Correct Answer: B

Rationale: Euthanasia, which involves deliberately ending a person's life to relieve suffering, is a controversial and illegal practice in many countries. Healthcare professionals should not be involved in performing euthanasia as it goes against medical ethics and principles of preserving life and providing care. Assistance in hastening death is not within the scope of healthcare professionals' responsibilities. Assessments, such as physical examinations or patient evaluations, are crucial for diagnosing and treating patients. Palliative care focuses on improving the quality of life for individuals with serious illnesses and should be provided by healthcare professionals. However, euthanasia is not an acceptable practice for healthcare professionals due to ethical considerations and legal restrictions.

Correct Answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious is an adjective that describes something that is extremely harmful or destructive. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Helpful,' is a positive term and does not align with the meaning of pernicious. Choice D, 'Harmful,' is a similar term to pernicious but lacks the emphasis on the severe and damaging nature of the word.

Correct Answer: A

Rationale: The word "ubiquitous" means present, appearing, or found everywhere. Another word that closely relates to this meaning is "widespread," which also refers to something that is prevalent or found in many places. The other choices, such as "last demand," "uncertainty," and "finally reckoned," do not accurately represent the synonym for "ubiquitous."

Correct Answer: B

Rationale: The correct sentence structure is 'The cat is sleeping on the mat.' This is a complete and grammatically correct sentence following a standard subject-verb-object structure. 'The cat' is the subject, 'is sleeping' is the verb, and 'on the mat' is the prepositional phrase describing where the action is taking place. Choices A, C, and D are incorrect. Option A is a sentence fragment lacking a verb; option C is a dependent clause lacking a main clause, and option D has a subject-verb inversion making it awkward and incorrect.
