Problem: Each successive rank gave its holder greater pensions and legal privileges. The highest rank, of full marquess, came with a state pension and a territorial fiefdom. Holders of the rank immediately below, that of ordinary marquess, received a pension, but had no territorial rule. Officials who served in government belonged to the wider commoner social class and were ranked just below nobles in social prestige. The highest government officials could be enfeoffed as marquesses. By the Eastern Han period, local elites of unattached scholars, teachers, students, and government officials began to identify themselves as members of a larger, nationwide gentry class with shared values and a commitment to mainstream scholarship. When the government became noticeably corrupt in mid-to-late Eastern Han, many gentrymen even considered the cultivation of morally grounded personal relationships more important than serving in public office.
What was considered to be more important to some than serving the local government?
The answer is the following: cultivation of morally grounded personal relationships

Problem: It is the third language of South Africa in terms of native speakers (~13.5%), of whom 53 percent are Coloureds and 42.4 percent Whites. In 1996, 40 percent of South Africans reported to know Afrikaans at least at a very basic level of communication. It is the lingua franca in Namibia, where it is spoken natively in 11 percent of households. In total, Afrikaans is the first language in South Africa alone of about 6.8 million people and is estimated to be a second language for at least 10 million people worldwide, compared to over 23 million and 5 million respectively, for Dutch.
Which country has 11% of households who speak Afrikaans?
The answer is the following: Namibia

Problem: Antarctica (US English i/ntrktk/, UK English /ntktk/ or /nttk/ or /ntk/)[Note 1] is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
What is the size of Antarctica?
The answer is the following: 14,000,000 square kilometres

Problem: The broad field of animal communication encompasses most of the issues in ethology. Animal communication can be defined as any behavior of one animal that affects the current or future behavior of another animal. The study of animal communication, called zoo semiotics (distinguishable from anthroposemiotics, the study of human communication) has played an important part in the development of ethology, sociobiology, and the study of animal cognition. Animal communication, and indeed the understanding of the animal world in general, is a rapidly growing field, and even in the 21st century so far, a great share of prior understanding related to diverse fields such as personal symbolic name use, animal emotions, animal culture and learning, and even sexual conduct, long thought to be well understood, has been revolutionized. A special field of animal communication has been investigated in more detail such as vibrational communication.
What are some fields of knowledge concerning the animal world that have been revolutionizes in the 21st century?
The answer is the following:
animal emotions, animal culture and learning
