52. What does the author advise scientists do to deal with topics outside of their specialty?
- A. Write or present on them from new angles.
- B. Utilize information from diverse sources.
- C. Turn to a specialist for professional help.
- D. Fact-check with colleagues in their field.
答案：C
答案句：They need to recognize the constraints in their own knowledge. That is not to suggest that they only write or present on their own research, but rather, that they consult with an expert if the topic is outside of their discipline.
参考译文：他们需要认识到自己知识的局限性。这并不是说他们只写或展示自己的研究，而是说，如果主题超出他们的学科范围，他们应该咨询专家。
定位线索：题干“topics outside of their specialty”→答案句“topic is outside of their discipline”；文中“consult with an expert”对应选项C“Turn to a specialist for professional help”。
解析：答案句明确建议科学家在主题超出学科范围时咨询专家，与选项C“求助于专家获得专业帮助”同义。选项A“新角度”、B“多样信息源”无中生有；D“与同事核实”偷换概念，原文是咨询专家而非同事。
54. What does the example of the biologist who shared an intricate analogy show?
- A. It is helpful to use illustrations in explaining scientific phenomena.
- B. It is imperative to have appropriate titles to explain scientific issues.
- C. A learned scholar is not necessarily a qualified science communicator.
- D. A nonscientific audience cannot duly understand principles of science.
答案：C
答案句：It is equally imperative to emphasize that being an expert on a topic does not automatically make a scholar qualified to communicate it to a nonscientific audience. … One biologist shared an intricate analogy involving a library, books, paper, a recipe, ingredients, and a cake to explain the process behind vaccines. Any explanation that requires a written key to keep track of what each item represents is not a clear example for public consumption.
参考译文：同样必须强调的是，成为某个话题的专家并不会自动使学者有资格向非科学受众传播它。…一位生物学家分享了一个涉及图书馆、书籍、纸张、食谱、配料和蛋糕的复杂类比来解释疫苗背后的过程。任何需要书面说明来跟踪每个项目代表什么的解释都不是一个清晰的公众消费例子。
定位线索：题干“example of the biologist”→答案句“One biologist shared an intricate analogy”；例子前观点句“being an expert on a topic does not automatically make a scholar qualified”对应选项C“A learned scholar is not necessarily a qualified science communicator”。
解析：例子本身（生物学家复杂的类比）不是答案依据，例子前的观点句“成为专家不自动使学者有资格传播”才是关键，正确选项C正是该观点的同义转述。选项A“使用插图有帮助”与例子相反；B“有适当头衔”偷换概念；D“非科学受众不能理解”与原文矛盾。
