Archaeologists studying ancient Maya pottery have discovered that it contains a material which can be used to accurately date the artifacts. However, this material degrades over time, making it difficult to determine the age of older pottery. Interestingly, an identical dating material is found in modern Maya pottery. Which of the following, if true, would best explain the presence of the dating material in both ancient and modern Maya pottery?
(A) The climate conditions in Maya regions have remained stable over the last several millennia, slowing the deterioration of pottery.
(B) Maya potters have closely guarded the secret of their pottery techniques, passing them down through generations.
(C) Archaeologists often consult modern Maya potters to better understand ancient pottery manufacturing methods.
(D) The dating material is naturally occurring and is still readily available in the clay sources used by modern Maya potters.
(E) Some Maya pottery was not fired at high enough temperatures to fully harden the clay, making it more susceptible to deterioration.

A country is planning to replace its $1 bills with $1 coins. Although the coins have a higher production cost per unit than the bills, the government estimates this change will result in significant cost savings over the next several decades. Which of the following, if true, most helps to explain these projected savings?
(A) The $1 coins will be made primarily from a low-cost metal alloy that is unlikely to appreciate in value over time.
(B) It is less expensive for the government to store large quantities of coins in secure facilities compared to storing bills.
(C) When citizens lose bills or take them out of circulation to save as collectibles, it creates a net cost for the government.
(D) The government plans to set aside a portion of the savings from switching to $1 coins to fund anti-counterfeiting measures.
(E) On average, a $1 bill remains in circulation for approximately 6 years before wearing out, while $1 coins typically last over 30 years.

IN THE decades-long duel for naval supremacy that was fought out between Britain and France at the end of the 18th century, the British fleet had a secret weapon. It was, as secret weapons often are, hugely expensive. But it paid off, giving British ships more speed, manoeuvrability and staying power than their French rivals. It was copper.By covering the underwater parts of their ships' hulls with copper plates, which slowly dissolved, releasing toxic copper ions as they did so, the British admirals stopped barnacles, mussels and burrowing clams from taking up residence. In fleets that were otherwise well-matched the result was decisive. France lost. The British Empire became the global superpower of the 19th century. And the world speaks English, not French.

Ship-fouling, then, can have serious consequences. Even now, when naval supremacy is less of an issue, the problem is rife. The drag imposed by a heavy infestation of barnacles may push a ship's fuel consumption up by as much as 40%. The solution usually adopted is similar to the Royal Navy's: poison. Copper is still used, though in the form of copper-containing paint. Another popular chemical is tri-butyl tin. But releasing toxic heavy metals into the sea is frowned on these days—indeed, tri-butyl tin is now illegal in many places—so the search is on for alternatives.

One possibility is to use one of a group of chemicals called avermectins. These are antiparasite agents (the most familiar is called, confusingly, ivermectin) that are used against fleas and gut worms. They also, according to Hans Elwing of the University of Gothenburg, in Sweden, prevent barnacle colonies from taking hold by stunting their growth. A barnacle that runs into the chemical finds it cannot bind as strongly to the surface. Only a tiny amount, about one part in a thousand of the paint by weight, is needed, and other marine species are not, as far as can be ascertained, affected. Another way of discouraging barnacles is to confuse them. A formula developed by Giancarlo Galli of the University of Pisa uses polymer molecules that are water-attracting on one side and water-repellent on the other. When they are painted onto a surface this arrangement forces them into a kind of chequerboard pattern which makes it much harder for barnacles and mussels to stick, according to David Williams, who is in charge of commercialising the idea at AkzoNobel, a multinational chemical company.

If chequerboarding does not work out, AkzoNobel has an alternative: create a surface so smooth that barnacles cannot hold onto it. This is done using a fluoropolymer—a chemical similar in structure to Teflon. The paint does not stop the animals attaching themselves to a hull in the first place, but once the vessel is moving faster than ten knots, the water sweeps them away. That is no problem for commercial vessels, which are always on the go. But for pleasure boats, which may spend a lot of time idle, Dr Williams's team is trying to improve the formula so that a boat need not be moving so fast before the paint does its job.

