The Metropolitan Transit Authority (MTA) recently conducted a study showing that ridership on the Blue Line train after 5 PM on Fridays is significantly lower than at other times, resulting in operating losses. A proposal was made to discontinue Blue Line service after 5 PM on Fridays to reduce costs. However, the MTA board rejected this proposal.
Which of the following, if true, would best explain the board's decision to reject the proposal?
A) Many Blue Line riders after 5 PM on Fridays are returning home after having used the train for their morning commute.
B) The Blue Line's fixed costs, such as track maintenance and staff salaries, would remain largely unchanged even if Friday evening service were discontinued.
C) Ridership on other train lines in the system increases significantly after 5 PM on Fridays.
D) The Blue Line is the only public transportation option available for some communities along its route.
E) A survey indicated that most current Blue Line riders would switch to using private vehicles if Friday evening service were discontinued.

The government of Aquaterra, a region known for its agricultural economy, auctioned water rights to various villages decades ago. To increase long-term tax revenue from farming, the government is now considering deregulating these water rights, allowing villages to freely buy and sell them. Proponents argue that this will incentivize farmers to use water rights more profitably.
Which of the following would be most important to evaluate in determining whether this policy will achieve its intended goal of increasing long-term tax revenue from farming?
A) Whether the transactions from water rights sales will be subject to taxation.
B) The potential impact on villages that currently hold water rights but are not utilizing them efficiently.
C) The percentage of farmers who support the proposed deregulation of water rights.
D) Whether the increased profitability from water rights trading will outweigh any potential decrease in agricultural output from farms that sell their rights.
E) The environmental impact of potentially redistributing water usage across different areas of Aquaterra.

2.RC
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.

1. The passage implies that the volcanic genesis theory has been supported by
(A) direct observations of porphyry copper deposits forming in modern volcanic environments
(B) the discovery of porphyry copper deposits in regions without any known volcanic activity
(C) the successful prediction and discovery of new porphyry copper deposits based on the theory's principles
(D) the identification of ancient volcanic rocks that are consistently younger than nearby porphyry copper deposits
(E) the presence of unaltered volcanic rocks surrounding most porphyry copper deposits

2. Which of the following, if true, would provide the strongest support for the volcanic genesis theory of porphyry copper deposits?
(A) The discovery of a large porphyry copper deposit in an area with no known history of volcanic activity
(B) The identification of a genetic link between the formation of porphyry copper deposits and the crystallization of silicate minerals
(C) The observation of a porphyry copper deposit forming in real-time beneath an active volcano
(D) The determination that most porphyry copper deposits are located at depths of several kilometers beneath the Earth's surface
(E) The development of a new geophysical technique that can detect the presence of porphyry copper deposits without drilling

3. The passage suggests that the Mesozoic age of many porphyry copper deposits is significant because
(A) it coincides with a period of increased volcanic activity in the Earth's history
(B) it predates the formation of the "ring of fire" and the "Tethyan belt"
(C) it allows sufficient time for the removal of overlying volcanic structures by erosion
(D) it indicates that porphyry copper deposits are no longer forming in the present day
(E) it suggests that porphyry copper deposits are related to the breakup of the supercontinent Pangaea

4. The author's use of the term "quenched" in the context of the two-stage cooling process of porphyritic textures most likely refers to
(A) the rapid cooling and solidification of magma
(B) the slow crystallization of silicate minerals
(C) the formation of a fine-grained matrix surrounding larger crystals
(D) the alteration of primary minerals by hydrothermal fluids
(E) the fragmentation of rocks during the formation of breccia bodies

5. The passage suggests that the exposure of many porphyry copper deposits at the Earth's surface is primarily a result of
(A) the exhumation of the deposits by tectonic forces
(B) the removal of overlying rocks by weathering and erosion
(C) the uplift of the deposits during the formation of mountain ranges
(D) the depletion of the deposits by mining activities
(E) the deposition of the deposits in shallow marine environments

(C) illustrate the importance of mechanical weathering in the formation of porphyry copper deposits
(D) suggest that breccia bodies are formed by the grinding of porphyry fragments against each other
(E) argue for the existence of open spaces within porphyry copper deposits during their formation

