Problem: By the late 19th century, the most conservative elements within the Qing court could no longer ignore China's military weakness. In 1860, during the Second Opium War, the capital Beijing was captured and the Summer Palace sacked by a relatively small Anglo-French coalition force numbering 25,000. The advent of modern weaponry resulting from the European Industrial Revolution had rendered China's traditionally trained and equipped army and navy obsolete. The government attempts to modernize during the Self-Strengthening Movement were initially successful, but yielded few lasting results because of the central government's lack of funds, lack of political will, and unwillingness to depart from tradition.
How big was the French-British army?
The answer is the following: 25,000

Problem: Homer refers to the "Hellenes" (/hlinz/) as a relatively small tribe settled in Thessalic Phthia, with its warriors under the command of Achilleus. The Parian Chronicle says that Phthia was the homeland of the Hellenes and that this name was given to those previously called Greeks (). In Greek mythology, Hellen, the patriarch of Hellenes, was son of Pyrrha and Deucalion, who ruled around Phthia, the only survivors after the great deluge. It seems that the myth was invented when the Greek tribes started to separate from each other in certain areas of Greece and it indicates their common origin. Aristotle names ancient Hellas as an area in Epirus between Dodona and the Achelous river, the location of the great deluge of Deucalion, a land occupied by the Selloi and the "Greeks" who later came to be known as "Hellenes". Selloi were the priests of Dodonian Zeus and the word probably means "sacrificers" (compare Gothic saljan, "present, sacrifice"). There is currently no satisfactory etymology of the name Hellenes. Some scholars assert that the name Selloi changed to Sellanes and then to Hellanes-Hellenes. However this etymology connects the name Hellenes with the Dorians who occupied Epirus and the relation with the name Greeks given by the Romans becomes uncertain. The name Hellenes seems to be older and it was probably used by the Greeks with the establishment of the Great Amphictyonic League. This was an ancient association of Greek tribes with twelve founders which was organized to protect the great temples of Apollo in Delphi (Phocis) and of Demeter near Thermopylae (Locris). According to the legend it was founded after the Trojan War by the eponymous Amphictyon, brother of Hellen.
Who is this small group named for ?
The answer is the following: Hellen, the patriarch of Hellenes

Problem: In the Southern Netherlands (now Belgium and Luxembourg) developments were different. Under Spanish, then Austrian, and then French rule standardisation of Dutch language came to a standstill. The state, law, and increasingly education used French, yet more than half the Belgian population were speaking a Dutch dialect. In the course of the nineteenth century the Flemish movement stood up for the rights of Dutch, mostly called Flemish. But in competing with the French language the variation in dialects was a serious disadvantage. Since standardisation is a lengthy process, Dutch-speaking Belgium associated itself with the standard language that had already developed in the Netherlands over the centuries. Therefore, the situation in Belgium is essentially no different from that in the Netherlands, although there are recognisable differences in pronunciation, comparable to the pronunciation differences between standard British and standard American English. In 1980 the Netherlands and Belgium concluded the Language Union Treaty. This treaty lays down the principle that the two countries must gear their language policy to each other, among other things, for a common system of spelling.
The commonality between Dutch spoken by people in the Netherlands and Dutch-speaking Belgium can be compared to the relationship between British English and what language?
The answer is the following: American English

Problem: While successful predation results in a gain of energy, hunting invariably involves energetic costs as well. When hunger is not an issue, in general most predators will not seek to attack prey since the costs outweigh the benefits. For instance, a large predatory fish like a shark that is well fed in an aquarium will typically ignore the smaller fish swimming around it (while the prey fish take advantage of the fact that the apex predator is apparently uninterested). Surplus killing represents a deviation from this type of behaviour. The treatment of consumption in terms of cost-benefit analysis is known as optimal foraging theory, and has been quite successful in the study of animal behavior. In general, costs and benefits are considered in energy gain per unit time, though other factors are also important, such as essential nutrients that have no caloric value but are necessary for survival and health.
What makes predation successful?
The answer is the following:
gain of energy
