Correct Answer: C

Rationale: A "nostrum" is a term used to describe a questionable or untested remedy or medication that claims to cure ailments. In this context, as a remedy is suggested to cure certain ailments, "nostrum" fits best in providing an alternative word that aligns with the situation. The other choices are not synonyms for a remedy that cures ailments. 'Inoculation' refers to the introduction of a vaccine, 'indicator' is something that provides information or signals, and 'serum' is a component of blood or a medication, none of which directly align with the concept of a remedy curing ailments.

Correct Answer: D

Rationale: In this sentence, the word 'tumult' is used to describe a state of confusion, disorder, and chaos in the emergency room. 'Commotion' is the closest synonym to this meaning, making it the correct choice from the list provided. Choice A, 'Siren,' does not capture the meaning of chaos and disorder. Choice B, 'Distress,' refers more to a state of extreme anxiety or suffering rather than the commotion described. Choice C, 'Suffering,' is not the best fit as the word 'tumult' in this context does not specifically imply suffering, but rather a noisy and chaotic situation.

Correct Answer: A

Rationale: A symptom that is transitory is short-lived. It appears temporarily and does not persist for an extended period of time. This term indicates that the symptom is not permanent or continuous but rather temporary or fleeting.\nChoice B, damaging, is incorrect as transitory refers to the duration of the symptom, not its impact. Choice C, fluctuating, is incorrect as it implies the symptom varies in intensity, not necessarily in duration. Choice D, degenerating, is incorrect as it suggests a worsening or deteriorating condition, which is not implied by transitory.

Correct Answer: B

Rationale: Superfluous means unnecessary or more than what is needed. It refers to something that is excessive or redundant. Choice B, "Excessive," is the correct synonym for superfluous. Choices A, C, and D are incorrect. "Maximum" (Choice A) means the greatest possible amount, "Insipid" (Choice C) means lacking flavor or interest, and "Soggy" (Choice D) means soaked with liquid or water.

Correct Answer: C

Rationale: Bifurcate means to divide into two forks or branches. It comes from the Latin word "bi" meaning two and "furca" meaning fork. So, when something bifurcates, it splits into two separate paths or divisions. Choice A, "Fold twice," is incorrect as bifurcate doesn't involve folding. Choice B, "Flower biannually," is unrelated to the meaning of bifurcate. Choice D, "Pierce two openings," is also incorrect as it does not capture the true essence of bifurcate, which is about dividing into two forks or branches.
