Input: Read this: As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.
Question: What is one piece that makes up an antenna system?

Output: radio


QUES: Czech contains ten basic vowel phonemes, and three more found only in loanwords. They are /a/, /ɛ/, /ɪ/, /o/, and /u/, their long counterparts /aː/, /ɛː/, /iː/, /oː/ and /uː/, and three diphthongs, /ou̯/, /au̯/ and /ɛu̯/. The latter two diphthongs and the long /oː/ are exclusive to loanwords. Vowels are never reduced to schwa sounds when unstressed. Each word usually has primary stress on its first syllable, except for enclitics (minor, monosyllabic, unstressed syllables). In all words of more than two syllables, every odd-numbered syllable receives secondary stress. Stress is unrelated to vowel length, and the possibility of stressed short vowels and unstressed long vowels can be confusing to students whose native language combines the features (such as English).

Where does each word usually have primary stress in English?

QUES: Scientists are still debating when people started wearing clothes. Ralf Kittler, Manfred Kayser and Mark Stoneking, anthropologists at the Max Planck Institute for Evolutionary Anthropology, have conducted a genetic analysis of human body lice that suggests clothing originated quite recently, around 170,000 years ago. Body lice is an indicator of clothes-wearing, since most humans have sparse body hair, and lice thus require human clothing to survive. Their research suggests the invention of clothing may have coincided with the northward migration of modern Homo sapiens away from the warm climate of Africa, thought to have begun between 50,000 and 100,000 years ago. However, a second group of researchers using similar genetic methods estimate that clothing originated around 540,000 years ago (Reed et al. 2004. PLoS Biology 2(11): e340). For now, the date of the origin of clothing remains unresolved.[citation needed]

Sanskrit has also influenced Sino-Tibetan languages through the spread of Buddhist texts in translation. Buddhism was spread to China by Mahayana missionaries sent by Ashoka, mostly through translations of Buddhist Hybrid Sanskrit. Many terms were transliterated directly and added to the Chinese vocabulary. Chinese words like 剎那 chànà (Devanagari: क्षण kṣaṇa 'instantaneous period') were borrowed from Sanskrit. Many Sanskrit texts survive only in Tibetan collections of commentaries to the Buddhist teachings, the Tengyur.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What Sanskrit texts survive in Egyptian collections?
Ah, so.. unanswerable


Question: The Hellenistic states of Asia and Egypt were run by an occupying imperial elite of Greco-Macedonian administrators and governors propped up by a standing army of mercenaries and a small core of Greco-Macedonian settlers. Promotion of immigration from Greece was important in the establishment of this system. Hellenistic monarchs ran their kingdoms as royal estates and most of the heavy tax revenues went into the military and paramilitary forces which preserved their rule from any kind of revolution. Macedonian and Hellenistic monarchs were expected to lead their armies on the field, along with a group of privileged aristocratic companions or friends (hetairoi, philoi) which dined and drank with the king and acted as his advisory council. Another role that was expected the monarch fill was that of charitable patron of his people, this public philanthropy could mean building projects and handing out gifts but also promotion of Greek culture and religion.
Try to answer this question if possible: What type of estates did Hellenistic monarchs run their kingdoms?
Answer: royal estates


Context and question: Commercial credit and agricultural consumer loans were the main types of loans. The trade credit was usually extended by temples in order to finance trade expeditions and was nominated in silver. The interest rate was set at 1/60 a month (one shekel per mina) some time before 2000 BC and it remained at that level for about two thousand years. Rural loans commonly arose as a result of unpaid obligations due to an institution (such as a temple), in this case the arrears were considered to be lent to the debtor. They were denominated in barley or other crops and the interest rate was typically much higher than for commercial loans and could amount to 1/3 to 1/2 of the loan principal.
Who lent money to farmers to plant crops?
