1.CR

Scientists recently determined that the wood used to construct a house in Town B dates back 800 years. The scientists' dating method has a margin of error of only 50 years. This makes the house in Town B older than a house in Town K, which was previously thought to be the oldest after being dated at 700 years old.
Which of the following is an assumption underlying the scientists' conclusion?
(A) The wood used to build the house in Town B was not stored for an extended period after the trees were felled.
(B) The dating method used for the house in Town K is less accurate than the method used for the house in Town B.
(C) No other houses in the region are as old as the house in Town B.
(D) The wood used to construct the house in Town B came from the same forest as the wood used for the house in Town K.
(E) Houses built 800 years ago typically used freshly felled timber rather than wood that had been stored or seasoned.

According to a recent survey, many consumers do not trust celebrity endorsements in advertisements because they do not believe that the celebrities actually use the endorsed products. A scholar cites this as evidence that people have become more skeptical about advertisements compared to the past.
Which of the following, if true, would most weaken the scholar's argument?
(A) In the past, advertisements were designed to make people believe that celebrities used the endorsed products, but nowadays, advertisements are no longer designed with this intent.
(B) Consumers rarely pay attention to advertisements in general, but they do notice advertisements featuring celebrity endorsements.
(C) When a celebrity endorses a particular product, they often refuse to use competing products.
(D) Surveys indicate that celebrity endorsements still attract people's attention to the advertised products.
(E) Consumers today are less likely to believe advertisements they see in newspapers, hear on the radio, or watch on television compared to the past.

2.RC
Until the 1980s, most scientists believed that no catastrophic geological processes caused the extinction of dinosaurs that occurred approximately 66 million years ago, at the end of the Cretaceous period. Geologists argued that a dramatic drop in sea level coincided with the extinction of the dinosaurs and could have caused the climatic changes that resulted in this extinction as well as the extinction of many ocean species.

This view was seriously challenged in the 1980s by the discovery of large amounts of iridium in a layer of clay deposited at the end of the Cretaceous period. Because iridium is extremely rare in rocks on the Earth’s surface but common in meteorites, researchers theorized that it was the impact of a large meteorite that dramatically changed the earth’s climate and thus triggered the extinction of the dinosaurs.

Currently available evidence, however, offers more support for a new theory, the volcanic-eruption theory. A vast eruption of lava in India coincided with the extinctions that occurred at the end of the Cretaceous period, and the release of carbon dioxide from this episode of volcanism could have caused the climatic change responsible for the demise of the dinosaurs. Such outpourings of lava are caused by instability in the lowest layer of the Earth’s mantle, located just above the Earth’s core. As the rock that constitutes this layer is heated by the Earth’s core, it becomes less dense and portions of it eventually escape upward as blobs or molten rock, called “diapirs,” that can, under certain circumstances, erupt violently through the Earth’s crust.

Moreover, the volcanic-eruption theory, like the impact theory, accounts for the presence of iridium in sedimentary deposits; it also explains matters that the meteorite-impact theory does not. Although iridium is extremely rare on the Earth’s surface, the lower regions of the Earth’s mantle have roughly the same composition as meteorites and contain large amounts of iridium, which in the case of a diapir eruption would probably be emitted as iridium hexafluoride, a gas that would disperse more uniformly in the atmosphere than the iridium-containing matter thrown out from a meteorite impact. In addition, the volcanic-eruption theory may explain why the end of the Cretaceous period was marked by a gradual change in sea level. Fossil records indicate that for several hundred thousand years prior to the relatively sudden disappearance of the dinosaurs, the level of the sea gradually fell, causing many marine organisms to die out. This change in sea level might well have been the result of a distortion in the Earth’s surface that resulted from the movement of diapirs upward toward the Earth’s crust, and the more cataclysmic extinction of the dinosaurs could have resulted from the explosive volcanism that occurred as material from the diapirs erupted onto the Earth’s surface.

