However, many countries, including China, which holds the world's largest rare earth reserves, have imposed restrictions on rare earth exports. To address the shortage of rare earth supply, it has been suggested that Japan should focus on recovering these elements from discarded products that contain them. Which of the following, if true, would most strongly support the argument that recovering rare earth elements from discarded products is a viable solution for Japan's rare earth shortage? (A) China's rare earth export restrictions are unlikely to be lifted in the near future. (B) Japan's high-tech industries are exploring alternative materials to replace rare earth elements. (C) The process of extracting rare earth elements from discarded products is more environmentally friendly than mining them. (D) There is an efficient and cost-effective method for extracting rare earth elements from discarded products. (E) The demand for rare earth elements in Japan's high-tech industries is expected to decrease in the coming years. A flower shop in the United States, which is the largest in the country, reports that a particular flower accounts for 30% of its total flower sales. Based on this information, the shop concludes that this flower is the most popular one planted in gardens across the nation. Which of the following, if assumed, would allow the flower shop's conclusion to be properly drawn? (A) The flower shop sells more than 50 different varieties of flowers belonging to the same family as the flower in question. (B) The majority of the flowers sold by the shop are purchased with the intention of being planted in gardens. (C) The flower shop's sales are representative of the overall flower market in the United States. (D) The flower in question is native to the United States and thrives in most climates across the country. (E) Other flower shops in the United States also report high sales volumes for the flower in question. DB From the foregoing discussion, it is apparent that porphyry copper deposits came into being as a result of special geological conditions. Much evidence has now been accumulated that leads us to suspect that the deposits were formed as lay-products of volcanic activity where deep-seated magma bodies had suitable compositions and properties and where crustal characteristics permitted those bodies to rise rapidly to shallower levels. The evidence is indirect, and hence inconclusive, however, because the volcanic structures that may once have existed above the deposits would have been topographically and compositionally unstable and thus would have been removed rapidly by weathering, and because a large percentage of known deposits are now exposed as a result of millions or tens of millions of years of erosion. Nevertheless, a volcanic origin for many porphyry copper deposits is consistent with the following facts. First, by far the greatest number of deposits are of Mesozoic age or younger—less about 230 million years old—and are located in either the “ring of fire,“ the belt of volcanoes and volcanic rocks that encircles the Pacific Ocean, or the “Tethyan” belt, the east-west band of volcanic rocks and mountains that extends throughout the southern Soviet Union and into the Middle East (Fig. 5). The association of the deposits with volcanic rocks and the style of occurrence are much the same in both regions. Moreover, both these parts of the world are currently the sites of much earthquake activity and volcanism, which are believed to be manifestations of the same sorts of events as are known to have occurred in or near these regions ever since about 230 million years ago. Second, although most of the rocks that existed at the time the ore was formed have been removed by erosion. there are a few deposits where remnants of volcanic rocks about the same-age as the porphyries (up to 200 million years old) are found, and where porphyries containing copper deposits are present as intrusions in the volcanic rocks (Fig. 6). This coincidence of porphyries and volcanic rocks in both time and space is strong evidence for a volcanic origin for the deposits. Third, the theory of the origin of porphyritic textures described previously involves two stages of cooling: an early stage, during which crystals of silicate minerals started to form, and a late stage, in which the residual magma was quenched to form a fine-grained matrix. The late stage of cooling was thought to be the result of magma rising rapidly to the cooler environment of the shallow crust. According to the volcanic genesis theory, the porphyry intrusions, which have compositions similar to those of many volcanic rocks, formed when magma rose rapidly toward the earth’s surface through the core of a volcano. Fourth, a large percentage of porphyry copper deposits contain bodies of breech—angular fragments of