Problem: Communication:

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?
---
A: animal emotions, animal culture and learning


Problem: Karl Popper:

In All Life is Problem Solving, Popper sought to explain the apparent progress of scientific knowledge – that is, how it is that our understanding of the universe seems to improve over time. This problem arises from his position that the truth content of our theories, even the best of them, cannot be verified by scientific testing, but can only be falsified. Again, in this context the word "falsified" does not refer to something being "fake"; rather, that something can be (i.e., is capable of being) shown to be false by observation or experiment. Some things simply do not lend themselves to being shown to be false, and therefore, are not falsifiable. If so, then how is it that the growth of science appears to result in a growth in knowledge? In Popper's view, the advance of scientific knowledge is an evolutionary process characterised by his formula:

What was the advance of scientific knowledge in Einstein's view?

A: unanswerable


Problem: Tajikistan:

Russian Imperialism led to the Russian Empire's conquest of Central Asia during the late 19th century's Imperial Era. Between 1864 and 1885 Russia gradually took control of the entire territory of Russian Turkestan, the Tajikistan portion of which had been controlled by the Emirate of Bukhara and Khanate of Kokand. Russia was interested in gaining access to a supply of cotton and in the 1870s attempted to switch cultivation in the region from grain to cotton (a strategy later copied and expanded by the Soviets).[citation needed] By 1885 Tajikistan's territory was either ruled by the Russian Empire or its vassal state, the Emirate of Bukhara, nevertheless Tajiks felt little Russian influence.[citation needed]

Between 1964 and 1985 Russia gradually took control of what?
---
A: unanswerable


Problem: North Carolina:

North Carolina became one of the English Thirteen Colonies and with the territory of South Carolina was originally known as the Province of Carolina. The northern and southern parts of the original province separated in 1729. Originally settled by small farmers, sometimes having a few slaves, who were oriented toward subsistence agriculture, the colony lacked cities or towns. Pirates menaced the coastal settlements, but by 1718 the pirates had been captured and killed. Growth was strong in the middle of the 18th century, as the economy attracted Scots-Irish, Quaker, English and German immigrants. The colonists generally supported the American Revolution, as the number of Loyalists was smaller than in some other colonies.

What was the profession of most of the settlers in the Province of Carolina?
---
A:
small farmers