Small boats, particularly on inland waterways, are also the target of work by John Schetz of the University of North Texas and Robert McMahon, of the University of Texas. They have been experimenting with a mixture containing a molecule similar to capsaicin (the active ingredient of hot peppers) and another that is similar to THC (the active ingredient of cannabis).

Fouling is less of a problem for boats in fresh water, as barnacles are purely marine. But, recently, the inland waterways, docks and freshwater-intakes of North America have been overrun by zebra and quagga mussels—species that originate from the area around the Black Sea. The mixture Dr Schetz and Dr McMahon have come up with seems particularly effective against these animals, though they have yet to commercialize it.

Their aim is not just to help boat owners, but also to stop them unwittingly spreading the mussels still further. According to Dr McMahon, a big part of the problem is that both species can survive out of the water for several days, so transporting a boat overland from one river basin to another, as is common practice in North America, will not necessarily kill them. Also, boat owners are not always as diligent as they might be about inspecting their vessels for signs of infestation—and even if they do look, the mussels can be hard to see, especially when they are young, and therefore small.

There is thus a lot to play for. Saving fuel will save money, as well as cutting shipping's contribution to greenhouse-gas emissions. And stopping the spread of invasive mussels will make life easier for those who run the waterways of America and Canada. The prize may not, this time round, be world domination. But whoever comes up with the winning formula is at least likely to become rich.

Yuefu poetry, which emerged during the Han Dynasty (206 BCE - 220 CE), represents a significant development in the history of classical Chinese literature. Originally referring to the Music Bureau, a government institution responsible for collecting and managing musical performances, Yuefu gradually evolved into a distinct poetic genre. Yuefu poems often drew inspiration from folk songs and ballads, reflecting the lives and experiences of common people, while also incorporating elements of court music and entertainment. This unique blend of popular and elite culture imbued Yuefu poetry with a vibrant, expressive, and emotionally resonant quality.

One of the defining characteristics of Yuefu poetry is its use of the "Bi Xing" (比兴) technique, which involves the use of metaphor, allusion, and symbolism to convey complex emotions and ideas. Through vivid imagery and evocative language, Yuefu poets sought to create a rich tapestry of meaning that could engage the reader's imagination and stir their feelings. This emphasis on emotional expression and artistic craftsmanship set Yuefu poetry apart from earlier forms of Chinese poetry, which often focused on moral didacticism or political commentary.

Another notable feature of Yuefu poetry is its thematic diversity. Yuefu poems cover a wide range of subjects, from love and romance to war and politics, from the joys and sorrows of everyday life to the grandeur and majesty of the natural world. This breadth of subject matter reflects the genre's origins in popular culture, as well as its ability to adapt to the changing tastes and concerns of Chinese society over time.

Some of the most famous examples of Yuefu poetry include "Mo Shang San" (陌上桑), a poem about a young woman's longing for her absent lover; "Mu Lan Ci" (木兰辞), which tells the story of a legendary female warrior; and "Gu Shi Shi Jiu Shou" (古诗十九首), a collection of nineteen poems that showcase the range and depth of Yuefu artistry. These and other classic Yuefu poems have had a lasting impact on Chinese literature, influencing generations of poets and writers up to the present day.

Despite its many achievements, Yuefu poetry also faced challenges and criticisms during its development. Some scholars argued that the genre's emphasis on emotionalism and individualism undermined the Confucian values of restraint and social harmony. Others claimed that the increasing popularity of Yuefu poems among the literati class led to a decline in artistic quality, as poets began to focus more on technical virtuosity than on authentic expression.

Nevertheless, the legacy of Yuefu poetry endures as a testament to the creativity, passion, and resilience of the Chinese poetic tradition. Its influence can be seen in later poetic forms such as the Shi (诗) and Ci (词), as well as in the works of countless individual poets who drew inspiration from its themes, techniques, and aesthetic principles. Today, Yuefu poetry remains an important subject of study and appreciation for scholars and enthusiasts of Chinese literature around the world.
