Correct Answer: B

Rationale: The correct answer is B: 'Swift.' Precipitous is used to describe something that is steep, sheer, or done suddenly and without careful consideration. For example, a precipitous drop in the stock market. 'Slow' (Choice A), 'Gradual' (Choice C), and 'Delayed' (Choice D) do not align with the meaning of precipitous and are therefore incorrect.

Correct Answer: B

Rationale: The correct answer is B: 'To draw together.' Contract means to reduce in size or draw together. Choices A, C, and D are incorrect because they suggest actions opposite to what contracting means. A: 'To expand,' C: 'To elongate,' and D: 'To dissolve' all indicate actions that involve increasing in size or breaking apart, which are the opposite of what contracting means.

Correct Answer: B

Rationale: The correct answer is B: 'Conspiracy.' Collusion refers to a secret agreement or conspiracy, often for deceitful or illegal purposes. Choice A, 'Cooperation,' is incorrect as collusion implies a deceptive or dishonest agreement, not a genuine cooperation. Choice C, 'Separation,' is incorrect as it denotes the opposite of collusion, which involves working together secretly. Choice D, 'Rejection,' is unrelated to collusion, which involves secret cooperation for deceptive purposes.

Correct Answer: A

Rationale: Concave means rounded inward. When something is concave, it curves inwards like the interior of a bowl. Choice B, 'Rounded outward,' is incorrect as this describes a convex shape, not concave. Choice C, 'Straight,' is incorrect as concave refers to a curved shape, not a straight one. Choice D, 'Flat,' is also incorrect as it does not describe the inward curve characteristic of concave shapes.

Correct Answer: A

Rationale: The correct answer is A: Dejected. After becoming INVALID, one is likely to feel dejected, meaning sad and disheartened due to feeling invalidated or rejected. It is a common emotional response to a situation where one's worth or validity is questioned or denied. Option B, shamefully fearful, does not directly relate to the emotional state associated with being an invalid. Option C, injured, does not capture the emotional aspect but rather focuses on the physical condition. Option D, symbiotic, refers to a mutually beneficial relationship between two different organisms and is not relevant to the emotional state of an individual after becoming an invalid.
