The principal of a school, which primarily relies on donations for its revenue, suggests hiring a fundraiser to increase the school's funds. The principal believes this will significantly boost the school's financial health. However, a group of stakeholders contends that the focus should not be on merely increasing the fund through donations, but rather on effectively managing and investing the current funds to generate higher returns. They argue that hiring a financial or investment expert would be more beneficial. The school's fund has consistently shown losses in the past few years.
Which of the following, if true, most strongly supports the stakeholders' argument against hiring a fundraiser?
A. Many schools similar in size and revenue to this school have successfully increased their funds through effective financial management.
B. The school's current fundraising strategies have not been updated in several years and are considered outdated by industry standards.
C. A recent survey shows that the potential for increasing donations significantly is limited due to economic downturns.
D. The school's fund has a history of mismanagement, leading to consistent losses over the past few years.
E. Other schools have seen substantial increases in their funds after hiring experienced fundraisers.

The Ming Dynasty (1368-1644) was a pivotal period in Chinese history, marked by significant achievements in politics, economy, culture, and science. Founded by Zhu Yuanzhang, a former Buddhist monk who led a successful rebellion against the Mongol-ruled Yuan Dynasty, the Ming Dynasty ushered in an era of native Chinese rule and ushered in a golden age of stability and prosperity.

Under the Ming emperors, particularly during the reigns of the Yongle Emperor (1402-1424) and the Wanli Emperor (1572-1620), China underwent a remarkable transformation. The Yongle Emperor, known for his ambitious projects and military conquests, expanded the Ming territory to its greatest extent, reaching as far as Central Asia and the South China Sea. He also moved the capital from Nanjing to Beijing and constructed the magnificent Forbidden City, which would serve as the imperial palace for the remainder of the dynasty.

The Ming Dynasty is also renowned for its cultural achievements, particularly in the fields of literature, art, and architecture. Ming writers produced a wealth of literary works, including novels, poetry, and essays, that explored themes of social criticism, personal reflection, and philosophical inquiry. The novel "Journey to the West," attributed to Wu Cheng'en, is one of the most famous works of Chinese literature and has had a profound influence on Chinese culture.

In the realm of art, the Ming Dynasty is known for its exquisite porcelain, which was highly prized both in China and abroad. Jingdezhen, a city in Jiangxi Province, became the center of porcelain production and exported its wares to Europe, the Middle East, and Southeast Asia. Ming artists also excelled in painting, calligraphy, and jade carving, producing works of great beauty and technical skill.

The Ming Dynasty was also a period of significant scientific and technological advancement. Ming scientists made important contributions to mathematics, astronomy, medicine, and engineering. The Chinese mathematician Zhu Zaiyu, for example, developed a system of equal temperament tuning for musical instruments, which would later be adopted in Europe. Ming astronomers, such as Guo Shoujing and Xu Guangqi, made precise observations of celestial phenomena and compiled star catalogues that were used for centuries.

In the field of medicine, Li Shizhen compiled the "Compendium of Materia Medica," a comprehensive work on herbal medicine that described over 1,800 medicinal substances and their uses. The work was widely circulated and translated into several languages, influencing the development of traditional medicine in China and beyond.

The Ming Dynasty also saw significant developments in agriculture, with the introduction of new crops such as maize, sweet potatoes, and peanuts from the Americas. These crops helped to diversify the Chinese diet and improve food security, particularly in times of drought or famine. Ming farmers also developed new techniques for irrigation, fertilization, and pest control, which increased agricultural productivity and supported the growing population.

However, the Ming Dynasty was not without its challenges and controversies. The cost of maintaining a large bureaucracy, a standing army, and a network of tributary states placed a heavy burden on the state coffers. The Ming court also faced criticism for its handling of foreign relations, particularly with regard to the tributary system and the Wokou raids by Japanese pirates along the Chinese coast.

In the late Ming period, the dynasty began to decline due to a combination of factors, including corruption, social unrest, and external threats. The Manchu, a nomadic people from the northeast, took advantage of the weakened Ming state and launched an invasion in 1644. After months of fighting, the Manchu forces captured Beijing and established the Qing Dynasty, which would rule China for nearly three centuries.