7. The passage implies that the recognition of a link between circum-Pacific volcanism and porphyry copper deposits has
(A) led to a decrease in the exploration efforts for porphyry copper deposits
(B) prompted a reevaluation of the volcanic genesis theory
(C) provided a framework for the targeted exploration of porphyry copper deposits
(D) resulted in the discovery of porphyry copper deposits in regions far from the "ring of fire"
(E) challenged the idea that porphyry copper deposits are formed by magmatic processes

8. Which of the following statements best represents the author's perspective on the relationship between the distribution of volcanic centers and porphyry copper deposits?
(A) The similar distribution patterns provide conclusive evidence for a genetic link between the two.
(B) The distribution patterns are merely coincidental and do not reflect a causal relationship.
(C) The distribution patterns, while suggestive, are not sufficient evidence on their own for a volcanic origin of porphyry copper deposits.
(D) The distribution patterns are the result of the preferential preservation of porphyry copper deposits in regions with low volcanic activity.
(E) The distribution patterns reflect the influence of regional tectonic settings on the formation of both volcanic centers and porphyry copper deposits.

The venerable Château Lafite Rothschild, a bastion of viticultural excellence and one of the most illustrious wine estates in the world, has long been synonymous with unparalleled quality, finesse, and prestige. Nestled in the heart of the Pauillac appellation in the Bordeaux region of France, this iconic estate has been producing some of the most sought-after and highly acclaimed wines for over 150 years. The château's unwavering dedication to crafting wines of exceptional caliber, coupled with its rich history and tradition, has solidified its position as a true icon in the realm of fine wine.

The origins of Château Lafite Rothschild can be traced back to the 17th century when the Ségur family acquired the estate. Under their stewardship, the vineyard flourished, and the wines garnered a reputation for their unrivaled quality. In 1868, Baron James de Rothschild, the patriarch of the renowned Rothschild banking family, purchased the estate, ushering in a new era of prosperity and innovation. The Rothschilds, known for their business acumen and discerning taste, recognized the immense potential of the terroir and invested heavily in modernizing the winemaking facilities and techniques.

The terroir of Château Lafite Rothschild is truly exceptional, with its unique combination of gravel, sand, and limestone soils providing the ideal conditions for the cultivation of Cabernet Sauvignon, Merlot, Cabernet Franc, and Petit Verdot grapes. The estate's 112 hectares of vineyards are meticulously tended to by a dedicated team of viticulturists who employ sustainable and precision farming techniques to ensure the health and quality of the vines. The average age of the vines is an impressive 39 years, with some plots boasting vines that are over a century old, contributing to the complexity and depth of the wines.

The winemaking process at Château Lafite Rothschild is a testament to the estate's commitment to excellence and attention to detail. The grapes are hand-harvested at optimal ripeness and subjected to a rigorous selection process to ensure only the finest fruit makes its way into the final blend. The state-of-the-art winemaking facility, equipped with temperature-controlled stainless steel tanks and French oak barrels, provides the ideal environment for the fermentation and aging of the wines. The château's cellar master, Eric Kohler, oversees the entire process, drawing upon his wealth of experience and expertise to craft wines of unparalleled finesse and elegance.

The flagship wine of Château Lafite Rothschild, known simply as "Lafite," is a masterpiece of winemaking, embodying the essence of the Pauillac terroir and the estate's unwavering pursuit of perfection. This iconic red wine, typically composed of 80-95% Cabernet Sauvignon, 5-20% Merlot, and small amounts of Cabernet Franc and Petit Verdot, is renowned for its remarkable complexity, depth, and ageability. The wine's hallmark characteristics include a deep ruby color, enticing aromas of blackcurrant, cedar, and graphite, and a palate that is both powerful and refined, with seamlessly integrated tannins and a persistent, elegant finish. Lafite is a wine that truly epitomizes the concept of "iron fist in a velvet glove," with its ability to combine strength and finesse in perfect harmony.

In addition to the grand vin, Château Lafite Rothschild also produces a second wine, Carruades de Lafite, which was introduced in the 1850s. Carruades de Lafite is crafted from younger vines and parcels that do not make it into the final blend of the grand vin, offering a more approachable and earlier-drinking expression of the estate's terroir. While more accessible in terms of price and style, Carruades de Lafite still showcases the same level of care and attention to detail that goes into the production of the grand vin.
