In food chains, species at higher trophic levels tend to have heavier isotope ratios in their bodies. The researchers hypothesize that this change occurred because the penguins shifted from a diet composed primarily of fish to one composed primarily of krill during this time period. They cite as evidence the fact that populations of whales and another krill-eating species declined during this period, likely leading to a dramatic increase in the krill population. Which of the following is an assumption on which the researchers' conclusion depends? (A) The penguins' fish prey has a higher trophic level than the penguins themselves. (B) Krill have sufficient nutritional value to be a viable primary food source for this penguin species. (C) This penguin species prefers to eat fish and only consumes krill when fish populations are low. (D) The carbon isotope ratios in the penguins' bodies would not have shifted if both krill and fish were scarce. (E) The whale and the other krill-eating species declined solely due to the increase in this penguin species' krill consumption. In a certain region, the incidence of stomach cancer is remarkably low. A study revealed that a particular vegetable is a staple in the diet of this population. The researchers therefore hypothesized that a compound found in this vegetable may lower the risk of developing stomach cancer. Which of the following, if true, would most weaken the researchers' hypothesis? (A) People in this region begin consuming this vegetable at a very young age. (B) The vegetable is cooked using a method that is believed to destroy some of its nutritional value. (C) The vegetable is typically consumed in combination with a food that has been linked to an increased risk of stomach cancer. (D) Other populations with similarly low rates of stomach cancer do not consume this vegetable regularly. (E) Consuming the vegetable in its raw form can lead to stomach discomfort, prompting more frequent medical check-ups that enable early detection of stomach cancer. BE 2.RC Knowledge of the intense heat and pressure in the mantle led researchers to hypothesize in the late 1960s that ocean crust originates as tiny amounts of liquid rock known as melt—almost as though the solid rocks were “sweating.” Even a minuscule release of pressure (because of material rising from its original position) causes melt to form in microscopic pores deep within the mantle rock. Explaining how the rock sweat gets to the surface was more difficult. Melt is less dense than the mantle rocks in which it forms, so it will constantly try to migrate upward, toward regions of lower pressure. But what laboratory experiments revealed about the chemical composition of melt did not seem to match up with the composition of rock samples collected from the mid-ocean ridges, where eruptedmelt hardens. Using specialized equipment to heat and squeeze crystals from mantle rocks in the laboratory, investigators learned that the chemical composition of melt in the mantle varies depending on the depth at which it forms; the composition is controlled by an exchange of atoms between the melt and the minerals that makeup the solid rock it passes through. The experiments revealed that as melt rises, it dissolves one kind of mineral, orthopyroxene, and precipitates, or leaves behind, another mineral, olivine. Researchers could thus infer that the higher in the mantle melt formed, the more orthopyroxene it would dissolve, and the more olivine it would leave behind. Comparing these experimental findings with lava samples from the mid-ocean ridges revealed that almost all of them have the composition of melts that formed at depths greater than 45kilometers. This conclusion spurred a lively debate about how meltis able to rise through tens of kilometers of overlying rock while preserving the composition appropriate for a greater depth. If melt rose slowly in smallpores in the rock, as researchers suspected, it would be logical to assume that all melts would reflect the composition of the