rock, which, in some instances, are cemented with fine crystalline volcanic-like rock or with rock “flour" derived from the mutual abrasion of porphyry fragments (Fig. 2). Such bodies are commonly irregular, essentially vertical columns, or “pipes,” with round or elliptical cross sections; less commonly, they assume a tabular form, such as that of a vertical sheet, or “dike.” The transportation and pulverization of rocks in breccias, as well as the geometry of the breccia bodies, suggest that there may have been an opening to the surface at the time that they formed. Moreover, breccias that look like these are present in active volcanic systems, where openings clearly exist. Fifth, the distribution of deposits in well-explored regions of the Pacific rim shows tendencies toward clustering, as in southwest North America. where clusters occur in areas about 30 km by 30km (Fig. 7), and toward formation along lines on the earth's surface, as in the Andes. Volcanoes show similar tendencies to cluster or form along lines. This similarity in distribution of volcanic centers and porphyry ore deposits is not in itself compelling evidence for an association, but taken together with the other pieces of evidence, it strengthens the case. The inferred link between circum-Pacific volcanism and the formation of porphyry ore deposits is extremely important, because it establishes a rational basis for searching for such deposits. Moreover, the high success rate—the discovery of more than a hundred new deposits—over the past two decades of searching premised in part on the assumption that the theory is correct attests in some measure to its validity. Question 1: According to the passage, which of the following is true about the volcanic structures that may have existed above porphyry copper deposits? (A) They were topographically and compositionally stable. (B) They were rapidly removed by weathering. (C) They are still present above most porphyry copper deposits. (D) They were formed millions of years after the porphyry copper deposits. (E) They have been well-preserved due to their resistance to erosion. Question 2: The passage suggests that the greatest number of porphyry copper deposits are found in: (A) The "ring of fire" and the "Tethyan" belt (B) Areas with little earthquake activity and volcanism (C) Regions where volcanic rocks are older than 230 million years (D) The northern Soviet Union and the Middle East (E) Areas with no association between deposits and volcanic rocks Question 3: Which of the following is mentioned in the passage as evidence for a volcanic origin of porphyry copper deposits? (A) The presence of remnants of volcanic rocks about the same age as the porphyries (B) The absence of intrusions in the volcanic rocks (C) The lack of coincidence of porphyries and volcanic rocks in both time and space (D) The dissimilar compositions of porphyries and volcanic rocks (E) The slow cooling of magma in the early stage of porphyry formation Question 4: According to the theory of the origin of porphyritic textures, the late stage of cooling is thought to be the result of: (A) Magma rising slowly to the warmer environment of the deep crust (B) Magma rising rapidly to the cooler environment of the shallow crust (C) Crystals of silicate minerals forming in the early stage (D) The residual magma being heated to form a coarse-grained matrix (E) The magma remaining stationary in the earth's mantle Question 5: The passage suggests that the transportation and pulverization of rocks in breccias, as well as the geometry of the breccia bodies, indicate: (A) The absence of an opening to the surface at the time of their formation (B) The presence of an opening to the surface at the time of their formation (C) The formation of breccias long after the porphyry copper deposits (D) The lack of similarity between these breccias and those in active volcanic systems (E) The slow and gradual formation of breccia bodies Question 6: According to the passage, the distribution of porphyry copper deposits in well-explored regions of the Pacific rim shows tendencies toward: (A) Uniform dispersion across large areas (B) Clustering and formation along lines on the earth's surface (C) Isolation from volcanic centers (D) Formation in areas with no volcanic activity (E) Random distribution without any discernible patterns Question 7: The passage suggests that the similarity in distribution of volcanic centers and porphyry ore deposits: (A) Is compelling evidence for an association between the two (B) Weakens the case for an association between the two (C) Is not related to the other pieces of evidence presented (D) Contradicts the theory of a volcanic origin for porphyry copper deposits (E) Strengthens the case for an association when considered with other evidence Question 8: The high success rate of discovering new porphyry