Correct Answer: B

Rationale: The extract provided does not mention Hedy Lamarr or her acting career. Therefore, we cannot draw any conclusions about her from this text. Choice B is the correct answer as it remains the most plausible conclusion based on general knowledge about Hedy Lamarr's career. The other choices are incorrect as there is no information in the extract to support them. Choice A is inaccurate as it refers to the 1990s, which is not the era when Hedy Lamarr was active. Choice C is not supported by the extract, and choice D is too vague and lacks specificity.

Correct Answer: C

Rationale: The most relevant source for data on the effects of mobile use on consumers' hearing would be a university research paper about decibel limits of headphones and speakers. This source would provide specific information on how mobile use could potentially impact hearing due to the sound levels produced by headphones and speakers. Choice A discusses surcharges on bills, which is unrelated to hearing effects. Choice B focuses on the incidence of hearing loss in general, not specifically related to mobile use. Choice D, a statistical report on mobile phone usage, may not directly address the impact on consumers' hearing.

Correct Answer: C

Rationale: 'After' is used to indicate that one event happened following another in time. In the context of a timeline, 'After' signifies the sequence of events, showing what occurred subsequent to a particular point in time. In the provided extract, events unfold in a specific order, with each event happening 'after' the previous one. Choices A, B, and D do not inherently convey the idea of chronological order and are not suitable for indicating the sequence of events in a timeline.

Correct Answer: A

Rationale: The examples of plastic's advantages and difficulties in recycling show why the topic is divisive. The passage mentions that plastic has advantages, but it is difficult to recycle efficiently, indicating a conflict between the benefits and environmental impact of plastics. This conflict contributes to the divisive nature of discussions surrounding the use of plastics. Choices B, C, and D do not provide contrasting examples that highlight the divisive nature of the topic.

Correct Answer: A

Rationale: The correct answer is A, 'An interesting birthday party.' The passage describes Dr. Oliver Creekstone's remarkable 90th birthday party at his countryside estate, featuring unusual elements like zebras, monster trucks, and a bagpipe player. The guests were surprised by the buffet of boiled asparagus and pickled carrots, and the evening ended with a spectacular fireworks display. Choice B, 'A disappointing buffet menu,' is incorrect as the buffet is just one aspect of the overall event. Choice C, 'Dr. Creekstone's eccentricities,' while partially relevant, does not capture the main focus of the passage. Choice D, 'The lack of adequate lighting at the estate,' is unrelated to the topic of the excerpt.