fashallowest part of the mantle,at 10 kilometers or less. Yet the composition of most mid-ocean ridge lavas amples suggests their source melt migrated through the uppermost 45 kilometers of the mantle without dissolving any orthopyroxene from the surrounding rock. But how? In the early 1970s scientists proposed an answer: the melt must make the last leg of its upward journey along enormous cracks. Open cracks would allow the melt to rise so rapidly that it would not have time to interact with the surrounding rock, nor would melt in the core of the crack ever touch the sides. Although open cracks are not a natural feature of the upper mantle— the pressure is simply too great—some investigators suggested that the buoyant force of migrating melt might sometimes be enough to fracture the solid rock above, like an icebreaker ship forcing its way through polar pack ice. Adolphe Nicolas of the University of Montpellier in France and his colleagues discovered tantalizing evidence for such cracks while examining unusual rock formations called ophiolites. Typically, when oceanic crust gets old and cold, it becomes so dense that it sinks back into the mantle along deep trenches known as subduction zones, such as those that encircle the Pacific Ocean. Ophiolites, on the other hand, are thick sections of old seafloor and adjacent, underlying mantle that are thrust up onto continents when two of the planet’s tectonic plates collide. A famous example, located in the Sultanate of Oman, was exposed during the ongoing collision of the Arabian and Eurasian plates. In this and other ophiolites, Nicolas’s team found unusual, light-colored veins called dikes, which they interpreted as cracks in which melt had crystallized before reaching the seafloor. The problem with this interpretation was that the dikes are filled with rock that crystallized from a melt that formed in the uppermost reaches of the mantle, not below 45 kilometers, where most mid-ocean ridge lavas originate. In addition, the icebreaker scenario may not work well for the melting region under mid-ocean ridges: below about 10 kilometers, the hot mantle tends to flow like caramel left too long in the sun, rather than cracking easily. To explain the ongoing mystery, I began working on an alternative hypothesis for lava transport in the melting region. In my dissertation in the late 1980s, I developed a chemical theory proposing that as rising melt dissolves orthopyroxene crystals, it precipitates a smaller amount of olivine, so that the net result is a greater volume of melt. Our calculations revealed how this dissolution process gradually enlarges the open spaces at the edges of solid crystals, creating larger pores and carving a more favorable pathway through which melt can flow. As the pores grow, they connect to form elongate channels. In turn, similar feedbacks drive the coalescence of several small tributaries to form larger channels. Indeed, our numerical models suggested that more than 90 percent of the melt is concentrated into less than 10 percent of the available area. That means millions of microscopic threads of flowing melt may eventually feed into only a few dozen, high porosity channels 100 meters or more wide. Even in the widest channels, many crystals of the original mantle rock remain intact, congesting the channels and inhibiting movement of the fluid. That is why melt flows slowly, at only a few centimeters a year. Over time, however, so much melt passes through the channels that all the soluble orthopyroxene crystals dissolve away, leaving only crystals of olivine and other minerals that the melt is unable to dissolve. As a result, the composition of the melt within such channels can no longer adjust to decreasing pressure and instead records the depth at which it last “saw” an orthopyroxene crystal. One of the most important implications of this process, called focused porous flow, is that only the melt at the edges of channels dissolves orthopyroxene from the surrounding rock; melt within the inner part of