Correct Answer: A

Rationale: The correct answer is A: 'Plethora.' In the context provided, 'cornucopia' is used metaphorically to signify an abundance or a large variety of stimulating questions and conversation. 'Plethora' is a synonym for 'cornucopia' and means an excessive amount or abundance. Choices B, C, and D are incorrect. 'Ostracism' means exclusion or rejection, 'Laborious' means requiring a lot of effort, and 'Pensive' means engaged in deep thought.

Correct Answer: A

Rationale: The correct answer is 'Refrain.' 'Refrain' is synonymous with 'abstain,' meaning to hold oneself back. The other choices are incorrect. 'Indulge' means to allow oneself to enjoy the pleasure of something, 'Adhere' means to stick to or follow, and 'Eliminate' means to completely remove or get rid of.

Correct Answer: A

Rationale: The correct answer is A, 'Raised.' In this context, 'elevated' means to be lifted or raised up. The doctor's instruction implies keeping the patient's head in an upward position. Choices B, C, and D are incorrect. 'Turned' suggests a change in direction, 'still' means without movement, and 'thrown back' implies a forceful backward motion, none of which capture the meaning of 'elevated' in this scenario.

Correct Answer: A

Rationale: In this context, 'insidious' means progressing slowly but having harmful effects. This matches the meaning of 'gradual,' making it the correct answer. 'Momentous' means significant or important, which is not the meaning conveyed by 'insidious.' 'Sudden' means abrupt or unexpected, opposite to the slow progression indicated by 'insidious.' 'Innocuous' means harmless, which is the opposite of the harmful effects associated with an insidious disease.

Correct Answer: A

Rationale: The correct answer is 'Hyperbole.' Hyperbole refers to exaggerated statements or claims not meant to be taken literally. In this context, the team captain's claim about the number of goals scored is an exaggerated statement, making 'Hyperbole' the most suitable term. 'Validity' refers to the quality of being logically or factually sound and does not fit the scenario described. 'Eulogy' is a speech or piece of writing that praises someone or something, typically someone who has died, and is unrelated to the question. 'Simile' is a figure of speech involving the comparison of one thing with another thing of a different kind, used to make a description more emphatic or vivid, which is not the case in the scenario provided.
