Correct Answer: A

Rationale: The correct answer is A: 'Occurrence.' Incidence refers to the frequency or occurrence of something happening. Choice B, 'Disappearance,' is incorrect as it means vanishing or ceasing to exist. Choice C, 'Growth,' is incorrect as it refers to an increase in size, number, or development. Choice D, 'Repetition,' is incorrect as it means the action of repeating something that has already been said or written.

Correct Answer: D

Rationale: The word 'throughout' means in every part of a place or thing. In this context, if the sound of the bells could be heard in the entire community, then it implies that the sound could be heard throughout the community, making 'Throughout' the most appropriate answer. Choice A 'Thorough' means complete or absolute, which does not fit the context of the sentence. Choice B 'Thought' is a past tense form of the verb 'think,' which is grammatically incorrect in this sentence. Choice C 'Through' is a preposition and does not convey the intended meaning of being heard in every part of the community.

Rationale: The correct term for the voice box is the larynx. The pharynx is part of the throat involved in swallowing and breathing but not the voice production. The trachea is the windpipe responsible for air passage, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, in this context, the larynx is the most appropriate term.

Correct Answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious means causing great harm or damage. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Infectious,' refers to the ability of a disease to spread. Choice D, 'Helpful,' is also the opposite of pernicious and does not capture the negative connotation associated with the term.