the conduit can rise unadulterated. Q1. The author's discussion of the chemical composition of melt in the mantle serves to: (A) Challenge the prevailing theory about the origin of ocean crust in the late 1960s (B) Provide context for understanding the significance of the author's focused porous flow hypothesis (C) Demonstrate the limitations of laboratory experiments in replicating mantle conditions (D) Emphasize the importance of ophiolites in studying mantle processes (E) Illustrate the complex interplay between temperature, pressure, and chemical reactions in the mantle Q2. The passage implies that the focused porous flow hypothesis, if true, would account for which of the following? (A) The presence of ophiolites on continental surfaces (B) The absence of orthopyroxene crystals in mid-ocean ridge lava samples (C) The slow rate of melt flow through the mantle (D) The difference in chemical composition between shallow and deep melt in the mantle (E) The fracturing of solid rock by the buoyant force of migrating melt Q3. The author's argument in the final paragraph depends on all of the following EXCEPT: (A) The dissolution of orthopyroxene crystals results in a net increase in the volume of melt (B) Melt flow through the mantle is slowed by the presence of solid crystals in the channels (C) The composition of melt in the inner part of a channel is unaffected by changes in pressure (D) Melt in the mantle is concentrated into a small fraction of the available space (E) The chemical composition of melt in the mantle is determined by the depth at which it forms Q4. The author's hypothesis about focused porous flow would be most seriously undermined if which of the following were true? (A) The chemical composition of melt in the mantle is primarily determined by temperature rather than pressure (B) Ophiolites are found to contain a higher proportion of orthopyroxene than olivine (C) Melt in the mantle rises at a rate of several meters per year rather than a few centimeters (D) The dissolution of orthopyroxene does not significantly increase the porosity of the surrounding rock (E) Channels in the mantle are frequently obstructed by the precipitation of minerals other than olivine Q5. The passage suggests that the primary reason why the icebreaker scenario may not adequately explain the transport of melt through the mantle is that: (A) The buoyant force of melt is insufficient to fracture the overlying rock (B) The dikes found in ophiolites are composed of melt that formed at shallow depths (C) Open cracks are unlikely to form naturally in the mantle below a certain depth (D) The composition of melt in the dikes does not match that of mid-ocean ridge lavas (E) Ophiolites are not representative of the conditions under which most oceanic crust forms Q6. According to the passage, laboratory experiments on mantle rocks have revealed that: (A) The chemical composition of melt in the mantle is primarily controlled by temperature (B) Melt in the mantle becomes more enriched in orthopyroxene as it rises to shallower depths (C) The exchange of atoms between melt and the surrounding rock is influenced by pressure (D) The mineral olivine is more soluble in melt than orthopyroxene at all depths in the mantle (E) The composition of melt in the mantle varies depending on the depth at which it forms Q7. The author introduces the concept of "rock sweat" (line 3) in order to: (A) Explain how melt is initially formed within the mantle (B) Contrast the properties of melt with those of solid mantle rock (C) Describe the slow rate at which melt migrates through the mantle (D) Illustrate the challenges faced by early researchers in studying mantle processes (E) Emphasize the role of pressure changes in the formation of ocean crust Q8. Which of the following can be inferred from the passage about the relationship between the "open spaces at the edges of solid crystals" and the "elongate channels" mentioned in the final paragraph? (A) The open spaces are the primary source of the melt that flows through the elongate channels (B) The elongate channels are formed by the coalescence of the open spaces over time (C) The open spaces and elongate channels are found in different regions of the mantle (D) The elongate channels are destroyed by the precipitation of olivine in the open spaces (E) The formation of open spaces is inhibited by the presence of elongate channels nearby 答案: (B) 解析: 作者讨论地幔熔体的化学成分，是为了给读者提供背景知识，以便理解作者提出的"集中多孔流"假说的重要性。