Correct Answer: B

Rationale: In medicine, when a microorganism or pathogen is described as resistant, it means that it is not affected by the drug or treatment being used against it. Resistance can develop due to various factors, making the pathogen no longer susceptible to the effects of the treatment. Therefore, the correct answer is 'unaffected by.' The other choices are incorrect: 'unwilling' and 'opposed to' do not accurately describe the concept of resistance in medicine, and 'accepting of' is the opposite of what resistance represents in this context.

Correct Answer: A

Rationale: The best description of the verb emit is 'to discharge.' Emit means to produce and release something such as a sound, odor, or substance. Discharge is synonymous with emit in this context as it conveys the idea of releasing or sending out something, which aligns with the meaning of emit. Choices B, C, and D are incorrect. 'To exclude' means to deny access or prevent from entering, which is not the same as emit. 'To dismiss' means to remove from consideration or to let go, which is different from emitting. 'To moderate' means to make or become less extreme, intense, or severe, which is not the same as emitting or releasing something.

Correct Answer: C

Rationale: Hypothetical is best defined as being assumed because it describes something that is based on a theory or assumption rather than solid proof or certainty. Hypothetical situations are used to explore different possibilities or outcomes without being confirmed as true or existing. Choice A, 'rigorous,' does not accurately define hypothetical, as it refers to something that is extremely thorough, accurate, or carefully done. Choice B, 'short-term,' is unrelated to the definition of hypothetical. Choice D, 'convinced,' does not capture the essence of hypothetical, which is more about assumptions and possibilities rather than being convinced of something.

Correct Answer: B

Rationale: The correct answer is B: Caesarean. The C in C-section stands for 'Caesarean' after Julius Caesar, who was rumored to have been born via this surgical procedure. The term 'Caesarean' is derived from the Latin word 'caesus,' meaning cut or incised. Choice A, Carthusian, is incorrect as it does not relate to childbirth. Choice C, Cartesian, is unrelated to the medical procedure. Choice D, Caedmon, is also irrelevant in the context of C-sections.

Correct Answer: D

Rationale: If a lump under the skin is palpable, it means that it can be felt or touched. Palpable lumps can be detected by touch, which can lead to further evaluation or examination by a healthcare professional to determine the cause and appropriate treatment. The correct answer is 'D' because when a lump is palpable, it means it can be physically felt, indicating its presence under the skin. Choices A, B, and C are incorrect because the palpability of a lump does not automatically indicate malignancy, bursting, or warmth.