1. The author's stance on the cause of the extinction of the dinosaurs can best be described as
(A) firmly advocating for the volcanic-eruption theory over the meteorite-impact theory
(B) suggesting that the volcanic-eruption theory is more plausible than the meteorite-impact theory based on currently available evidence
(C) arguing that the meteorite-impact theory and the volcanic-eruption theory are equally supported by the evidence
(D) implying that neither the volcanic-eruption theory nor the meteorite-impact theory can fully account for the extinction of the dinosaurs
(E) maintaining that the cause of the extinction of the dinosaurs remains uncertain despite recent scientific discoveries

4. The passage implies that the lower regions of the Earth's mantle and meteorites have which of the following in common?
(A) They both contain large amounts of iridium.
(B) They are both less dense than the rock that constitutes the Earth's core.
(C) They are both more likely to escape upward as diapirs than the rock in higher layers of the Earth's mantle.
(D) They both have the potential to cause climatic changes when they erupt or impact the Earth's surface.
(E) They both played a role in the extinction of the dinosaurs at the end of the Cretaceous period.

5. The author's argument in favor of the volcanic-eruption theory over the meteorite-impact theory relies most heavily on which of the following assumptions?
(A) The iridium found in sedimentary deposits at the end of the Cretaceous period was more likely to have been emitted from a diapir eruption than from a meteorite impact.
(B) The climatic changes that resulted in the extinction of the dinosaurs were more likely to have been caused by the release of carbon dioxide from a vast eruption of lava than by the impact of a large meteorite.
(C) The gradual change in sea level prior to the extinction of the dinosaurs is more consistent with the volcanic-eruption theory than with the meteorite-impact theory.
(D) The distortion in the Earth's surface that resulted from the movement of diapirs is more likely to have caused the extinction of the dinosaurs than the impact of a large meteorite.
(E) The explosive volcanism that occurred as material from the diapirs erupted onto the Earth's surface is more likely to have caused the sudden disappearance of the dinosaurs than the impact of a large meteorite.

The Italian luxury industry, a bastion of unparalleled craftsmanship and iconic brands, has undergone a profound metamorphosis over the past two decades. Propelled by the inexorable forces of globalization, digital disruption, and the capricious whims of consumer preferences, the industry has had to deftly navigate an increasingly labyrinthine and mercurial market landscape to maintain its preeminence.

According to data from the Italian National Institute of Statistics (ISTAT), the Italian luxury sector generated a total revenue of €76 billion in 2019, representing a 3.2% increase from the previous year. This growth was primarily fueled by robust demand from international markets, particularly the burgeoning economies of Asia and the opulent Middle East, which accounted for approximately 60% of total sales. The industry's success can be attributed to its uncanny ability to leverage its rich cultural tapestry, innovative design capabilities, and unwavering commitment to quality to create highly covetable products that command stratospheric prices.

However, the industry also faces a panoply of formidable challenges, including the escalating cost of raw materials, the imperative for sustainable production practices, and the pernicious threat of counterfeiting. In 2019, the Italian government estimated that counterfeit luxury goods cost the industry over €10 billion in lost revenue annually, representing a staggering erosion of the sector's profitability.

To address these challenges, Italian luxury brands have made prodigious investments in digital technologies, such as e-commerce platforms, social media marketing, and artificial intelligence-powered customer service. These investments have allowed brands to extend their reach, forge connections with younger and more heterogeneous customer segments, and create more bespoke and immersive shopping experiences. For example, Gucci, one of Italy's most legendary luxury brands, reported that online sales accounted for 13% of its total revenue in 2019, a meteoric rise from just 4% in 2015.

In addition to digital transformation, Italian luxury brands have also embraced sustainability as a cardinal driver of long-term value creation. Many brands have implemented eco-friendly production processes, such as the use of renewable energy and recycled materials, and have forged alliances with environmental organizations to promote conservation and biodiversity. For instance, Prada Group, which owns several illustrious Italian luxury brands, has pledged to using only recycled nylon in its products by 2021, as part of its overarching sustainability strategy.

Despite these herculean efforts, the Italian luxury industry remains susceptible to the vicissitudes of economic and geopolitical risks, such as trade tensions, currency fluctuations, and the unrelenting COVID-19 pandemic. In 2020, the industry suffered a vertiginous contraction in sales, with revenue plummeting by an estimated 20-25% compared to the previous year. However, most analysts expect the industry to rebound with alacrity in 2021, buoyed by pent-up demand and the gradual reopening of key markets.

Looking ahead, the Italian luxury industry must continue to innovate and adapt to the protean needs and preferences of global consumers. This will require copious investments in new technologies, sustainable production practices, and talent development to ensure that the industry remains at the vanguard of creativity and excellence. By embracing these challenges and opportunities with alacrity and aplomb, the Italian luxury industry can cement its position as a paragon in the global luxury market and continue to create value for its stakeholders for generations to come.