通过解释熔体成分如何随深度变化，以及这与中洋脊熔岩样本的成分不一致，作者为引入自己的新假说做铺垫。其他选项虽然都与文章内容有一定关系，但都不是作者讨论熔体成分的主要目的。 答案: (B) 解析: 根据文章最后一段，"集中多孔流"假说的一个重要含义是，只有在通道边缘的熔体才会从周围岩石中溶解斜方辉石（orthopyroxene）结晶体，而通道内部的熔体可以不受影响地上升。这意味着，如果该假说是正确的，那么中洋脊熔岩样本中应该缺乏斜方辉石结晶体。其他选项虽然都与文章内容有一定关系，但都不是"集中多孔流"假说直接解释的现象。 答案: (E) 解析: 作者在最后一段中提出"集中多孔流"假说，其论证依赖于以下几点：溶解斜方辉石会导致熔体体积净增加；熔体在通道中的流动被固体结晶所阻碍；通道内部熔体的成分不受压力变化的影响；大部分熔体集中在很小一部分可用空间中。而选项E提到的"熔体的化学成分取决于形成深度"这一点，虽然在文章前面部分有所论述，但并不是最后一段论证的必要条件。因此，E是论证不依赖的一点，是正确答案。 答案: (D) 解析: 根据最后一段，作者的"集中多孔流"假说的一个关键环节是，随着上升的熔体溶解斜方辉石结晶体，它会沉淀出较少量的橄榄石，从而导致熔体体积净增加，逐渐扩大固体结晶体边缘的开放空间，创造出更大的孔隙和更有利的通道。如果选项D是真的，即溶解斜方辉石并不显著增加周围岩石的孔隙度，那么这一关键环节就不成立，从而最严重地削弱作者的假说。其他选项虽然可能对作者的假说造成一定挑战，但都没有选项D那样直接动摇假说的基础。 答案: (C) 解析: 文章第三段提到，Nicolas和同事在蛇纹岩（ophiolites）中发现了一些不寻常的浅色岩脉（dikes），他们将其解释为熔体在到达海底之前结晶的裂缝。但是这种解释存在两个问题：一是这些岩脉充填的岩石结晶自很浅部的熔体，而不是大多数中洋脊熔岩的起源深度（45公里以下）；二是"破冰船情景"可能不太适用于中洋脊下的熔融区域，因为在大约10公里以下，由于高温，地幔倾向于像"太阳下久置的焦糖"一样流动，而不是轻易开裂。这两个问题中，第二个更直接地指出了"破冰船情景"不适用的主要原因，即在一定深度以下，地幔不太可能自然形成开放的裂缝。因此，选项C是正确答案。其他选项虽然也提到了"破冰船情景"的一些问题，但都不是文章强调的主要原因。 答案: (E) 解析: 根据文章第二段，使用特殊设备在实验室中加热和挤压地幔岩石中的晶体，研究人员发现，地幔熔体的化学成分随着形成深度的不同而变化；这种成分变化是由熔体与其通过的固体岩石之间的原子交换所控制的。实验表明，随着熔体上升，它溶解一种矿物质斜方辉石，而沉淀另一种矿物质橄榄石。因此，研究人员可以推断，熔体形成的高度越高，它溶解的斜方辉石就越多，留下的橄榄石也就越多。这与选项E的表述完全一致，其他选项都没有准确反映实验的发现。 答案: (A) 解析: 在文章第一段，作者引入了"岩石汗水"（rock sweat）的概念，指出20世纪60年代晚期，研究人员根据对地幔中高热和高压的了解，提出了这样一种假设：洋壳起源于被称为熔体（melt）的少量液态岩石，就好像固态岩石在"出汗"一样。哪怕是极小的压力释放（由于物质从原来的位置上升），也会导致熔体在地幔岩石深处的微观空隙中形成。这段文字清楚地表明，"岩石汗水"这个比喻是用来解释熔体最初是如何在地幔内部形成的。其他选项虽然都与熔体的某些特性有关，但都不是引入"岩石汗水"概念的主要目的。 答案: (B) 解析: 在文章最后一段，作者提出，随着上升的熔体溶解斜方辉石结晶体，它会沉淀出较少量的橄榄石，从而导致固体结晶边缘开放空间的逐渐扩大，创造出更大的孔隙和更有利的通道。随着孔隙的增长，它们连接形成细长的通道。反过来，类似的反馈驱动几个小支流汇合形成更大的通道。这段文字表明，细长的通道是由开放空间随时间推移合并而成的。文章没有明确说明开放空间和细长通道之间的其他关系，因此其他选项都无法从文章中推断出来。 3.DI In the labyrinthine world of luxury fragrance, where venerable houses with centuries-old pedigrees reign supreme, the meteoric rise of Jo Malone London (JML) is a testament to the power of artisanal craftsmanship, olfactory innovation, and strategic adaptability. Founded in 1994 by British perfumer Joanne Lesley Malone, this niche perfume house has not only managed to carve out a distinct identity in an intensely competitive market but has also navigated the tempestuous waters of shifting consumer preferences, economic volatility, and global crises with remarkable resilience. The allure of JML lies in its unwavering commitment to creating scents that are at once ethereal and grounded, evocative and understated. Eschewing the ostentatious opulence that characterizes many luxury fragrances, JML's creations are imbued with a sense of minimalist elegance, focusing on the interplay of high-quality, natural ingredients to craft olfactory experiences that are both subtle and sublime. This artisanal approach, rooted in Malone's own philosophy of "fragrance as a form of self-expression," has resonated deeply with a new generation of consumers who prioritize authenticity, personalization, and sensory exploration. The ascendancy of JML is inextricably linked to the seismic shifts in consumer behavior that have reshaped the luxury landscape in recent years. As millennials and Gen Z have emerged as the dominant forces in the market, their penchant for experiences over possessions, their embrace of niche and artisanal brands, and their desire for products that align with their values have fundamentally altered the rules of the game. A 2019 report by NPD Group underscores this generational shift, revealing that prestige fragrance sales in the US grew by 4%, reaching $4.3 billion, with niche brands like JML driving much of this growth. Notably, 48% of consumers aged 18-24 expressed a preference