What does 'Contract' mean?

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: Exposure refers to coming into contact with external elements. Choice A is incorrect as exposure does not imply protection but rather contact. Choice C, absorption, refers to the process of soaking up or taking in something. Choice D, isolation, means being separated or kept apart from others, which is not synonymous with exposure.

Correct Answer: B

Rationale: The correct answer is B: 'Produced within the body.' Endogenous refers to substances or processes that originate or are produced within an organism or system. Choices A, C, and D are incorrect. Choice A, 'Produced outside the body,' is the opposite of endogenous. Choice C, 'Taken from an external source,' describes exogenous rather than endogenous. Choice D, 'Linked to environmental factors,' is not a direct definition of endogenous.

Correct Answer: B

Rationale: The correct answer is B. Diameter is defined as the distance across the center of an object, typically a circle. Choice A is incorrect because width refers to the measurement of something from side to side, not necessarily through the center. Choice C is incorrect because height is a measurement from top to bottom, not across the center. Choice D is incorrect because the radius of a circle is the distance from the center to any point on the circle's circumference, not the distance across the center.
