QUES: Old English (nglisc, Anglisc, Englisc) or Anglo-Saxon is the earliest historical form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages. It was brought to Great Britain by Anglo-Saxon settlers probably in the mid 5th century, and the first Old English literary works date from the mid 7th century. After the Norman Conquest of 1066, English was replaced for a time as the language of the upper classes by Anglo-Norman, a relative of French, and Old English developed into the next historical form of English, known as Middle English.

What people brought Old English to Britain?
What is the answer?
ANS: Anglo-Saxon settlers
QUES: The Han dynasty inherited the ban liang coin type from the Qin. In the beginning of the Han, Emperor Gaozu closed the government mint in favor of private minting of coins. This decision was reversed in 186 BC by his widow Grand Empress Dowager Lu Zhi (d. 180 BC), who abolished private minting. In 182 BC, Lu Zhi issued a bronze coin that was much lighter in weight than previous coins. This caused widespread inflation that was not reduced until 175 BC when Emperor Wen allowed private minters to manufacture coins that were precisely 2.6 g (0.09 oz) in weight.

In what year was the decision reversing the closure of the government mint implemented?
What is the answer?
ANS: 186 BC
QUES: Synapses are the key functional elements of the brain. The essential function of the brain is cell-to-cell communication, and synapses are the points at which communication occurs. The human brain has been estimated to contain approximately 100 trillion synapses; even the brain of a fruit fly contains several million. The functions of these synapses are very diverse: some are excitatory (exciting the target cell); others are inhibitory; others work by activating second messenger systems that change the internal chemistry of their target cells in complex ways. A large number of synapses are dynamically modifiable; that is, they are capable of changing strength in a way that is controlled by the patterns of signals that pass through them. It is widely believed that activity-dependent modification of synapses is the brain's primary mechanism for learning and memory.

The primary job of the brain is what?
What is the answer?
ANS:
cell-to-cell communication
