The plumber used a flexible tube to open up the curved pipe.

Correct Answer: C

Rationale: The term 'flexible' accurately describes the type of tube used in the given context. A 'solid' tube would not have been suitable for navigating a curved pipe as it is not pliable. 'Rigid' implies stiffness and inflexibility, making it unsuitable for the task. 'Perforated' means pierced with holes, which is unrelated to the plumber's task of opening up a curved pipe.

Correct Answer: B

Rationale: The correct answer is B because 'anticipatory grieving' refers to the process of grieving in anticipation of a significant loss or change. In this case, a patient who is expecting a leg amputation tomorrow is experiencing anticipatory grieving as they are grieving the loss of a limb before it actually occurs. Choices A, C, and D do not involve an impending significant loss or change that would lead to anticipatory grieving.

Correct Answer: A

Rationale: The correct answer is 'A: Breathe.' When a child has a stuffy nose, the difficulty they experience is related to the action of breathing. 'Breathing' (choice B) is a gerund and doesn't fit the context of the question. 'Breath' (choice C) is a noun, not the correct verb form. 'Breadth' (choice D) refers to the extent or width of something and is unrelated to the child's difficulty due to a stuffy nose.

Correct Answer: B

Rationale: The correct answer is B, 'Convulsion.' A paroxysm and a convulsion both refer to sudden, involuntary spasms. This makes 'Convulsion' the most suitable synonym. 'Symptom' (Choice A) refers to an indication of a condition but not a spasm. 'Efficacy' (Choice C) refers to the ability to produce a desired or intended result, unrelated to spasms. 'Embolism' (Choice D) refers to an obstruction in a blood vessel, not a sudden spasm.
