Correct Answer: B

Rationale: The correct answer is 'B: Continuous.' 'Ongoing' is used to describe something that is currently happening or continuing without interruption. Choices A, C, and D are incorrect because 'Ended,' 'Delayed,' and 'Occasional' do not reflect the continuous nature associated with 'Ongoing.'

Correct Answer: B

Rationale: The correct answer is B: 'Guarded.' Circumspect means to be cautious or guarded. In this context, being circumspect with patient records implies being careful and cautious in handling them, maintaining confidentiality and privacy. Choices A, C, and D are incorrect because circumspect does not mean acting carelessly, reckless, or neglecting; instead, it suggests being watchful and discreet.

Correct Answer: B

Rationale: The correct answer is B: 'Swift.' PRECIPITOUS means something that is steep or sheer, often used to describe a very rapid or sudden change. This word does not relate to something gradual (choice A), slow (choice C), or delayed (choice D). Therefore, 'Swift' is the best definition for PRECIPITOUS.

Correct Answer: A

Rationale: The correct answer is A: 'This door will remain unlocked when the office is occupied.' This choice provides a clear and grammatically correct revision of the original sentence. Choice B is incorrect due to the missing 'will' before 'remain' and 'the' before 'office.' Choice C is incorrect as it does not include 'the office,' making it less specific. Choice D is incorrect as it uses 'while' instead of 'when,' changing the intended meaning.

Correct Answer: C

Rationale: A flexible tube would be appropriate for navigating through a curved pipe as it can bend and maneuver easily within the pipe's shape. This flexibility allows the plumber to access and address any blockages or issues efficiently. Solid and rigid tubes would be challenging to use in a curved pipe due to their lack of flexibility, making navigation difficult. Perforated tubes, with holes, are not typically used for this purpose and are more suited for specific applications like drainage systems.