copper deposits over the past two decades is attributed in part to: (A) The assumption that the theory linking circum-Pacific volcanism and porphyry ore deposits is incorrect (B) The lack of a rational basis for searching for such deposits (C) The assumption that the theory linking circum-Pacific volcanism and porphyry ore deposits is correct (D) The focus on searching in areas without any volcanic activity (E) The disregard for the evidence supporting a volcanic origin for porphyry copper deposits BAABBBEC Amidst the cataclysmic upheaval and the inexorable maelstrom of the Crusades, an epoch that indelibly etched itself upon the annals of history, the indomitable and zealous European forces, guided by the divine providence and the sacrosanct mandate of the Almighty, embarked upon a Herculean endeavor to wrest control of the hallowed lands of Christendom from the tenacious clutches of the infidel Muslim powers. Under the aegis of such luminaries as Pope Urban II, the charismatic and visionary pontiff who ignited the flames of holy war with his impassioned clarion call at the Council of Clermont in 1095, King Richard I of England, the legendary Lionheart renowned for his martial prowess and chivalric valor, and Emperor Frederick I Barbarossa, the formidable Teutonic ruler who sought to solidify his imperial hegemony and reassert the preeminence of the Holy Roman Empire, the Crusaders found themselves confronted with the monumental task of judiciously allocating their finite resources and assiduously formulating a comprehensive stratagem to unleash a decisive offensive against their implacable and resolute adversaries. The four paramount campaigns that consumed the Crusaders' every waking thought and galvanized their indefatigable efforts were the First Crusade (1096-1099), an audacious and unprecedented undertaking that culminated in the triumphant capture of Jerusalem and the establishment of the Latin Kingdom; the Second Crusade (1147-1149), a ill-fated and abortive venture that sought to bolster the beleaguered Crusader states in the Levant; the Third Crusade (1189-1192), an epic and titanic struggle between the redoubtable Richard the Lionheart and the indomitable Saladin for supremacy in the Holy Land; and the Fourth Crusade (1202-1204), a calamitous and ignominious debacle that witnessed the tragic sack of Constantinople and the sundering of Christendom. Each of these campaigns was subjected to a meticulous and exhaustive assessment, predicated upon five cardinal factors that would inexorably shape the outcome of the conflict and determine the fate of the Crusader enterprise: 1. The overarching and far-reaching religious, strategic, and symbolic significance of the geographical locations that constituted the cynosure of the Crusaders' aspirations, particularly the sacred city of Jerusalem, the eternal capital of the Kingdom of Heaven, and Constantinople, the resplendent metropolis that stood as the bulwark of Eastern Christendom. These cities, steeped in biblical history and suffused with spiritual import, played a pivotal role in the grand tapestry of the Crusades, their possession or loss holding the potential to decisively alter the balance of power between the warring faiths and to shape the destiny of empires. 2. The formidability, resilience, and near-impenetrability of the enemy's elaborate and entrenched defensive fortifications, which had been painstakingly constructed and assiduously maintained to thwart and repel any Crusader incursion. From the mighty walls of Jerusalem, a testament to the indomitable spirit and martial prowess of the Muslim defenders, to the Theodosian Walls of Constantinople, a marvel of military engineering that had withstood the ravages of time and the onslaught of countless besiegers, these bastions of resistance posed a formidable challenge to the Crusaders' aspirations of conquest and domination. 3. The intrinsic potential for a triumphant and inexorable Crusader advancement and territorial acquisition, a tantalizing prospect that promised to irrevocably shift the momentum of the conflict in their favor and to deal a devastating blow to the enemy's morale and cohesion. The capture of Jerusalem in 1099, a momentous event that sent shockwaves reverberating throughout the Muslim world and ignited a fervent outpouring of joy and exultation in Christendom, and the sack of Constantinople in 1204, a cataclysmic upheaval that rent asunder the fabric of Byzantine society and precipitated the inexorable decline of the once-mighty empire, stood as powerful testaments to the Crusaders' martial prowess and their unwavering commitment to their sacred cause. 