Despite its eventual fall, the Ming Dynasty left a lasting legacy on Chinese history and culture. Its achievements in art, literature, science, and technology continue to be celebrated and studied to this day. The Ming period also saw the height of China's maritime exploration, with the voyages of Admiral Zheng He to Southeast Asia, South Asia, and East Africa, which expanded Chinese influence and trade networks.

In conclusion, the Ming Dynasty was a complex and fascinating period in Chinese history, marked by great achievements and challenges. Its legacy continues to shape Chinese culture and identity to this day, and its impact can be felt in fields as diverse as art, science, and politics. As one of the most important dynasties in Chinese history, the Ming Dynasty offers a rich and compelling subject for study and reflection.

3.RC
The advent of Global Positioning System (GPS) dropwindsondes in 1997 has revolutionized the way forecasters assess the intensity of hurricanes. These sophisticated measuring devices, deployed from hurricane reconnaissance aircraft into the eyewall—the region of the storm with the highest wind speeds—have provided unprecedented insights into the true strength of these catastrophic phenomena. The dropwindsondes measure crucial meteorological parameters such as temperature, barometric pressure, water vapor, and wind speed at 15-foot intervals as they descend through the hurricane's inner core.

Prior to the introduction of dropwindsondes, the estimation of a hurricane's maximum sustained surface wind posed a significant challenge for operational tropical cyclone forecasters. Even when aircraft reconnaissance data were available, they were typically obtained at the 700 mb (10,000 ft) level, leaving forecasters to extrapolate the surface winds based on these flight-level observations. Various studies, such as that by Powell and Black (1990), suggested using a reduction ratio of 63%-73% to convert flight-level wind observations to surface wind speeds. The National Hurricane Center (NHC) has historically employed higher ratios, ranging from 80%-90%, which has occasionally drawn criticism regarding the accuracy of their intensity estimates.

The analysis of dropwindsonde data from Hurricane Andrew in 1992 revealed that the maximum sustained surface wind speed was approximately 90% of the wind speed measured at the 10,000-foot aircraft level as the storm approached south Florida. This finding led to a revision of Andrew's estimated wind speeds from 145 mph to 165 mph, highlighting the significance of accurate surface wind measurements.

This study examines a comprehensive dataset of 357 quality-controlled eyewall profiles obtained from multiple hurricanes between 1997 and 1999. The majority of these dropsonde releases were made from the 700 mb level, with airborne radar and operational air-crew comments used to verify the eyewall location. The individual soundings were normalized by the wind speed at 700 mb to construct a mean eyewall profile.

The results demonstrate that the strongest winds in the eyewall occur near 500 m (1600 ft) elevation, approximately 20% higher than the 700 mb wind due to the warm-core nature of tropical cyclones. The ratio of surface to 700 mb wind (R700) is 0.91 in the eyewall, compared to 0.78 in the outer vortex. However, individual eyewall profiles, such as those from Hurricane Mitch in 1998, illustrate the challenges in estimating surface winds from flight-level reconnaissance data. Mitch exhibited much higher wind speeds near the surface despite relatively lower flight-level winds, suggesting a weakening trend from the "top-down."

Based on these analyses, the study recommends the following reduction factors for converting flight-level winds in the inner core of a tropical cyclone to surface (33 ft) level: 0.90 for the 700 mb level, 0.80 for the 850 mb level (commonly flown in tropical storms), and 0.85 for investigative flights at 1,000 ft. These guidelines can be modified based on storm-specific conditions, with variability influenced by wind speed, cyclone convective intensity, and sea-surface temperature.

The mean eyewall profile also has implications for high-rise buildings and elevated terrain. Winds at the top of a 30-story building will average about 20 mph (one Saffir-Simpson category) higher than at the surface, as demonstrated by an example from Hurricane Georges. Understanding these vertical wind speed variations is crucial for assessing the potential impact of hurricanes on coastal infrastructure and communities.
