What is the meaning of the word 'placebo' in the following sentence: 'Ten patients will receive the experimental drug while 10 take a placebo'?

  • A. Fallback
  • B. Substitute
  • C. Control
  • D. Curative
Correct Answer: C

Rationale: In the context of the sentence, the word 'placebo' refers to a substance or treatment that resembles a real medical treatment but has no therapeutic effect. It is used as a standard against which the effects of the experimental drug are compared. A placebo is typically included in a control group in medical research to evaluate the actual effects of the experimental drug. Therefore, in this scenario, the placebo serves as a control to gauge the effectiveness of the experimental drug, making choice C the correct answer. Choices A, B, and D are incorrect because a placebo is not a fallback, substitute, or curative treatment in this context.

If a lump under the skin is palpable, what is true?

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.

What is the best description of the verb emit?

  • A. To discharge
  • B. To exclude
  • C. To dismiss
  • D. To moderate
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.

'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.