4. The projected attrition rates and the anticipated consumption of precious and finite resources, both human and material, that would be required to secure a hard-fought victory and to maintain the initiative in the face of implacable opposition and inhospitable terrain. The staggering casualties suffered by the Crusaders during the protracted and sanguinary sieges of Antioch (1097-1098) and Acre (1189-1191), where countless lives were sacrificed upon the altar of religious fervor and martial glory, and the immense logistical challenges of provisioning and sustaining armies across vast distances and in hostile environments, served as sobering reminders of the immense cost and sacrifice that attended the pursuit of the Crusaders' divinely ordained mission. 5. The profound and far-reaching ramifications on the overall trajectory and outcome of the Crusades, a complex and multifaceted phenomenon that encompassed the military, political, economic, religious, and social dimensions of the conflict. From the establishment of the Latin Kingdom of Jerusalem, a bastion of Western Christendom in the heart of the Muslim world that would endure for nearly two centuries, to the Fourth Crusade's fateful diversion to Constantinople, a tragic miscalculation that ultimately led to the weakening of the Byzantine Empire and the irrevocable alienation of the Eastern Church, the consequences of the Crusaders' actions would reverberate through the ages, shaping the course of history and leaving an indelible mark upon the collective consciousness of humanity. To facilitate a rigorous and systematic evaluation of each campaign, the Crusader leadership employed a nuanced and granular scale, ranging from 1 (denoting the lowest level of strategic importance, operational feasibility, and potential impact) to 10 (signifying the highest degree of criticality, viability, and consequence). This quantitative assessment, derived from an exhaustive and meticulous analysis of historical chronicles, eyewitness accounts, and archaeological evidence, was complemented by a qualitative appraisal that drew upon the collective wisdom and insight of the Crusader high command. The esteemed and battle-hardened Crusader commanders, each possessed of their own unique strategic acumen, operational predilections, and martial philosophies, engaged in a spirited and impassioned discourse to determine the optimal allocation of resources and manpower. From the visionary and charismatic Pope Urban II, whose clarion call to arms galvanized the faithful and set in motion the First Crusade, to the valiant and chivalrous King Richard the Lionheart, whose martial prowess and strategic genius were the stuff of legend, to the cunning and pragmatic Doge Enrico Dandolo of Venice, whose machinations and intrigues would ultimately seal the fate of the Fourth Crusade, these luminaries brought to bear their formidable intellects and their wealth of experience in the service of their sacred cause. Cognizant of the grave responsibility that rested upon their shoulders, the weighty mantle of leadership that they had assumed in the name of Christendom, and the divine mandate that compelled them to wage a holy war against the infidel, the Crusader commanders assiduously pored over ancient prophecies and scriptural exegeses, seeking to discern the signs and portents that would guide their steps and illuminate their path. They studied the art of war as practiced by the great generals of antiquity, from Alexander the Great to Julius Caesar, and sought to apply the timeless principles of strategy and tactics to the unique challenges and opportunities presented by the Crusades. In their deliberations, the Crusader leaders were ever mindful of the multifaceted and often inscrutable geopolitical implications of their actions, the delicate web of alliances and rivalries that spanned the Mediterranean world, and the shifting sands of power and influence that could make or break their enterprise. They grappled with the competing demands of piety and pragmatism, of idealism and realpolitik, as they sought to chart a course that would balance the imperatives of faith with the exigencies of statecraft. Ultimately, the Crusades would leave an indelible mark upon the fabric of history, a complex and contested legacy that would endure for centuries and continue to shape the world we inhabit today. The heroic deeds and tragic follies of the Crusaders, their triumphs and their failures, their nobility and their barbarism, would become the stuff of legend, inspiring generations of poets, artists, and dreamers, and provoking endless fascination, admiration, and revulsion in equal measure. And though the Crusades may have ended in defeat and disillusionment, the spirit of the Crusaders – their courage, their devotion, their unyielding commitment to a higher cause – would live on, a testament to the enduring power of faith, the indomitable resilience of the human spirit, and the eternal struggle between the forces of light and darkness that lies at the heart of the human condition.
