1. B. 15h * 20 = 300 h
2. B. (180-120) * 70/120=35
3. C. Ink-18*30=540h, Pottery-15*20=300h, Silk-24*70=1680h. Total time Silk最大
4. B. 100*70/120=58.3

1. A.
段落分析：
Official A - railroad 是唯一contributor (关键词：solely)
Official B – 认同railroad价值（原文：acknowledges the importance of the railroad），但urban roadways and highways 同样有contribution
对比：对于contribution来源的认知有差异
问题：contention的不同是什么 – 即对比结果
(A) Whether the railroad was the only factor contributing to the United States' economic growth. 正确
(B) Whether urban roadways and highways were necessary for the United States' economic growth. 错误。AB的争论点不是这二者还是其他更多因素，而是是否只是railroad
(C) Whether economic growth would have occurred in the absence of the railroad expansion. 错误。B认同railroad价值，不是不认同
(D) Whether the government's role in facilitating transportation development was crucial. 错误。与gov无关。
(E) Whether other forms of transportation could have replaced the railroad's role in economic development. 错误。不是replacement，B认同railroad价值
2. E.
Argument: 让旅游者去太空参与实验任务有好处，好处是可以多多融资。提出的原因是，人们会倾向于投资他们认为有好处回报的事物（为什么去太空=有好处？）
现象：有些富翁已经投资太空项目 -> 这些项目已经允许他们进入太空。文章认为这暗示了其他投资者，进入太空是有明显的benefit的
问题：要评估argument，哪一个前提是最需要被定义的
(A) Whether the cost of including tourists on space research missions exceeds the additional funds raised. – 没有涉及到需要评估ROI
(B) Whether space tourism is the only potential benefit that can attract investment in space exploration. – 重点是，去太空是不是唯一的benefit？其实与投资动机有差距，因为政府的目的还是想拉拢投资
(C) Whether the multimillionaires' investment covers the total cost of their space travel experience. – 不需要评估钱本身的consumption
(D) Whether the number of interested tourists is sufficient to regularly contribute to space exploration funding. – 跟人数无关
(E) Whether investors without the opportunity to participate in space tourism would still invest in space exploration. – 与B类似，但重点落在“投资行为”本身的动机

文章结构：
Para1背景描述（大家多年前对于Enceladus的认知，icy surface）
Para2最近的研究（heat surface和其他适宜生物生长的元素，似乎是理想的生活区域）
Para3 与Earth的heat产生机理作对比（与radioactive decay对比有更重要的来源，Tidal heating，且与stripes的产生align了）
答案：
1. What is the main focus of the passage? 整个文章主旨？
A) The discovery and implications of Enceladus's geological activity. 正确。En星地理活动的发现和可能的影响
B) The comparison of Enceladus's surface with other Saturnian moons. 错误。没有提到其他土星的卫星
C) The role of Voyager 2 in unveiling Saturn's moon system. 错误。重点不在于如何发现的过程
D) The internal and external heat sources of Enceladus. 错误。没有讲到external heat
E) The potential for life on Saturn's moon Enceladus. 错误。第二段有聊到跟life的潜在影响，但不是整个文章的主旨
2. What did scientists find surprising about Enceladus? 意外之处？（主要与第二段相关）
A) Its large size relative to other moons. 错误。Size不是重点
B) Its lack of an atmosphere.错误。大气不是重点
C) Its geological activity despite its small size.正确。地理活动比较好的概括了
D) Its distance from Saturn.错误。距离不是重点
E) The brightness of its surface.错误。亮度不是重点
3. Based on the passage, what can be inferred about the significance of Enceladus in the solar system?太阳系里Enceladus的作用？
A) It has defied previous scientific expectations regarding moon activity.错误。与在太阳系中的作用无关
B) It is the largest moon in the Saturnian system.错误。不是最大
C) It is the only moon with evidence of geological activity.错误。全文没有提到过这是唯一一个
D) It may play a key role in understanding tidal heating effects.正确
E) It is primarily of interest for its unique orbital path.错误。轨道不是重点
4. Which statement would the author likely agree with regarding Enceladus's heat sources?正确观点
A) Radioactive decay is the sole source of Enceladus's internal heat.错误。Not sole.
B) Tidal heating is an unlikely cause of Enceladus's geologic features.错误。完全违背
C) Tidal heating from Saturn's gravity is a plausible source of heat on Enceladus.正确
D) The moon's geological activity is unrelated to Saturn's gravitational pull.错误。违背原文
E) Enceladus's heat is entirely explained by its proximity to Saturn.错误。没有如此肯定
5. If a scientist were to propose a study based on the findings in the passage, what would be a likely focus? 后期继续研究，肯定需要和文章最后的猜想挂钩。最后的猜想是Tidal heating和Saturn's gravity有关
A) Investigating the potential for life on other Saturnian moons. 正确
B) Measuring the radioactive substances on Enceladus.
C) Assessing the impact of Enceladus's orbit on its heat generation.
D) Comparing Enceladus's geology to Earth's lunar features.
E) Cataloging organic compounds present on Enceladus. |
