What does Debilitating mean?

Correct Answer: A

Rationale: The correct answer is A: 'Incapacitating.' Debilitating means causing incapacity or weakness, making choice A the most appropriate. Choices B, C, and D are incorrect because they represent the opposite of what debilitating means. Weakening (choice B), Empowering (choice C), and Strengthening (choice D) all convey a sense of increasing strength or ability, which is the opposite of the meaning of debilitating.

Correct Answer: B

Rationale: The correct answer is B: 'A sum total of many things.' Aggregate refers to the total or sum of different elements or components. Choice A, 'A part of the whole,' is incorrect as aggregate does not refer to just a part but the whole combined. Choice C, 'A small fraction,' is incorrect as aggregate denotes a larger amount, not a small fraction. Choice D, 'A gradual reduction,' is incorrect as aggregate does not imply reduction but rather accumulation or combination.

Correct Answer: B

Rationale: The correct answer is B: 'Come to an end.' Cease means to stop or come to an end. Choice A, 'Start,' is the opposite of what Cease means. Choice C, 'Pause,' implies a temporary stop, which is not the same as coming to an end. Choice D, 'Skip,' means to omit or bypass, which is different from the meaning of Cease.

Correct Answer: B

Rationale: The correct meaning of 'contingent' is dependent, indicating reliance on something else. Choice A, 'Certain,' is incorrect as it means clearly established or assured, which does not align with the meaning of 'contingent.' Choice C, 'Unrelated,' is also incorrect as it means not connected or associated with, which is a different concept. Choice D, 'Guaranteed,' is not synonymous with 'contingent' as it implies assurance or confirmation, not dependency.

Correct Answer: B

Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.
