Correct Answer: B

Rationale: The correct answer is B. 'Apology' transforms into 'apologize' when the suffix is added, changing the word from a noun to a verb. In this case, the suffix '-ize' is added to the noun 'apology' to form the verb 'apologize.' Choices A, C, and D do not involve a transformation from a noun to a verb when a suffix is added. 'Biology' and 'biologist' are related but not in a noun-to-verb transformation. 'Happy' and 'happily' involve an adjective-to-adverb transformation. 'Mineral' and 'mineralogy' are related terms in the same field but do not show a noun-to-verb change.

Correct Answer: C

Rationale: The correct answer is C: 'I can't bear to see this.' The words 'bear' and 'bare' are homonyms, as they sound the same but have different meanings. Choice A does not contain a homonym; it correctly uses 'bear' in the context of enduring pain. Choice B uses 'bear' as a noun referring to the animal, not a homonym. Choice D uses 'bears' as a verb, not a homonym.

Correct Answer: A

Rationale: Choice A, 'theirs,' is a possessive pronoun indicating ownership. In this sentence, 'theirs' shows possession by referring to something belonging to the patient. Choices B, C, and D do not contain possessive pronouns. Choice B uses the possessive form 'hospital's,' but it is a possessive noun, not a pronoun. Choice C uses 'personal items,' where 'personal' is an adjective and 'items' is a noun. Choice D does not include any possessive pronouns or possessive nouns.

Correct Answer: D

Rationale: In this context, 'entrance' is used as a verb meaning to enchant or captivate. The glittering lights were intended to captivate or charm the guests as they arrived, not to physically enter them (choice A), provide a passage (choice B), or present an opportunity (choice C). Therefore, the correct answer is 'enchant.'

Correct Answer: B

Rationale: The correct answer is 'B - Informal.' The passage provides practical advice in a casual and conversational tone, making it suitable for informal writing. Choices A, C, and D are incorrect. 'Formal' writing would be more structured and sophisticated, often used in professional or academic settings. 'Colloquial' writing involves informal, everyday language specific to a particular region or group, which is not the case here. 'Slang' is informal language that is more casual and may not be appropriate for professional advice like in the given passage.
