Problem: Dog:

In breeding circles, a male canine is referred to as a dog, while a female is called a bitch (Middle English bicche, from Old English bicce, ultimately from Old Norse bikkja). A group of offspring is a litter. The father of a litter is called the sire, and the mother is called the dam. Offspring are, in general, called pups or puppies, from French poupée, until they are about a year old. The process of birth is whelping, from the Old English word hwelp.

What is the English word for female dog that has also become profanity?

A: bitch


Problem: Maximum power transfer requires matching the impedance of an antenna system (as seen looking into the transmission line) to the complex conjugate of the impedance of the receiver or transmitter. In the case of a transmitter, however, the desired matching impedance might not correspond to the dynamic output impedance of the transmitter as analyzed as a source impedance but rather the design value (typically 50 ohms) required for efficient and safe operation of the transmitting circuitry. The intended impedance is normally resistive but a transmitter (and some receivers) may have additional adjustments to cancel a certain amount of reactance in order to "tweak" the match. When a transmission line is used in between the antenna and the transmitter (or receiver) one generally would like an antenna system whose impedance is resistive and near the characteristic impedance of that transmission line in order to minimize the standing wave ratio (SWR) and the increase in transmission line losses it entails, in addition to supplying a good match at the transmitter or receiver itself.
What requires matching of the empedance to an antenna system?

Answer: Maximum power transfer

Gaddafi sought to develop closer links in the Maghreb; in January 1974 Libya and Tunisia announced a political union, the Arab Islamic Republic. Although advocated by Gaddafi and Tunisian President Habib Bourguiba, the move was deeply unpopular in Tunisia and soon abandoned. Retaliating, Gaddafi sponsored anti-government militants in Tunisia into the 1980s. Turning his attention to Algeria, in 1975 Libya signed the Hassi Messaoud defence agreement allegedly to counter "Moroccan expansionism", also funding the Polisario Front of Western Sahara in their independence struggle against Morocco. Seeking to diversify Libya's economy, Gaddafi's government began purchasing shares in major European corporations like Fiat as well as buying real estate in Malta and Italy, which would become a valuable source of income during the 1980s oil slump.
Against what government was the Hassi Messaoud defense agreement directed against?
A: Moroccan


Context and question: Vladimir's choice of Eastern Christianity may also have reflected his close personal ties with Constantinople, which dominated the Black Sea and hence trade on Kiev's most vital commercial route, the Dnieper River. Adherence to the Eastern Church had long-range political, cultural, and religious consequences. The church had a liturgy written in Cyrillic and a corpus of translations from Greek that had been produced for the Slavic peoples. This literature facilitated the conversion to Christianity of the Eastern Slavs and introduced them to rudimentary Greek philosophy, science, and historiography without the necessity of learning Greek (there were some merchants who did business with Greeks and likely had an understanding of contemporary business Greek). In contrast, educated people in medieval Western and Central Europe learned Latin. Enjoying independence from the Roman authority and free from tenets of Latin learning, the East Slavs developed their own literature and fine arts, quite distinct from those of other Eastern Orthodox countries.[citation needed] (See Old East Slavic language and Architecture of Kievan Rus for details ). Following the Great Schism of 1054, the Rus' church maintained communion with both Rome and Constantinople for some time, but along with most of the Eastern churches it eventually split to follow the Eastern Orthodox. That being said, unlike other parts of the Greek world, Kievan Rus' did not have a strong hostility to the Western world.
What did the West Slavs develop?
Answer: unanswerable


Question: Other sections of society included the nobility, clergy, and townsmen. Nobles, both the titled nobility and simple knights, exploited the manors and the peasants, although they did not own lands outright but were granted rights to the income from a manor or other lands by an overlord through the system of feudalism. During the 11th and 12th centuries, these lands, or fiefs, came to be considered hereditary, and in most areas they were no longer divisible between all the heirs as had been the case in the early medieval period. Instead, most fiefs and lands went to the eldest son.[R] The dominance of the nobility was built upon its control of the land, its military service as heavy cavalry, control of castles, and various immunities from taxes or other impositions.[S] Castles, initially in wood but later in stone, began to be constructed in the 9th and 10th centuries in response to the disorder of the time, and provided protection from invaders as well as allowing lords defence from rivals. Control of castles allowed the nobles to defy kings or other overlords. Nobles were stratified; kings and the highest-ranking nobility controlled large numbers of commoners and large tracts of land, as well as other nobles. Beneath them, lesser nobles had authority over smaller areas of land and fewer people. Knights were the lowest level of nobility; they controlled but did not own land, and had to serve other nobles.[T]
Is there an answer to this question: In what century were castles first built?

Answer: 9th

All equipment must be suitable for a mixed-gender force. Combat helmets, rucksacks, combat boots, and flak jackets are designed to ensure women have the same level of protection and comfort as their male colleagues. The women's uniform is similar in design to the men's uniform, but conforms to the female figure, and is functional and practical. Women are also provided with an annual financial entitlement for the purchase of brassiere undergarments.
What is a requirement for equipment for the CAF?
A:
equipment must be suitable for a mixed-gender force