for unique, lesser-known fragrances over mainstream options, a trend that has only gained momentum in the intervening years. However, the path to success for JML has been far from linear, punctuated by myriad challenges and upheavals that have tested the brand's mettle. The COVID-19 pandemic, in particular, has been a crucible for the luxury fragrance industry, exposing vulnerabilities and accelerating pre-existing trends. With McKinsey & Company estimating a staggering 35-39% decline in luxury sales in 2020, brands have had to swiftly adapt to a new reality defined by e-commerce, digital engagement, and supply chain disruptions. For JML, this has meant a 200% surge in online sales during the pandemic, even as its brick-and-mortar stores remained shuttered. This agility in the face of adversity, underpinned by a robust digital infrastructure and a loyal customer base, has been a key factor in the brand's resilience. Sustainability has also emerged as a defining issue for the luxury fragrance industry, as consumers become increasingly attuned to the environmental and ethical impact of their purchases. A 2020 survey by Cosmetics Business revealed that 75% of UK consumers consider sustainability when buying beauty products, a sentiment that is mirrored across global markets. For JML, this has necessitated a comprehensive reevaluation of its practices, from sourcing to packaging to product development. The brand has pledged to use 100% recyclable packaging by 2025 and has introduced a refill program to minimize waste. Moreover, it has intensified its focus on natural and organic ingredients, partnering with sustainable suppliers and supporting conservation efforts in key sourcing regions. As JML navigates this ever-shifting landscape, it must also contend with the rise of a new breed of niche fragrance houses that are vying for the same discerning consumers. Brands like Le Labo, Byredo, and Maison Margiela have emerged as formidable competitors, each with its own distinct aesthetic and narrative. To maintain its edge, JML has doubled down on its core strengths – artisanal craftsmanship, olfactory innovation, and emotional resonance – while also embracing collaboration and experimentation. Its partnerships with artists, designers, and cultural institutions have yielded some of its most acclaimed and sought-after scents, such as the Wild Bluebell collection, inspired by the works of British sculptor Barbara Hepworth, and the English Oak series, a tribute to the majestic trees of England's forests. Looking ahead, the future of the luxury fragrance industry is one of both challenge and opportunity. With Euromonitor International projecting a 3.4% CAGR from 2020 to 2025, there is ample room for growth and innovation. However, success will require a delicate balancing act between heritage and innovation, exclusivity and accessibility, local resonance and global appeal. For Jo Malone London, this means staying true to its artisanal roots while continuously pushing the boundaries of what is possible in the realm of fragrance. It means engaging with its customers on a deeper, more emotional level, creating scents that not only please the senses but also tell stories, evoke memories, and inspire dreams. And it means leading the charge on sustainability, transparency, and ethical practices, setting a new standard for the industry as a whole. In the final analysis, the ascent of Jo Malone London is a story of passion, resilience, and the enduring power of the human spirit. It is a reminder that even in the face of daunting odds and uncharted territories, those who dare to dream big, to stay true to their vision, and to adapt to the winds of change can achieve the extraordinary. As the brand continues to grow and evolve, it will undoubtedly face new challenges and opportunities, but one thing is certain: the legacy of Joanne Lesley Malone, and the artisanal spirit she imbued into every bottle of Jo Malone London fragrance, will continue to inspire and enchant for generations to come.
