.

Correct Answer: B

Rationale: Internal means located within the body. When something is described as internal, it refers to being inside the body or contained within the boundaries of an organism. Choices A, C, and D are incorrect as they describe locations that are either near the surface, outside, or far from the body, respectively, which are not the meanings of 'internal.'
