Correct Answer: B

Rationale: Cicadas make a buzzing sound primarily to attract a mate. This sound is a mating call produced by the males to attract females for reproduction. While echolocation is used by some animals like bats for navigation, cicadas do not use buzzing for orientation. Buzzing is not related to locating a food source or warding off predators in the case of cicadas.

Correct Answer: D

Rationale: The main idea conveyed in the extract is that Shia encounters a terrifying situation in the CFO's office. The passage describes Shia hearing strange noises, feeling fear, and encountering alarming events like crashes and howls. This builds tension and indicates a dangerous situation unfolding. Choices A, B, and C are incorrect as they do not capture the central theme of Shia facing a frightening encounter in the CFO's office.

Correct Answer: C

Rationale: 'Erroneously' means incorrectly or mistakenly, which aligns with the context provided in the passage. Therefore, 'Incorrectly' and 'Mistakenly' are synonyms for 'erroneously.' 'Inconsequentially' means not resulting in any significant consequence, which is not synonymous with 'erroneously.' 'Extraneously' means irrelevant or unnecessary, which is also not a synonym for 'erroneously.'

Correct Answer: C

Rationale: The correct answer is C. The reference to sending a text message in the passage is a clear indication of the 21st century. This action of sending a text message is a modern communication method commonly associated with contemporary times. Choices A, B, and D do not provide any specific details or actions that distinctly tie them to the 21st century. Choice A focuses on the location of an office, which does not inherently place the passage in a specific time period. Choice B uses a metaphorical reference to Medusa, which is a mythological figure not limited to any particular era. Choice D describes a scene involving running to a parking garage, which could occur in various time periods without indicating a specific century.

Correct Answer: A

Rationale: The word 'avian' refers to birds, so the synonym is 'Bird.' In the provided passage, the term 'avian' is used to refer to birds, making 'Bird' the correct synonym. 'Flying' and 'Aerial' are related to the concept of flight but do not specifically refer to birds. 'Plane' refers to an aircraft and is not synonymous with 'avian' or 'bird.' Therefore, 'Bird' is the most appropriate choice as a synonym for avian in this context.
